Use a shielded cable that meets the requirements for a full-speed USB device. The desktop board supports up to eight USB 2.0 ports via ICH6; four ports routed to the back panel and four routed to two internal USB 2.0 headers. USB 2.0 ports are backward compatible with USB 1.1 devices. USB 1.1 devices will function normally at USB 1.1 speeds. USB 2.0 support requires both an operating system and drivers that fully support USB 2.0 transfer rates. Disabling Hi-Speed USB in BIOS reverts all USB 2.0 ports to USB 1.1 operation. This may be required to accommodate operating systems that do not support USB 2.0. 21 Intel Desktop Board D915GEV/D915GUX/D915GAV/D915GAG Product Guide Enhanced IDE Interface The ICH6's IDE interface handles the exchange of information between the processor and peripheral devices like hard disks, CD-ROM drives, and Iomega Zip* drives inside the computer. The interface supports: · Up to two IDE devices (such as hard drives) · ATAPI-style devices (such as CD-ROM drives) · Older PIO Mode devices · Ultra DMA-33 and ATA-66/100 protocols · Laser Servo (LS-120) drives Serial ATA The desktop boards support four Serial ATA channels via ICH6, connecting one device per channel. Expandability The desktop boards support the following: · Desktop boards D915GAV and D915GEV One PCI Express x16 add-in card Two PCI Express x1 add-in cards Four PCI add-in cards · Desktop boards D915GAG and D915GUX: One PCI Express x16 add-in card One PCI Express x1 add-in card Two PCI add-in cards Related Links: For information about installing the PCI Express x16 card, see page 41 in Chapter 2. BIOS The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the PCI/PCI Express and IDE auto-configuration utilities, and the video BIOS. The BIOS is stored in the Firmware Hub. The BIOS can be updated by following the instructions on page 59 in Chapter 3. Serial ATA and IDE Auto Configuration If you install a Serial ATA or IDE device (such as a hard drive) in your computer, the autoconfiguration utility in the BIOS automatically detects and configures the device for your computer. You do not need to run the BIOS Setup program after installing a Serial ATA or IDE device. You can override the auto-configuration options by specifying manual configuration in the BIOS Setup program. 22 Desktop Board Features PCI and PCI Express Auto Configuration If you install a PCI/PCI Express add-in card in your computer, the PCI/PCI Express autoconfiguration utility in the BIOS automatically detects and configures the resources (IRQs, DMA channels, and I/O space) for that add-in card. You do not need to run the BIOS Setup program after you install a PCI/PCI Express add-in card. Security Passwords The BIOS includes security features that restrict whether the BIOS Setup program can be accessed and who can boot the computer. A supervisor password and a user password can be set for the BIOS Setup and for booting the computer, with the following restrictions: · · · The supervisor password gives unrestricted access to view and change all Setup options. If only the supervisor password is set, pressing at the password prompt of Setup gives the user restricted access to Setup. If both the supervisor and user passwords are set, you must enter either the supervisor password or the user password to access Setup. Setup options are then available for viewing and changing depending on whether the supervisor or user password was entered. Setting a user password restricts who can boot the computer. The password prompt is displayed before the computer is booted. If only the supervisor password is set, the computer boots without asking for a password. If both passwords are set, you can enter either password to boot the computer. 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 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. 23 Intel Desktop Board D915GEV/D915GUX/D915GAV/D915GAG Product Guide 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. NOTE 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. Suspend to RAM (Instantly Available PC Technology) CAUTION For Instantly Available PC technology, the 5 V standby line for the power supply must be capable of delivering adequate +5 V standby current. Failure to provide adequate standby current when using this feature can damage the power supply and/or effect ACPI S3 sleep state functionality. CAUTION Power supplies used with this desktop board must be able to provide enough standby current to support the standard Instantly Available (ACPI S3 sleep state) configuration. If the standby current necessary to support multiple wake events from the PCI and/or USB buses exceeds power supply capacity, the desktop board may lose register settings stored in memory. 24 Desktop Board Features Instantly Available PC technology enables the board to enter the ACPI S3 (Suspend-to-RAM) sleep state. While in the S3 sleep state, the computer will appear to be off. When signaled by a wake-up device or event, the system quickly returns to its last known awake state. The desktop board's standby power indicator, shown in Figure 4, is lit when there is standby power to the system. This includes the memory modules and PCI bus connectors, even when the computer appears to be off. If the system has a dual-colored power LED on the front panel, the sleep state is indicated by the LED turning amber. OM16879 Figure 4.
