BIOS ROM checksum error

By laro941 ·

I have a TYAN s1854 Tinity 400 MB and I am having problems booting up and also with my machine freezing up or rebooting in it's own. The most recent error during boot up was the "BIOS ROM checksum error" "detecting floppy drive a media INSERT SYSTEM DISK AND PRESS ENTER" and I did not have anything in drive A. I have also booted up and the hard drive was not detected. Any suggestions?

The read-only memory (ROM) containing the BIOS program is protected by a checksum value as a double-check that the ROM code is correct. This checksum is compared against the values in the ROM each time the PC is booted and if there is a mismatch, this code is generated.

Note: This error is not the same as a CMOS Checksum Error, which refers to corrupted values of the CMOS settings, the ones you set through the BIOS setup program. This error means the contents of the BIOS code itself are damaged.

Diagnosis: The BIOS ROM chip on the motherboard is probably faulty. It could also be another component on the motherboard.

Recommendation: Troubleshoot the motherboard.
