Refer to "Additional Information and Software" for a link to the update software. Note: Before attempting a BIOS upgrade, review the instructions and release notes provided in the README file distributed with the BIOS image. Review also any release notes in the release notes file that accompany the new version of the BIOS. The release notes may contain critical information regarding jumper settings, specific fixes, or other information to complete the upgrade. Upgrading the BIOS Follow the instructions in the readme file that came with the BIOS upgrade. When the upgrade completes, remove the bootable media from which you performed the upgrade. Caution: Do not power down the system during the BIOS upgrade process! When the BIOS upgrade is completed, the system resets automatically. Note: You may encounter a CMOS Checksum error or other problems after reboot. If this happens, shut down the system and re-boot. CMOS checksum errors require that you enter Setup, check your settings, save your settings, and exit Setup.
