Recovering an Interrupted BIOS Upgrade
If an interruption or error occurred as you were upgrading the
BIOS, follow these steps to recover your BIOS:
1.
Change the setting of jumper J12H1 to allow a flash recovery
of your BIOS. See Chapter 4 for instructions.
2.
Insert the bootable diskette containing the BIOS upgrade
and recovery utility and the new BIOS file in drive A.
3.
Turn on your system. You will not see any video display
during the rest of this procedure because of the small
amount of code available in the non-erasable boot block
area. Listen to your computer’s speaker and watch the
diskette drive access light (as described below) to monitor
the utility’s operation.
The system beeps once and the diskette drive LED lights up.
The recover operation is in progress. When it is finished
copying the recovery code, the system beeps twice and the
diskette drive access light goes out.
