Chassis Intrusion

The board supports a chassis security feature that detects if the chassis cover has been removed. The security feature uses a mechanical switch on the chassis that can be connected to the chassis intrusion header on the desktop board. See Figure 22 on page 44 for the location of the chassis intrusion header.
Power Management Features
Power management is implemented at several levels, including: Advanced Configuration and Power Interface (ACPI) Hardware support: Power connectors Fan connectors Suspend to RAM (Instantly Available PC technology) Resume on Ring Wake from USB Wake from PS/2 keyboard/mouse PME# wakeup support
ACPI gives the operating system direct control over the power management and Plug and Play functions of a computer. The use of ACPI with the desktop board requires an operating system that provides full ACPI support.

Power Connectors

The desktop boards have three power connectors. See Figure 25 on page 49 and Figure 26 on page 50 for the location of the power connectors.

Fan Connectors

The desktop boards have a 4-pin processor fan header. Desktop boards D915GAV and D915GEV have three chassis fan headers. Desktop boards D915GAG and D915GUX have two chassis fan headers. See Figure 24 on page 48 for the location of the fan headers.
Fan Speed Control (Intel Precision Cooling Technology)
Intel Precision Cooling Technology automatically adjusts the processor fan speed based on the processor thermal diode temperature and adjusts the chassis fan speeds depending on the system temperature. System fan noise may be reduced by operating controlled chassis and processor fans at the minimum necessary speeds.
Not all chassis fan headers on desktop boards D915GEV and D915GAV are controlled. Refer to Table 3 on page 13 to identify controlled chassis fan headers. The processor and chassis fan speed control features can be disabled independently through the desktop board BIOS. Disabling the processor fan speed control will result in the fan operating at full speed if it is not a self controlled fan. It is recommended that processor fan speed control remain enabled (default BIOS setting) when using the processor fan heat-sink included with Intel boxed processors. Disabling the chassis fan speed control results in chassis fans always operating at full speed. The chassis fan speed control feature should be disabled if a self-controlled chassis fan is attached to any controlled chassis fan header. The overall system noise reduction will vary based on system configuration and environment.

Only qualified technical personnel should do this procedure. Disconnect the computer from its power source before performing the procedures described here. Failure to disconnect the power before you open the computer can result in personal injury or equipment damage.
Refer to Appendix B for regulatory requirements. Refer to your chassis manual for instructions on installing and removing the desktop board. Figure 6 shows the location of the 11 mounting holes for desktop boards D915GAV and D915GEV. Desktop boards D915GAG and D916GUX have eight mounting holes.

Replacing the 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. 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 30 on page 58 shows the location of the battery.
Risk of explosion if the battery is replaced with an incorrect type. Batteries should be recycled where possible. Disposal of used batteries must be in accordance with local environmental regulations.

2.1 Introduction

Sections 2.2 - 2.6 contain several standalone tables. Table 10 describes the system memory map, Table 11 lists the DMA channels, Table 12 shows the I/O map, Table 13 defines the PCI Conventional bus configuration space map, and Table 14 describes the interrupts. The remaining sections in this chapter are introduced by text found with their respective section headings.

2.2 Memory Resources

2.2.1 Addressable Memory
The board utilizes 4 GB of addressable system memory. Typically the address space that is allocated for PCI Conventional bus add-in cards, PCI Express configuration space, BIOS (firmware hub), and chipset overhead resides above the top of DRAM (total system memory). On a system that has 4 GB of system memory installed, it is not possible to use all of the installed memory due to system address space being allocated for other system critical functions. These functions include the following: BIOS/firmware hub (2 MB) Local APIC (19 MB) Digital Media Interface (40 MB) Front side bus interrupts (17 MB) PCI Express configuration space (256 MB) MCH base address registers, internal graphics ranges, PCI Express ports (up to 512 MB)
Memory-mapped I/O that is dynamically allocated for PCI Conventional and PCI Express add-in cards
The amount of installed memory that can be used will vary based on add-in cards and BIOS settings. Figure 15 shows a schematic of the system memory map. All installed system memory can be used when there is no overlap of system addresses.
4 GB Top of System Address Space FLASH APIC Reserved PCI Memory Range contains PCI, chipsets, Direct Media Interface (DMI), and ICH ranges (approximately 750 MB) Top of usable DRAM (memory visible to the operating system) ~20 MB

2.12 Thermal Considerations
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 (as shown in Figure 24) to maintain required airflow across the processor voltage regulator area.

OM16996

Figure 24. Processor Heatsink Airflow
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.
Ensure that the ambient temperature does not exceed the boards 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 2.14.
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 25) can reach a temperature of up to 85 oC in an open chassis. Figure 25 shows the locations of the localized high temperature zones.

3.6 BIOS Updates

The BIOS can be updated using either of the following utilities, which are available on the Intel World Wide Web site: Intel 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 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. Both utilities verify that the updated BIOS matches the target system to prevent accidentally installing an incompatible BIOS.
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 1.3, page 17

Language Support

The BIOS Setup program and help messages are supported in US English. Additional languages are available in the Integrators Toolkit utility. Check the Intel website for details.

Custom Splash Screen

During POST, an Intel splash screen is displayed by default. This splash screen can be augmented with a custom splash screen. The Integrators Toolkit that is available from Intel can be used to create a custom splash screen.
If you add a custom splash screen, it will share space with the Intel branded logo.

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.

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.

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 <F12> key during POST automatically forces booting from the LAN. To use this key during POST, the User Access Level in the BIOS Setup program's Security menu must be set to Full.
