Minimum total system memory: 64 MB Non-ECC DIMMs Serial Presence Detect DDR400, DDR333, and DDR266 SDRAM DIMMs The board has two DIMM sockets and supports the following memory features: Table 3 lists the supported system bus frequency and memory speed combinations. Table 3. Supported System Bus Frequency and Memory Speed Combinations To use this type of DIMM... DDR400 DDR333 (Note) DDR266 The processor's system bus frequency must be... 800 MHz 800 or 533 MHz 800, 533, or 400 MHz Note: When using an 800 MHz system bus frequency processor, DDR333 memory is clocked at 320 MHz. This minimizes system latencies to optimize system throughput. NOTE To be fully compliant with all applicable DDR SDRAM memory specifications, the board should be populated with DIMMs that support the Serial Presence Detect (SPD) data structure. This enables the BIOS to read the SPD data and program the chipset to accurately configure memory settings for optimum performance. If non-SPD memory is installed, the BIOS will attempt to correctly configure the memory settings, but performance and reliability may be impacted or the DIMMs may not function under the determined frequency. 16 Product Description Table 4 lists the supported DIMM configurations.

DVMT ensures the most efficient use of available system memory for maximum 2-D/3-D graphics performance. Up to 64 MB of system memory can be allocated to DVMT on systems that have 256 MB or more of total system memory installed. Up to 32 MB can be allocated to DVMT on systems that have 128 MB but less than 256 MB of total installed system memory. Up to 8 MB can be allocated to DVMT when less than 128 MB of system memory is installed. DVMT returns system memory back to the operating system when the additional system memory is no longer required by the graphics subsystem. DVMT will always use a minimal fixed portion of system physical memory (as set in the BIOS Setup program) for compatibility with legacy applications. An example of this would be when using VGA graphics under DOS. Once loaded, the operating system and graphics drivers allocate additional system memory to the graphics buffer as needed for performing graphics functions. NOTE The use of DVMT requires operating system driver support. 1.5.1.4 Zone Rendering Technology (ZRT) The Intel Extreme Graphics 2 Controller supports Zone Rendering Technology (ZRT). ZRT is a process by which the screen is divided into several zones. Each zone is completely cached and rendered on chip before being written to the frame buffer. The benefits of ZRT include the following: * * * * * * Increased memory efficiency via better localization of data Increased on-chip processing speed due to decreased wait time for data Increased effective pixel fill rates Increased headroom for larger resolution and color depth Reduced power as a result of decreased memory bandwidth Reduction in depth and color bandwidth associated with conventional rendering 1.5.1.5 Rapid Pixel and Text Rendering (RPTR) The Rapid Pixel and Text Rendering Engine (RPTR) architecture utilizes special pipelines that allow 2D and 3D operations to overlap. By providing 8X compression, the RPTR engine reduces the memory bandwidth required to read texture memory, and reduces the amount of memory required for texture storage. A dedicated, non-blocking, multi-tier cache is provided for textures, colors, Z and vertex rendering. With single-pass, quad texture support, the drivers can submit up to four textures that pass to the graphics engine concurrently. The graphics core can switch between 2D and 3D operations without having to complete all operations of the same mode, which minimizes the overhead time required in switching between modes. 27 Intel Desktop Board D865GSA Technical Product Specification A 2D Block Level Transfer (BLT) in the RPTR engine is extended to 256-bit, which supports fast blitter fill rate. This enables the blitter sequence of the same addresses to access the cache and offloads the memory bandwidth required to support blitter fill rate. Then the cache is emptied automatically when the sequence of operations are complete. 1.5.1.6 Intelligent Memory Management (IMM) Intelligent Memory Management (IMM) technology is Intel's unique UMA memory manager architecture, consisting of these key elements: * * * Tiled memory addressing capability Deep display buffer implementation Dynamic data management scheme The memory addressing allows address remapping in the hardware for all graphics surfaces including textures, frame buffer, Z buffer, and video surfaces. Deep display buffers and dedicated screen refreshes improve visual performance, while the dynamic data management scheme manages burst size and page closing policies for memory accesses. IMM reduces the aggregate processor latency and allows longer in-page bursts for higher system performance. IMM also increases page coherency and improves memory efficiency in texture loads, 2D blitters, color/Z, MPEG2 motion compression, and other operations. 1.5.1.7 Video Mixing Renderer (VMR) The Intel Extreme Graphics 2 controller features VMR technology. VMR is a process where various data types can be blended together before being displayed. VMR allows applications to bend and twist images such as 3D textures so that special effects such as wipes, spins, and fades can be achieved. 1.5.1.8 PC/VCR Time Shifted Viewing PC/VCR requires a TV-tuner add-in card and a third party application. PC/VCR time shifted viewing allows the user to view and digitally record video pictures on their PC. Users can view stored images while recording and by using time-shifted viewing they can pause, resume, replay, and catch up to real time. The Intel Pentium 4 processor in combination with the Intel 82865G GMCH optimizes performance so that the video output is smooth without leaving any visual artifacts. Video tearing and corruption is prevented by the use of multiple buffers within the Intel Extreme Graphics 2 controller. 1.5.1.9 Bi-cubic Filtering Bi-cubic filtering is a new 4X4 filter that allows images to be generated more smoothly in the 3D pipeline. The bi-cubic filter can be used to improve image quality for all 3D texture engine components. 28 Product Description 1.5.1.10 AGP Digital Display (ADD) Card Support The GMCH routes two 12-bit multiplexed DVO ports that are each capable of driving a 165 MHz pixel clock to the AGP connector. The DVO ports can be paired for dual channel mode. In dual channel mode, the GMCH is capable of driving a 24-bit 330 MHz pixel clock. When an AGP add-in card is used, the Intel Extreme Graphics 2 controller is disabled and the AGP connector operates in AGP mode. When an ADD card is detected, the Intel Extreme Graphics 2 controller is enabled and the AGP connector is configured for DVO mode. DVO mode enables the DVO ports to be accessed by an ADD card. ADD cards can support up to two display devices with the following configurations: * * * * TV-Out Transition Minimized Differential Signaling (TMDS) Low Voltage Differential Signaling (LVDS) Single device operating in dual channel mode INTEGRATOR'S NOTES * * * Synchronous display is not supported when one of the display devices is a TV. Synchronous display with two digital displays is not supported. Digital Visual Interface (DVI) support is present only when an ADD card is installed. 1.5.2 * * * Universal 0.8 V / 1.5 V AGP 3.0 Connector 4x, 8x AGP 3.0 add-in cards with 0.8 V I/O 1x, 4x AGP 2.0 add-in cards with 1.5 V I/O AGP Digital Display (ADD) cards The AGP connector supports the following: AGP is a high-performance interface for graphics-intensive applications, such as 3D applications. While based on the PCI Local Bus Specification, Rev. 2.2, AGP is independent of the PCI bus and is intended for exclusive use with graphical display devices. AGP overcomes certain limitations of the PCI bus related to handling large amounts of graphics data with the following features: * * Pipelined memory read and write operations that hide memory access latency Demultiplexing of address and data on the bus for nearly 100 percent efficiency INTEGRATOR'S NOTES * * * AGP 2x operation is not supported. Install memory in the DIMM sockets prior to installing the AGP video card to avoid interference with the memory retention mechanism. The AGP connector is keyed for Universal 0.8 V AGP 3.0 cards or 1.5 V AGP 2.0 cards only. Do not attempt to install a legacy 3.3 V AGP card. The AGP connector is not mechanically compatible with legacy 3.3 V AGP cards. Refer to Figure 11, page 54 For information about The location of the AGP connector on the D865GSA board 29 Intel Desktop Board D865GSA Technical Product Specification 1.5.3 USB The board supports up to eight USB 2.0 ports, supports UHCI and EHCI, and uses UHCI- and EHCI-compatible drivers. The ICH5 provides the USB controller for all ports. The port arrangement is as follows: * * Four ports are implemented with stacked back panel connectors, adjacent to the audio connectors Four ports are routed to two separate front panel USB connectors NOTE Computer systems that have an unshielded cable attached to a USB port may not meet FCC Class B requirements, even if no device is attached to the cable. Use shielded cable that meets the requirements for full-speed devices. For information about The location of the USB connectors on the back panel The location of the front panel USB connectors Refer to Figure 10, page 53 Figure 11, page 54 1.5.4 * * IDE Support Two Parallel ATA IDE connectors, which support a total of four devices (two per connector) Two Serial ATA IDE connectors, which support one device per connector The board provides four IDE interface connectors: 1.5.4.1 Parallel ATA IDE Interfaces The ICH5's Parallel ATA IDE controller has two independent bus-mastering Parallel ATA IDE interfaces that can be independently enabled. The Parallel ATA IDE interfaces support the following modes: * * * * Programmed I/O (PIO): processor controls data transfer. 8237-style DMA: DMA offloads the processor, supporting transfer rates of up to 16 MB/sec. Ultra DMA: DMA protocol on IDE bus supporting host and target throttling and transfer rates of up to 33 MB/sec. ATA-66: DMA protocol on IDE bus supporting host and target throttling and transfer rates of up to 66 MB/sec. ATA-66 protocol is similar to Ultra DMA and is device driver compatible. ATA-100: DMA protocol on IDE bus allows host and target throttling. The ICH5's ATA-100 logic can achieve read transfer rates up to 100 MB/sec and write transfer rates up to 88 MB/sec. * NOTE ATA-66 and ATA-100 are faster timings and require a specialized cable to reduce reflections, noise, and inductive coupling. 30 Product Description The Parallel ATA IDE interfaces also support ATAPI devices (such as CD-ROM drives) and ATA devices. The BIOS supports Logical Block Addressing (LBA) and Extended Cylinder Head Sector (ECHS) translation modes. The drive reports the transfer rate and translation mode to the BIOS. For information about The location of the Parallel ATA IDE connectors Refer to Figure 11, page 54 1.5.4.2 Serial ATA Interfaces The ICH5's Serial ATA controller offers two independent Serial ATA ports with a theoretical maximum transfer rate of 150 MB/s per port. One device can be installed on each port for a maximum of two Serial ATA devices. A point-to-point interface is used for host to device connections, unlike Parallel ATA IDE which supports a master/slave configuration and two devices per channel. For compatibility, the underlying Serial ATA functionality is transparent to the operating system. The Serial ATA controller can operate in both legacy and native modes. In legacy mode, standard IDE I/O and IRQ resources are assigned (IRQ 14 and 15). In Native mode, standard PCI resource steering is used. Native mode is the preferred mode for configurations using the Windows* XP and Windows 2000 operating systems. NOTE Many Serial ATA drives use new low-voltage power connectors and require adaptors or power supplies equipped with low-voltage power connectors. For more information, see: http://www.serialata.org/ 31 Intel Desktop Board D865GSA Technical Product Specification 1.5.5 Real-Time Clock, CMOS SRAM, and Battery A coin-cell battery (CR2032) powers the real-time clock and CMOS memory. When the computer is not plugged into a wall socket, the battery has an estimated life of three years. When the computer is plugged in, the standby current from the power supply extends the life of the battery. The clock is accurate to 13 minutes/year at 25 C with 3.3 VSB applied. NOTE If the battery and AC power fail, custom defaults, if previously saved, will be loaded into CMOS RAM at power-on. When the voltage drops below a certain level, the BIOS Setup program settings stored in CMOS RAM (for example, the date and time) might not be accurate. Replace the battery with an equivalent one. Figure 1 on page 12 shows the location of the battery. CAUTION Risk of explosion if the battery is replaced with an incorrect type. Batteries should be recycled where possible.

The use of ACPI with the board requires an operating system that provides full ACPI support. ACPI features include: * * * * * * Plug and Play (including bus and device enumeration) Power management control of individual devices, add-in boards (some add-in boards may require an ACPI-aware driver), video displays, and hard disk drives Methods for achieving less than 15-watt system operation in the power-on/standby sleeping state A Soft-off feature that enables the operating system to power-off the computer Support for multiple wake-up events (see Table 14 on page 43) Support for a front panel power and sleep mode switch Table 12 lists the system states based on how long the power switch is pressed, depending on how ACPI is configured with an ACPI-aware operating system. Table 12. Effects of Pressing the Power Switch If the system is in this state... Off (ACPI G2/G5 - Soft off) On (ACPI G0 - working state) On (ACPI G0 - working state) Sleep (ACPI G1 - sleeping state) Sleep (ACPI G1 - sleeping state) ...and the power switch is pressed for Less than four seconds Less than four seconds More than four seconds Less than four seconds More than four seconds ...the system enters this state Power-on (ACPI G0 - working state) Soft-off/Standby (ACPI G1 - sleeping state) Fail safe power-off (ACPI G2/G5 - Soft off) Wake-up (ACPI G0 - working state) Power-off (ACPI G2/G5 - Soft off) 41 Intel Desktop Board D865GSA Technical Product Specification 1.10.1.1 System States and Power States Under ACPI, the operating system directs all system and device power state transitions. The operating system puts devices in and out of low-power states based on user preferences and knowledge of how devices are being used by applications. Devices that are not being used can be turned off. The operating system uses information from applications and user settings to put the system as a whole into a low-power state. Table 13 lists the power states supported by the board along with the associated system power targets. See the ACPI specification for a complete description of the various system and power states.

Dependent on the standby power consumption of wake-up devices used in the system. 42 Product Description 1.10.1.2 Wake-up Devices and Events Table 14 lists the devices or specific events that can wake the computer from specific states. Table 14. Wake-up Devices and Events These devices/events can wake up the computer... LAN Modem (back panel Serial Port A) PME# signal Power switch PS/2 devices RTC alarm USB ...from this state S1, S3, S4, S5 (Note) S1, S3 S1, S3, S4, S5 (Note) S1, S3, S4, S5 S1, S3 S1, S3, S4, S5 S1, S3 Note: For LAN and PME# signal, S5 is disabled by default in the BIOS Setup program. Setting this option to Power On will enable a wake-up event from LAN in the S5 state. NOTE The use of these wake-up events from an ACPI state requires an operating system that provides full ACPI support. In addition, software, drivers, and peripherals must fully support ACPI wake events. 1.10.2 Hardware Support CAUTION Ensure that the power supply provides adequate +5 V standby current if LAN wake capabilities and Instantly Available PC technology features are used. Failure to do so can damage the power supply. The total amount of standby current required depends on the wake devices supported and manufacturing options. The board provides several power management hardware features, including: * * * * * * * * Power connector Fan connectors LAN wake capabilities Instantly Available PC technology Resume on Ring Wake from USB Wake from PS/2 keyboard PME# signal wake-up support LAN wake capabilities and Instantly Available PC technology require power from the +5 V standby line. The sections discussing these features describe the incremental standby power requirements for each. 43 Intel Desktop Board D865GSA Technical Product Specification Resume on Ring enables telephony devices to access the computer when it is in a power-managed state. The method used depends on the type of telephony device (external or internal). NOTE The use of Resume on Ring and Wake from USB technologies from an ACPI state requires an operating system that provides full ACPI support. 1.10.2.1 Power Connector ATX12V-compliant power supplies can turn off the system power through system control. When an ACPI-enabled system receives the correct command, the power supply removes all non-standby voltages. When resuming from an AC power failure, the computer returns to the power state it was in before power was interrupted (on or off). The computer's response can be set using the Last Power State feature in the BIOS Setup program's Boot menu. For information about The location of the power connector The signal names of the power connector Refer to Figure 11, page 54 Table 29, page 57 1.10.2.2 * * * * * Fan Connectors The function/operation of the fan connectors is as follows: The fans are on when the board is in the S0 or S1 state. The fans are off when the board is off or in the S3, S4, or S5 state. Each fan connector is wired to a fan tachometer input of the hardware monitoring and fan control ASIC. All fan connectors support closed-loop fan control that can adjust the fan speed or switch the fan on or off as needed. All fan connectors have a +12 V DC connection. Refer to Figure 11, page 54 Table 23, page 56 Table 22, page 56 For information about The location of the fan connectors The signal names of the processor fan connector The signal names of the chassis fan connectors 44 Product Description 1.10.2.3 LAN Wake Capabilities CAUTION For LAN wake capabilities, the +5 V standby line for the power supply must be capable of providing adequate +5 V standby current. Failure to provide adequate standby current when implementing LAN wake capabilities can damage the power supply. LAN wake capabilities enable remote wake-up of the computer through a network. The LAN subsystem PCI bus network adapter monitors network traffic at the Media Independent Interface. Upon detecting a Magic Packet* frame, the LAN subsystem asserts a wake-up signal that powers up the computer. Depending on the LAN implementation, the board supports LAN wake capabilities with ACPI in the following ways: * * The PCI bus PME# signal for PCI 2.3 compliant LAN designs The onboard LAN subsystem 1.10.2.4 Instantly Available PC Technology CAUTION For Instantly Available PC technology, the +5 V standby line for the power supply must be capable of providing adequate +5 V standby current. Failure to provide adequate standby current when implementing Instantly Available PC technology can damage the power supply. Instantly Available PC technology enables the board to enter the ACPI S3 (Suspend-toRAM) sleep-state. While in the S3 sleep-state, the computer will appear to be off (the power supply is off, and the front panel LED is amber if dual colored, or off if single colored.) When signaled by a wake-up device or event, the system quickly returns to its last known wake state. Table 14 on page 43 lists the devices and events that can wake the computer from the S3 state. The board supports the PCI Bus Power Management Interface Specification. Add-in boards that also support this specification can participate in power management and can be used to wake the computer. The use of Instantly Available PC technology requires operating system support and PCI 2.3 compliant add-in cards and drivers. 1.10.2.5 * * * Resume on Ring The operation of Resume on Ring can be summarized as follows: Resumes operation from ACPI S1 or S3 states Detects incoming call similarly for external and internal modems Requires modem interrupt be unmasked for correct operation 1.10.2.6 Wake from USB USB bus activity wakes the computer from ACPI S1 or S3 states. 45 Intel Desktop Board D865GSA Technical Product Specification NOTE Wake from USB requires the use of a USB peripheral that supports Wake from USB. 1.10.2.7 Wake from PS/2 Devices PS/2 device activity wakes the computer from an ACPI S1 or S3 state. 1.10.2.8 PME# Signal Wake-up Support When the PME# signal on the PCI bus is asserted, the computer wakes from an ACPI S1, S3, S4, or S5 state (with Wake on PME enabled in BIOS) 1.10.2.9 +5 V Standby Power Indicator LED The +5 V standby power indicator LED shows that power is still present even when the computer appears to be off. Figure 9 shows the location of the standby power indicator LED. CAUTION If AC power has been switched off and the standby power indicator is still lit, disconnect the power cord before installing or removing any devices connected to the board. Failure to do so could damage the board and any attached devices. D23 OM18300 Figure 9.

The PCI specification specifies how interrupts can be shared between devices attached to the PCI bus. In most cases, the small amount of latency added by interrupt sharing does not affect the operation or throughput of the devices. In some special cases where maximum performance is needed from a device, a PCI device should not share an interrupt with other PCI devices. Use the following information to avoid sharing an interrupt with a PCI add-in card. PCI devices are categorized as follows to specify their interrupt grouping: * INTA: By default, all add-in cards that require only one interrupt are in this category. For almost all cards that require more than one interrupt, the first interrupt on the card is also classified as INTA. INTB: Generally, the second interrupt on add-in cards that require two or more interrupts is classified as INTB. (This is not an absolute requirement.) INTC and INTD: Generally, a third interrupt on add-in cards is classified as INTC and a fourth interrupt is classified as INTD. * * The ICH5 has eight Programmable Interrupt Request (PIRQ) input signals. All PCI interrupt sources either onboard or from a PCI add-in card connect to one of these PIRQ signals. Some PCI interrupt sources are electrically tied together on the board and therefore share the same interrupt. Table 20 shows an example of how the PIRQ signals are routed. For example, using Table 20 as a reference, assume an add-in card using INTA is plugged into PCI bus connector 3. In PCI bus connector 3, INTA is connected to PIRQB, which is already connected to the ICH5 audio controller. The add-in card in PCI bus connector 3 now shares an interrupt with the onboard interrupt source. 51 Intel Desktop Board D865GSA Technical Product Specification Table 20. PCI Interrupt Routing Map ICH5 PIRQ Signal Name PCI Interrupt Source SMBus controller AC '97 ICH5 Audio ICH5 LAN PCI bus connector 1 PCI bus connector 2 PCI bus connector 3 INTD INTA INTB INTC PIRQA PIRQB INTB INTB INTA INTD INTC INTA INTB INTB INTA INTC INTD PIRQC PIRQD PIRQE PIRQF PIRQG PIRQH NOTE In PIC mode, the ICH5 can connect each PIRQ line internally to one of the IRQ signals (3, 4, 5, 6, 7, 9, 10, 11, 12, 14, and 15). Typically, a device that does not share a PIRQ line will have a unique interrupt. However, in certain interrupt-constrained situations, it is possible for two or more of the PIRQ lines to be connected to the same IRQ signal. Refer to Table 18 for the allocation of PIRQ lines to IRQ signals in APIC mode. PCI interrupt assignments to USB ports and Serial ATA ports are dynamic. 2.7 Connectors CAUTION Only the following connectors have overcurrent protection: Back panel and front panel USB, PS/2, and VGA. The other internal connectors are not overcurrent protected and should connect only to devices inside the computer's chassis, such as fans and internal peripherals. Do not use these connectors to power devices external to the computer's chassis. A fault in the load presented by the external devices could cause damage to the computer, the power cable, and the external devices themselves. This section describes the board's connectors. The connectors can be divided into these groups: * * Back panel I/O connectors (see page 53) Component-side connectors (see page 54) 52 Technical Reference 2.7.1 Back Panel Connectors Figure 10 shows the location of the back panel connectors.

Figure 15. Board Dimensions 62 Technical Reference 2.9.2 I/O Shield The back panel I/O shield for the board must meet specific dimension and material requirements. Systems based on this board need the back panel I/O shield to pass certification testing. Figure 16 shows the I/O shield. In order to provide the required dimensions, the figure shows only the metal shield; the plastic face plate is not shown. Dimensions are given in millimeters. The figure indicates the position of each cutout. Additional design considerations for I/O shields relative to chassis requirements are described in the ATX specification.

This data is based on a DC analysis of all active components within the board that impact its power delivery subsystems. The analysis does not include PCI add-in cards. Minimum values assume a light load placed on the board that is similar to an environment with no applications running and no USB current draw. Maximum values assume a load placed on the board that is similar to a heavy gaming environment with a 500 mA current draw per USB port. These calculations are not based on specific processor values or memory configurations but are based on the minimum and maximum current draw possible from the board's power delivery subsystems to the processor, memory, and USB ports. Use the datasheets for add-in cards, such as PCI, to determine the overall system power requirements. The selection of a power supply at the system level is dependent on the system's usage model and not necessarily tied to a particular processor speed. Table 34. DC Loading Characteristics DC Current at: Mode Minimum loading Maximum loading DC Power 72.15 W 135.53 W +3.3 V 6.6 A 7.0 A +5 V 0.4 A 4.7 A +12 V 3.7A 7.0 A -12 V 0.01 A 0.01 A +5 VSB 0.05 A 0.05 A 2.10.2 Fan Connector Current Capability CAUTION The processor fan must be connected to the processor fan connector, not to a chassis fan connector. Connecting the processor fan to a chassis fan connector may result in onboard component damage that will halt fan operation. Table 35 lists the current capability of the fan connectors. Table 35. Fan Connector Current Capability Fan Connector Processor fan Front chassis fan Rear chassis fan Maximum Available Current 2.0 A 1.5 A 1.5 A 2.10.3 Add-in Board Considerations The board is designed to provide 2 A (average) of +5 V current for each add-in board. The total +5 V current draw for add-in boards for a fully loaded board (all three expansion slots and the AGP connector filled) must not exceed 8 A. 64 Technical Reference 2.10.4 Power Supply Considerations CAUTION The +5 V standby line for the power supply must be capable of providing adequate +5 V standby current. Failure to do so can damage the power supply. The total amount of standby current required depends on the wake devices supported and manufacturing options. System integrators should refer to the power usage values listed in Table 34 when selecting a power supply for use with the board. Additional power required will depend on configurations chosen by the integrator. The power supply must comply with the indicated sections of the ATX form factor specification. * The potential relation between 3.3 VDC and +5 VDC power rails * The current capability of the +5 VSB line * All timing parameters * All voltage tolerances 65 Intel Desktop Board D865GSA Technical Product Specification 2.11 Thermal Considerations CAUTION A chassis with a maximum internal ambient temperature of 38 oC at the processor fan inlet is a requirement. Use a processor heatsink that provides omni-directional airflow (similar to the type shown in Figure 17) to maintain required airflow across the processor voltage regulator area. OM16996 Figure 17. Processor Heatsink for Omni-directional Airflow CAUTION Failure to ensure appropriate airflow may result in reduced performance of both the processor and/or voltage regulator or, in some instances, damage to the board. For a list of chassis that have been tested with Intel desktop boards please refer to the following website: http://developer.intel.com/design/motherbd/cooling.htm All responsibility for determining the adequacy of any thermal or system design remains solely with the reader. Intel makes no warranties or representations that merely following the instructions presented in this document will result in a system with adequate thermal performance. CAUTION Ensure that the ambient temperature does not exceed the board's maximum operating temperature. Failure to do so could cause components to exceed their maximum case temperature and malfunction. For information about the maximum operating temperature, see the environmental specifications in Section 2.13. 66 Technical Reference CAUTION Ensure that proper airflow is maintained in the processor voltage regulator circuit. Failure to do so may result in damage to the voltage regulator circuit. The processor voltage regulator area (item A in Figure 18) can reach a temperature of up to 85 oC in an open chassis. Figure 18 shows the locations of the localized high temperature zones.

The FWH contains the BIOS Setup program, POST, the PCI auto-configuration utility, and Plug and Play support. The BIOS displays a message during POST identifying the type of BIOS and a revision code. The initial production BIOSs are identified as SA86510A.86A. When the BIOS Setup configuration jumper is set to configure mode and the computer is powered-up, the BIOS compares the CPU version and the microcode version in the BIOS and reports if the two match. The BIOS Setup program can be used to view and change the BIOS settings for the computer. The BIOS Setup program is accessed by pressing the NOTE The maintenance menu is displayed only when the board is in configure mode. Section 2.8 on page 61 shows how to put the board in configure mode. 77 Intel Desktop Board D865GSA Technical Product Specification Table 42 lists the BIOS Setup program menu features. Table 42.

PCI devices may be onboard or add-in cards. Autoconfiguration lets a user insert or remove PCI cards without having to configure the system. When a user turns on the system after adding a PCI card, the BIOS automatically configures interrupts, the I/O space, and other system resources. Any interrupts set to Available in Setup are considered to be available for use by the add-in card. 78 BIOS Setup Program 3.3.2 PCI IDE Support If you select Auto in the BIOS Setup program, the BIOS automatically sets up the PCI IDE connector with independent I/O channel support. The IDE interface supports hard drives up to ATA-66/100 and recognizes any ATAPI compliant devices, including CD-ROM drives, tape drives, and Ultra DMA drives. The BIOS determines the capabilities of each drive and configures them to optimize capacity and performance. To take advantage of the high capacities typically available today, hard drives are automatically configured for Logical Block Addressing (LBA) and to PIO Mode 3 or 4, depending on the capability of the drive. You can override the auto-configuration options by specifying manual configuration in the BIOS Setup program. To use ATA-66/100 features the following items are required: * * * An ATA-66/100 peripheral device An ATA-66/100 compatible cable ATA-66/100 operating system device drivers NOTE Do not connect an ATA device as a slave on the same IDE cable as an ATAPI master device. For example, do not connect an ATA hard drive as a slave to an ATAPI CD-ROM drive. 3.4 System Management BIOS (SMBIOS) SMBIOS is a Desktop Management Interface (DMI) compliant method for managing computers in a managed network. The main component of SMBIOS is the Management Information Format (MIF) database, which contains information about the computing system and its components. Using SMBIOS, a system administrator can obtain the system types, capabilities, operational status, and installation dates for system components. The MIF database defines the data and provides the method for accessing this information. The BIOS enables applications such as third-party management software to use SMBIOS. The BIOS stores and reports the following SMBIOS information: * * * * BIOS data, such as the BIOS revision level Fixed-system data, such as peripherals, serial numbers, and asset tags Resource data, such as memory size, cache size, and processor speed Dynamic data, such as event detection and error logging Non-Plug and Play operating systems, such as Windows NT*, require an additional interface for obtaining the SMBIOS information. The BIOS supports an SMBIOS table interface for such operating systems. Using this support, an SMBIOS service-level application running on a non-Plug and Play operating system can obtain the SMBIOS information. 79 Intel Desktop Board D865GSA Technical Product Specification 3.5 Legacy USB Support Legacy USB support enables USB devices to be used even when the operating system's USB drivers are not yet available. Legacy USB support is used to access the BIOS Setup program, and to install an operating system that supports USB. By default, Legacy USB support is set to Enabled. Legacy USB support operates as follows: 1. When you apply power to the computer, legacy support is disabled. 2. POST begins. 3. Legacy USB support is enabled by the BIOS allowing you to use a USB keyboard to enter and configure the BIOS Setup program and the maintenance menu. 4. POST completes. 5. The operating system loads. While the operating system is loading, USB keyboards and mice are recognized and may be used to configure the operating system. (Keyboards and mice are not recognized during this period if Legacy USB support was set to Disabled in the BIOS Setup program.) 6. After the operating system loads the USB drivers, all legacy and non-legacy USB devices are recognized by the operating system, and Legacy USB support from the BIOS is no longer used. To install an operating system that supports USB, verify that Legacy USB support in the BIOS Setup program is set to Enabled and follow the operating system's installation instructions. 3.6 * BIOS Updates Intel(R) Express BIOS Update utility, which enables automated updating while in the Windows environment. Using this utility, the BIOS can be updated from a file on a hard disk, a 1.44 MB diskette, or a CD-ROM, or from the file location on the Web. Intel(R) Flash Memory Update Utility, which requires creation of a boot diskette and manual rebooting of the system. Using this utility, the BIOS can be updated from a file on a 1.44 MB diskette (from a legacy diskette drive or an LS-120 diskette drive) or a CD-ROM. The BIOS can be updated using either of the following utilities, which are available on the Intel World Wide Web site: * Both utilities verify that the updated BIOS matches the target system to prevent accidentally installing an incompatible BIOS. NOTE Review the instructions distributed with the upgrade utility before attempting a BIOS update. For information about The Intel World Wide Web site Refer to Section 1.2, page 15 80 BIOS Setup Program 3.6.1 Language Support The BIOS Setup program and help messages are supported in US English. Additional languages are available in the Integrator's Toolkit utility. Check the Intel website for details. 3.6.2 Custom Splash Screen During POST, an Intel(R) splash screen is displayed by default. This splash screen can be augmented with a custom splash screen. The Integrator's Toolkit that is available from Intel can be used to create a custom splash screen. NOTE If you add a custom splash screen, it will share space with the Intel branded logo. For information about The Intel World Wide Web site Refer to Section 1.2, page 15 3.7 Boot Options In the BIOS Setup program, the user can choose to boot from a diskette drive, hard drives, CD-ROM, or the network. The default setting is for the diskette drive to be the first boot device, the hard drive second, and the ATAPI CD-ROM third. The fourth device is disabled. 3.7.1 CD-ROM Boot Booting from CD-ROM is supported in compliance to the El Torito bootable CD-ROM format specification. Under the Boot menu in the BIOS Setup program, ATAPI CD-ROM is listed as a boot device. Boot devices are defined in priority order. Accordingly, if there is not a bootable CD in the CD-ROM drive, the system will attempt to boot from the next defined drive. 3.7.2 Network Boot The network can be selected as a boot device. This selection allows booting from the onboard LAN or a network add-in card with a remote boot ROM installed. Pressing the 81 Intel Desktop Board D865GSA Technical Product Specification 3.7.3 Booting Without Attached Devices For use in embedded applications, the BIOS has been designed so that after passing the POST, the operating system loader is invoked even if the following devices are not present: * * * Video adapter Keyboard Mouse 3.7.4 Changing the Default Boot Device During POST Pressing the Boot Device Menu Function Keys <> or <> Description Selects a default boot device Exits the menu, saves changes, and boots from the selected device Exits the menu without saving changes 3.8 Fast Booting Systems with Intel(R) Rapid BIOS Boot Selecting and configuring peripherals properly Using an optimized BIOS, such as the Intel(R) Rapid BIOS These factors affect system boot speed: * * 3.8.1 * * * Peripheral Selection and Configuration Choose a hard drive with parameters such as "power-up to data ready" less than eight seconds, that minimize hard drive startup delays. Select a CD-ROM drive with a fast initialization rate. This rate can influence POST execution time. Eliminate unnecessary add-in adapter features, such as logo displays, screen repaints, or mode changes in POST. These features may add time to the boot process. Try different monitors. Some monitors initialize and communicate with the BIOS more quickly, which enables the system to boot more quickly. The following techniques help improve system boot speed: * 82 BIOS Setup Program 3.8.2 Intel Rapid BIOS Boot Use of the following BIOS Setup program settings reduces the POST execution time. In the Boot Menu: * Set the hard disk drive as the first boot device. As a result, the POST does not first seek a diskette drive, which saves about one second from the POST execution time. Disable Quiet Boot, which eliminates display of the logo splash screen. This could save several seconds of painting complex graphic images and changing video modes. Enable Intel Rapid BIOS Boot. This feature bypasses memory count and the search for a diskette drive. * * In the Peripheral Configuration submenu, disable the LAN device if it will not be used. This can reduce up to four seconds of option ROM boot time. NOTE It is possible to optimize the boot process to the point where the system boots so quickly that the Intel logo screen (or a custom logo splash screen) will not be seen. Monitors and hard disk drives with minimum initialization times can also contribute to a boot time that might be so fast that necessary logo screens and POST messages cannot be seen. This boot time may be so fast that some drives might be not be initialized at all. If this condition should occur, it is possible to introduce a programmable delay ranging from three to 30 seconds (using the Hard Disk Pre-Delay feature of the Advanced Menu in the Drive Configuration Submenu of the BIOS Setup program). 83 Intel Desktop Board D865GSA Technical Product Specification 3.9 BIOS Security Features The BIOS includes security features that restrict access to the BIOS Setup program and who can boot the computer. A supervisor password and a user password can be set for the BIOS Setup program and for booting the computer, with the following restrictions: * * * * The supervisor password gives unrestricted access to view and change all the Setup options in the BIOS Setup program. This is the supervisor mode. The user password gives restricted access to view and change Setup options in the BIOS Setup program. This is the user mode. If only the supervisor password is set, pressing the * * * Table 45 shows the effects of setting the supervisor password and user password. This table is for reference only and is not displayed on the screen. Table 45. Supervisor and User Password Functions Password Set Neither Supervisor Mode Can change all options (Note) Password to Password Enter Setup During Boot User Mode Can change all options (Note) Setup Options None None Supervisor None None Supervisor only Can change all options User only N/A Supervisor Password Can change a limited number of options Can change all options Enter Password Clear User Password User Supervisor or user User Supervisor or user Supervisor and Can change all user set options Note: Supervisor Password Can change a limited number Enter Password of options If no password is set, any user can change all Setup options. 84 4 Error Messages and Beep Codes What This Chapter Contains 4.1 4.2 4.3 4.4 4.5 BIOS Error Messages ..................................................................................85 Port 80h POST Codes ..................................................................................86 Bus Initialization Checkpoints .......................................................................91 Speaker ...................................................................................................92 BIOS Beep Codes .......................................................................................92 4.1 BIOS Error Messages Table 46 lists the error messages and provides a brief description of each.

The system should be powered down and the jumper removed. CMOS is ignored and NVRAM is cleared. User must enter Setup. 4.2 Port 80h POST Codes During the POST, the BIOS generates diagnostic progress codes (POST-codes) to I/O port 80h. If the POST fails, execution stops and the last POST code generated is left at port 80h. This code is useful for determining the point where an error occurred. Displaying the POST-codes requires a PCI bus add-in card, often called a POST card. The POST card can decode the port and display the contents on a medium such as a seven-segment display. NOTE The POST card must be installed in PCI bus connector 1. The tables below offer descriptions of the POST codes generated by the BIOS. Table 47 defines the uncompressed INIT code checkpoints, Table 48 describes the boot block recovery code checkpoints, and Table 49 lists the runtime code uncompressed in F000 shadow RAM. Some codes are repeated in the tables because that code applies to more than one operation. 86 Error Messages and Beep Codes Table 47.

Table 50 describes the bus initialization checkpoints. Table 50. Bus Initialization Checkpoints Checkpoint 2A 38 39 95 Description Different buses init (system, static, and output devices) to start if present. Different buses init (input, IPL, and general devices) to start if present. Display different buses initialization error messages. Init of different buses optional ROMs from C800 to start. While control is inside the different bus routines, additional checkpoints are output to port 80h as WORD to identify the routines under execution. In these WORD checkpoints, the low byte of the checkpoint is the system BIOS checkpoint from which the control is passed to the different bus routines. The high byte of the checkpoint is the indication of which routine is being executed in the different buses. Table 51 describes the upper nibble of the high byte and indicates the function that is being executed. Table 51. Upper Nibble High Byte Functions Value 0 1 2 3 4 5 6 7 Description func#0, disable all devices on the bus concerned. func#1, static devices init on the bus concerned. func#2, output device init on the bus concerned. func#3, input device init on the bus concerned. func#4, IPL device init on the bus concerned. func#5, general device init on the bus concerned. func#6, error reporting for the bus concerned. func#7, add-on ROM init for all buses. 91 Intel Desktop Board D865GSA Technical Product Specification Table 52 describes the lower nibble of the high byte and indicates the bus on which the routines are being executed. Table 52. Lower Nibble High Byte Functions Value 0 1 2 3 4 5 Description Generic DIM (Device Initialization Manager) On-board System devices ISA devices EISA devices ISA PnP devices PCI devices 4.4 Speaker A 47 inductive speaker is mounted on the board. The speaker provides audible error code (beep code) information during POST. For information about The location of the onboard speaker Refer to Figure 1, on page 12 4.5 BIOS Beep Codes Whenever a recoverable error occurs during POST, the BIOS displays an error message describing the problem (see Table 53). The BIOS also issues a beep code (one long tone followed by two short tones) during POST if the video configuration fails (a faulty video card or no card installed) or if an external ROM module does not properly checksum to zero. An external ROM module (for example, a video BIOS) can also issue audible errors, usually consisting of one long tone followed by a series of short tones. For more information on the beep codes issued, check the documentation for that external device. There are several POST routines that issue a POST terminal error and shut down the system if they fail. Before shutting down the system, the terminal-error handler issues a beep code signifying the test point error, writes the error to I/O port 80h, attempts to initialize the video and writes the error in the upper left corner of the screen (using both monochrome and color adapters). If POST completes normally, the BIOS issues one short beep before passing control to the operating system. 92 Error Messages and Beep Codes Table 53.
