System BIOS (8650)
System BIOS
The system BIOS is stored in nonvolatile memory (NVRAM) in a flash EPROM
device. You can easily update the BIOS without replacing the device. The
two procedures are:
A BIOS update always updates Setup, the onboard Video BIOS, and the SCSI
BIOS. Language files will be overwritten by a BIOS update. If a custom
language file has been created for the system, you must flash in the custom
file again after updating the BIOS. The user binary area is untouched by a
system BIOS update.
When running FMUP in the interactive mode, you can do the following:
- Save: Take a mirror image copy of a given flash area and copy it
to a hard disk or diskette.
- Update: Take a file or files from a hard disk or diskette and
update them with the system's flash device.
- Verify: Compare an existing flash area against a file or files
on hard disk or diskette to verify that the versions are the same and
insure that the system has the correct BIOS version.
NOTE:
FMU must be run without the presence of a 386 control program (such as
Windows or EMM386). FMUP uses the processor's flat model mode to update
the flash part. If necessary, exit Windows and disable EMM386 before using
FMUP.
