3.6 Recovering BIOS Data

Some types of failure can destroy the BIOS. For example, the data can be lost if a power outage occurs while the BIOS is being upgraded in flash memory. The BIOS can be recovered from either a 1.44 MB diskette (for recovery from an LS-120 diskette drive configured as an ATAPI removable IDE device) or from a CD-ROM (for use in an ATAPI CD-ROM drive) using the BIOS recovery mode. When recovering the BIOS, be aware of the following:

∙Recovery requires the use of bootable media in a bootable device.

∙Because of the small amount of code available in the nonerasable boot block area, there is no video support. You can only monitor this procedure by listening to the speaker or looking at the recovery drive LED.

∙Two beeps indicate the beginning of the BIOS recovery process.

∙Two beeps and the end of activity in the recovery drive indicate successful BIOS recovery.

∙A series of continuous beeps indicates a failed BIOS recovery.

BIOS recovery media can be either a 1.44 MB diskette or a CD-ROM. The recovery media must be bootable and it must contain the BIOS update files copied to it. BIOS upgrades and the Intel Flash Memory Upgrade utility are available from Intel Customer Support through the Intel World Wide Web site.

✏NOTE

BIOS recovery cannot be accomplished using non-SPD DIMMs. SPD data structure is required for the recovery process.

✏NOTE

If the computer is configured to boot from an LS-120 diskette (in the Boot menu), the BIOS recovery diskette must be a standard 1.44 MB diskette not a 120 MB diskette.
