BIOS Recovery Instructions
If the BIOS language update procedure fails, leaving your BIOS in an unusable
and unrecoverable state, perform the following steps and then retry the BIOS
language update.
Because of the small amount of code available in the non-erasable boot block
area, video is not available to direct the recovery procedure. The procedure can
be monitored by listening to the speaker and looking at the diskette drive LED.
When the system gives a continuous series of short beeps and the diskette drive
LED is lit, the system is copying the recovery code into the FLASH. As soon as
the system gives a long beep, the recovery is complete (takes approximately 75
seconds).
1. If the BIOS language update procedure fails while using Multi-Language
BIOS FLASH diskette 1 of 2, insert Multi-Language BIOS FLASH diskette
2 of 2 into floppy disk drive A. Otherwise, keep diskette 2 of 2 in floppy
disk drive A.
2. Power off the system and turn the power back on.
3. When the system beeps and the diskette drive LED is lit, the system is
copying the recovery code into the FLASH. As soon as the system emits a
long beep, the recovery is complete.
4. Power off the system.
5. Remove the Multi-Language BIOS FLASH diskette 2 of 2 from floppy disk
drive A. Proceed to the previous procedure to change the BIOS Setup
language.
