3.
Power off the system and remove the BIOS configuration jumper to enable BIOS Recovery
mode (refer to
Figure 5.5
)
.
4.
Power on the system; the recovery should begin automatically.
5.
The recovery should complete in 2 to 5 minutes, after which the system will remain running,
turn off automatically, or prompt you to turn it off manually.
6.
With the system powered off, restore the BIOS configuration jumper to enable normal
operation.
Note
A BIOS recovery may corrupt the BIOS Setup information stored in the CMOS RAM. If the
error message CMOS/GPNV Checksum Bad... Press F1 to Run SETUP appears during the first
boot after the update, press F1 to go into the BIOS Setup Utility, press F9 to load setup
defaults, and then press F10 to save and exit to correct the problem.
To recover the BIOS using the USB flash drive method, perform the following steps:
1.
Copy the BIOS image file to the root folder of a FAT-32 formatted USB flash drive.
2.
Plug the flash drive into a USB port of the system to be recovered.
3.
Power off the system and remove the BIOS configuration jumper to enable BIOS Recovery
mode (refer to
Figure 5.5
)
.
4.
Power on the system; the recovery should begin automatically.
5.
The recovery should complete in 2 to 5 minutes, after which the system will remain running,
turn off automatically, or prompt you to turn it off manually.
6.
With the system powered off, restore the BIOS configuration jumper to enable normal
operation.
To recover the BIOS using the floppy recovery method, perform the following steps:
1.
Copy the BIOS image file to a blank formatted floppy disk.
2.
Place the disk in the primary floppy drive attached to the system to be recovered.
3.
Power off the system and remove the BIOS configuration jumper to enable BIOS Recovery
mode (refer to
Figure 5.5
)
.
4.
Power on the system; the recovery should begin automatically. You should hear a beep at the
start and see activity on the floppy drive during the procedure.
5.
The recovery should complete in 2 to 5 minutes, after which the system will remain running,
power off automatically, or prompt you to turn it off manually.
6.
With the system powered off, remove the floppy disk, and restore the BIOS configuration
jumper to enable normal operation.
Because the procedure can vary for different motherboards, I recommend consulting the motherboard
manual as well as the BIOS update instructions to see if there is a flash recovery option, and exactly
how to use it.
With any of these procedures, wait at least several minutes after all disk and beeping activity stops
before restarting the system. When you power the system back on, the new BIOS should be installed
