Desktop Board Features IDE Auto Configuration If you install an IDE device (such as a hard drive) in your computer, the IDE auto-configuration 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 an IDE device. You can override the autoconfiguration options by specifying manual configuration in the BIOS Setup program.
Intel Desktop Boards D845GRG and D845GBV Product Guide 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. Instantly Available technology enables the board to enter the ACPI S3 (Suspend-to-RAM) sleep state.
Desktop Board Features CAUTION Power supplies used with this 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 Intel desktop board may lose register settings stored in memory.
Intel Desktop Boards D845GRG and D845GBV Product Guide Wake from PS/2 Keyboard/Mouse PS/2 keyboard/mouse activity wakes the computer from an ACPI S1 or S3 state. PME# Wakeup Support When the PME# signal on the PCI bus is asserted, the computer wakes from an ACPI S1, S3, or S5 state. Speaker A speaker is mounted on the desktop board. The speaker provides audible error code (beep code) information during the Power-On Self-Test (POST).

Intel Desktop Boards D845GRG and D845GBV Product Guide Installing the I/O Shield The Intel desktop board comes with an I/O shield. When installed in the chassis, the shield blocks radio frequency transmissions, protects internal components from dust and foreign objects, and promotes correct airflow within the chassis. Install the I/O shield before installing the desktop board in the chassis. Place the shield inside the chassis as shown in Figure 4.
Installing and Replacing Desktop Board Components Installing and Removing the Desktop Board Refer to your chassis manual for instructions on installing and removing the Intel desktop board. WARNING This procedure should be done only by qualified technical personnel. 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.
Intel Desktop Boards D845GRG and D845GBV Product Guide Installing and Removing a Processor Instructions on how to install the processor to the Intel desktop board are given below. Installing a Processor CAUTION Before installing or removing the processor, make sure that AC power has been removed by unplugging the power cord from the computer; the standby power LED should not be lit (see Figure 3 on page 18). Failure to do so could damage the processor and the board.
Installing and Replacing Desktop Board Components Connecting the Processor Fan Heat Sink Cable Connect the processor fan heat sink cable to the processor fan connector (see Figure 7). OM13599 Figure 7. Connecting the Processor Fan Heat Sink Cable to the Processor Fan Connector Removing the Processor For instruction on how to remove the processor fan heat sink and processor, refer to the processor installation manual or the Intel World Wide Web site at: http://support.intel.
Intel Desktop Boards D845GRG and D845GBV Product Guide Installing and Removing Memory CAUTION To be fully compliant with all applicable Intel SDRAM memory specifications, the boards require DIMMs that support the Serial Presence Detect (SPD) data structure. You can access the PC Serial Presence Detect Specification at: http://www.intel.com/technology/memory/pcsdram/spec/ Desktop Boards D845GRG2 and D845GBV have two 184-pin DIMM sockets arranged as banks 0 and 1, as shown in Figure 8.
Installing and Replacing Desktop Board Components 5. Make sure the clips at either end of the DIMM socket(s) are pushed outward to the open position. 6. Holding the DIMM by the edges, remove it from its anti-static package. 7. Position the DIMM above the socket. Align the two small notches in the bottom edge of the DIMM with the keys in the socket (see inset in Figure 8). 8. Insert the bottom edge of the DIMM into the socket. 9.
Intel Desktop Boards D845GRG and D845GBV Product Guide Removing the AGP Card Follow these instructions to remove the AGP card from the RM: 1. Remove the screw (B) that secures the card’s metal bracket (A) to the chassis back panel. 2. Push back on the RM lever (D), as shown in Figure 9, until the retention pin (C) completely clears the notch in the card. 3. Pull the card straight up (E). B E A C D OM10595 Figure 9.
Installing and Replacing Desktop Board Components ✏ 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. For correct function of the cable: • • Attach the cable end with the single connector to the Intel desktop board. Attach the cable end with the two closely spaced connectors to the drives. A B OM13608 Figure 10.
Intel Desktop Boards D845GRG and D845GBV Product Guide Connecting the Front Panel Header Before connecting the front panel header, observe the precautions in “Before You Begin” on page 21.

3 Updating the BIOS This chapter tells you how to update the BIOS by either using the Intel® Express BIOS Update utility or the Intel® Flash Memory Update Utility, and how to recover the BIOS if an update fails. Updating the BIOS with the Intel® Express BIOS Update Utility With the Intel Express BIOS Update utility you can update the system BIOS while in the Windows environment.
Intel Desktop Boards D845GRG and D845GBV Product Guide Updating the BIOS with the Intel® Flash Memory Update Utility With the Intel Flash Memory Update Utility you can update the system BIOS from a floppy disk or other bootable media. The utility available from the Web provides a simple method for creating a bootable flash memory update floppy that will automatically update your BIOS. Obtaining the BIOS Update File You can update to a new version of the BIOS by using the BIOS update file.
Updating the BIOS Recovering the BIOS It is unlikely that anything will interrupt the BIOS update; however, if an interruption occurs, the BIOS could be damaged. The following steps explain how to recover the BIOS if an update fails. The following procedure uses recovery mode for the Setup program. See page 30 for more information on Setup modes. ✏ NOTE Because of the small amount of code available in the boot block area, there is no video support.
