hello,
Can anybody enlighten me on how the checksum in the PC BIOS
are calculated ? I suspect that the last byte are adjusted so
that the total checksum are nul, but I don't have an EPROM
burner handy, so I haven't bothered to experience.
I have several times patched BIOS'es to cope with unlisted
driveparameters, but so far I have solved the problem by adjusting
other entries in the drive table to avoid changing the checksum.
Also, does it exist any tools for simplifying this process?
I have tried two; CMOSER and HTMU, but none of them worked the
way I wanted them to :-(
Prefer Email,
Thanx, Jan
