BIOS Recovery
While rare, there may be a time when the system BIOS becomes corrupted. If it
does, it’s usually because a BIOS update was interrupted.
To perform a BIOS Recovery, use the following procedure in conjunction with a
BIOS Recovery program. The program can be downloaded from the NEC CSD
BBS, ftp site, or website. The BIOS Recovery program must be downloaded to a
diskette, not to the hard drive. See Section 9 for downloading procedures.
