The very first screen reads: BIOS ROM CHECKSUM ERROR. And it prompts to insert a system disk in floppy A. Would someone help me?

FIC KT133a board (AZ11EA)
Duron (not Morgan) 950 MHz
TNT2 Ultra GPA
IBM 45GB hard disk
128 + 256 MB generic memory (7.5 ns) set to default (SPD?), no interleave,

The system used to work. A few days ago I turned the computer off, and now I get that CHECKSUM ERROR screen. When it was running,
FSB=133
CPU multiplier 7X (for basically 950 MHz)

I replaced the IBM hard disk with a Seagate (removed from a working computer). No change.

Thanks.

see if it helps any

the floppy may be askin to flash it
i read another post on this same thing but i cant find it right now... ill keep lookin

oh and here
 
ehhh, that error blows

I dealt with it once, matter of messing with a bunch of different settings I can't remember until it was happy.
 
Thank you [almr] for the links. They were VERY informative. Can I ask you a few more questions?
1) I checked the beeping code. Memory problem. The 256MB (Centon PC133 memory) was the cuplrit. Now I am using the 128 MB unit only. Can memory go bad abruptly?
2) Still when I boot, it does not give the "everything okay" beep (one short). It just goes to the boot routine and says "CHECK SUM ERROR. Loading default." The screen stops and prompts to choose either F1 (continue) or DEL (setup). Hit DEL but nothing happens. I have to hit F1.

I have a few more problems to solve but at least the computer is working. I plan to continue to visit the links and re-read them as it progresses.

Thanks again.
 
i cant really tell you how the technicalities of how memory goes bad, just that i know it can.
also, on my old board, the indicators said it was a memory problem, when in fact the board had blown a couple of capacitors. i guess the lesson is, the lights can help, or can be completely wrong. you may want to double check that dimm in another computer or in a tester to make sure that it is in deed kaputski.

i would suggest backing up anything important now while you can get in. i think in one of those threads it explains why he cant get in to change stuff, but it can boot.

i had to post the links b/c i am not well versed in the inner operations of how the bios works line by line.
