video support.
You 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
