Upgrading the BIOS
The upgrade utility allows you to upgrade the BIOS in the flash memory. To prepare to upgrade the BIOS, you need to record the current BIOS settings and download the BIOS image file to a temporary folder on your hard drive or a USB flash memory device.
To record the current BIOS settings:
1Run BIOS setup. See “Entering BIOS setup” on page 100.
2Write down the current settings in the Setup Utility.
To download the BIOS image file:
Download the image file to a temporary folder on your hard drive or a USB flash memory device.
Note: Review the instructions and release notes that are provided in the Readme file distributed with the BIOS image file before attempting a BIOS upgrade. The release notes contain critical information regarding jumper settings, specific fixes, or other information to complete the upgrade.
To upgrade the BIOS:
Follow the instructions in the Readme file that came with the BIOS upgrade. When the update completes, remove the bootable media from which you performed the upgrade.
Note: Do not power down the system during the BIOS update process. The system will reset automatically when the BIOS update process is completed. You may encounter a CMOS checksum error or other problem after reboot. It this happens, shut down the system and boot it again. CMOS checksum errors require that you enter Setup, check your settings, save your settings, and exit Setup.
