Processor heat sink fan will not turn
Connect the processor's 4-pin fan heatsink cable to the processor fan connector labeled CPU FAN.
Ensure that the 2x2 or 2x4 power supply cable (depending on desktop board model) is plugged into the 12V processor core voltage connector located near the processor socket on the desktop board.

Floppy drive or CD-ROM not detected during boot
If you make any hardware changes related to drives, such as adding/removing hard drives, floppy drives or CD-ROMs, the specified boot order may change.
Additionally, after you upgrade to a new BIOS or if you set the BIOS to factory defaults, your floppy drive or CD-ROM may not be detected in the desired boot order.
The boot order in the BIOS:
- Enter the BIOS Setup program by pressing the <F2> key after the power on self test (POST) memory test begins.
- Select the boot menu and then the boot device priority menu.
- Select first boot device, second boot device, etc.
- Save and exit [F10].

BIOS recovery
If you are sure that you have integrated the PC components correctly but the system is not booting properly, letting you enter the BIOS Setup, or reflash the BIOS, then you may need to perform a BIOS recovery. The recovery process requires the chassis to be opened to move the onboard BIOS Configuration Jumper.
For complete instructions, refer to Instructions for BIOS Recovery Update.

Desktop Board Resources not Recognized by Microsoft Windows*
Intel® Chipsets have several components that are newer and not necessarily enabled in the retail or OEM versions of Microsoft Windows Vista*, Microsoft Windows XP* or Microsoft Windows 2000*. You may need to install the INF chipset update utility and additional drivers in order for all the board features to work properly. See the System Setup by Operating System - Microsoft Windows 7*, Microsoft Windows Vista*, Microsoft Windows XP* or Microsoft Windows 2000* for assistance.

Enabling dual channel memory
Intel® Desktop Boards based on the Intel® 945 Express Chipset Family and later support dual channel memory. Dual channel memory configurations will provide increased performance over single channel configurations. Refer to Single / Dual Channel Memory for complete information on configuring dual channel memory mode.
