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 configur-
ation jumper to enable normal operation.
You can use the optical or USB flash drive methods on newer motherboards that do not
have a built-in floppy controller or for which the recovery file won't fit on a 1.44MB
floppy. Although the drive can be virtually any type of CD or DVD optical drive, the
actual disc you use should be a CD-R or RW that is burned with the file and finalized
(closed). You can burn the disc using the built-in CD-burning software found in Windows
(XP or later), or you can use third-party software such as the free ImgBurn application
(

)
, which is more powerful, easier to use, and works with older ver-
sions of Windows.
To recover the BIOS using the optical drive method, perform the following steps:
1.
Burn and finalize a disc (preferably a CD) with a copy of the recovery image file.
2.
Place the disc in the primary optical drive of the system to be recovered.
3.
Power offthe system and remove the BIOS configuration jumper to enable BIOS Re-
covery mode.
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.

Note
A BIOS recovery may corrupt the BIOS Setup information stored in the CMOS RAM. If the
error message

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.
If your motherboard does not include a BIOS configuration jumper, there might still be a

floppy disk and flash it into the ROM if found. To perform a recovery, first download the
latest BIOS image file for the motherboard, copy the file to a blank formatted floppy, and
