Checksum error on an old computer

[mystikl]

My friend's computer stopped working today. When I turn it on beeps once then it starts beeping like crazy and it gives the message "Checksum error loading default checksum" and at the bottom "Press F1 to continue or Del to enter setup". Thing is when I press F1 or Del nothing happens. It's pretty old and I doesn't have Clear Cmos pins so I don't have any ideas.
Thanks in advance.

You need to be more specific if you want us to be able to help you without making useless generalisations.

Make and model would be a good start.

It's possible that the CMOS battery has gone flat, which could lead to this. However, I've seen this type of problem where the battery was good and the motherboard was bad.

It's a Matsonic board with an i845 chipset I believe.


ed: before that checksum error happened it was displaying some mumbo jumbo like 4 lines of 0FD10 FD001 in the upper part of the screen.

Still too vague. Please try to find the exact make and model as I requested, then myself and other people can help your research the problem, or if you're lucky, they'll know straight off.

Beeps like crazy? The pattern is important, too, see flw website and please tell us what beep pattern you hear.

Sorry I didn't pay attention to the pattern, and I am at home now so I can't check it. But the battery giving out seems plausible as the computer had this problem since 3 weeks ago but it was shutdown for that period and today it booted in Windows but nothing moved. When I rebooted it gave that mumbo jumbo an the third time it gave the checksum error after I unplugged the floppy cable. Weirdest thing I've ever seen.

ceksum

change bat CMOS 100% ok

I changed the battery and cleared CMOS, same problem. And the beeps are 3 short I think and then just short beeps quarter of a second apart without interruptions . I discovered that the beeping stops if I unplug the mouse and keyboard.

You might get more and better replies if you actually did what I said to do on post 2, instead of just ignoring it...

The board is a Matsonic MS9007c.
