I've got a 386SX-20 with the old school AMI BIOS. After replacing the dead external battery, it is giving an invalid XCMOS checksum error. Normally that's no problem - go into extended setup, write registers and exit...
However this BIOS has no extended setup option. The only menu options are exit for boot, run CMOS setup, and run diagnostics.
Any ideas on how I can fix this? I've cleared the CMOS but that didn't help. It seems some BIOSes didn't have the extended setup program, but then why give an XCMOS checksum error? 😕
Thanks,
Stu
