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 updated in flash memory. The BIOS can be recovered from a
diskette using the BIOS recovery mode. When recovering the BIOS, be aware of the following:
• Because of the small amount of code available in the non-erasable boot block area, there is no
video support. The user can only monitor this procedure by listening to the speaker or looking
at the diskette drive LED.
• The recovery process may take several minutes; larger BIOS flash memory devices require
more time.
• Two beeps and the end of activity in the diskette drive indicate successful BIOS recovery.
• A series of continuous beeps indicates a failed BIOS recovery.
To create a BIOS recovery diskette, a bootable diskette must be created and the BIOS update files
copied to it. BIOS upgrades and the Intel Flash Memory Update Utility are available from Intel
Customer Support through the Intel World Wide Web site.

NOTE
Even if the computer is configured to boot from an LS-120 diskette (in the
Setup program’s Removable Devices submenu), the BIOS recovery diskette
must be a standard 1.44 MB diskette not a 120 MB diskette.
