BIOS system recovery for DP systems
The dual-processor based platforms have a 4 MB flash part that includes a Primary and
Secondary flash bank. During the BIOS update process, if the BIOS gets corrupted, the
system will automatically switch from the Primary flash area to the secondary area during
the next boot. No other recovery action is needed.
If the payload does not boot or is corrupted, change the recovery jumper and boot from the
other bank. Now you can update with a new payload.
BIOS system recovery for UP systems
To recover from corrupt BIOS on a UP system, do the following:
1. Make a DOS* bootable USB key. Place the contents of the latest production BIOS (R39
onwards) in the USB key which includes the DOS iFlash32.exe and the fv_main.fv.
2. Power off the system.
3. Plug in the USB key and remove jumper J1B3.
4. Power on the server, choose the USB disk as the boot device if required, the recovery
boot block in the BIOS will automatically boot using the fv_main.fv file and will boot to
the DOS image on the USB key.
5. Flash the production BIOS that you have in the USB using iFlash32.exe.
6. Remove the USB key.
7. Power off the server and replace the jumper back in its original position.
8. Power on the server and reboot the system.
