In-Depth Information
In addition to moving the jumper, the recovery requires that either a floppy, optical, or
USB flash drive containing media with the BIOS image file is attached to the system and
properly configured. Most older motherboards only support recovery from a floppy drive,
whereas most newer boards support optical or USB.
Before beginning the recovery procedure, you need to download the proper recovery im-
age file for the motherboard you are recovering. Obviously, you need to do this using an-
other system if the system to be recovered is nonfunctional. The image file can be down-
loadable separately, or it can be part of an archive with other files, such as flash program-
ming tools and documentation. In this case you only need the actual image file; none of
the other programs or files will be used. You also need to ensure that either a working
floppy or optical drive is properly installed in the system.
To recover the BIOS using the floppy recovery method, perform the following steps:
1.
Copy only the proper recovery 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 offthe system and remove the BIOS configuration jumper to enable BIOS Re-
covery mode (refer to
Figure 5.7
).
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.
