Recovering the BIOS
In the rare event that the BIOS becomes damaged, a recovery process needs to be followed to return
the system to service. Two methods are available to recover the BIOS: automatically with the crisis
recovery diskette, and manually by moving a jumper on the system board. These methods are
described below.
✏
NOTE
BIOS recovery is the mode of last resort, used only when the main system
BIOS will not come up.
Recovering the BIOS with the Crisis Recovery Diskette
Automatically Recovering the BIOS
If a ROM checksum error occurs during POST, the system will automatically enter BIOS recovery
mode. This is indicated by system beeping with one long beep followed by two short beeps. When
you hear this beep pattern, use the following steps to initiate an automatic recovery:
1. Insert the Crisis Recovery Diskette into the A: diskette drive.
2. A blue screen will be displayed and the recovery process will automatically run. The system
will continue to beep throughout the recovery process.
3. A series of three beeps and no disk access signals the need to insert disk two.
4. When the beeping stops and disk access stops on disk two the recovery process is complete.
5. Remove disk two.
6. Power down and unplug the system from the AC power source.
7. Plug the system into the AC power source and power it up to confirm that the recovery was
successful.
