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.


Remove the motherboard battery for a few minutes and then re-install it. That should but if it does not, then the BIOS ROM chip on the motherboard is probably faulty. It could also be another component on the motherboard.

Recommendation: Troubleshoot the motherboard.
