Reprogramming EPROM's

[Rossbx]

Just wondering if anyone here knows how to reprogram an EPROM or BIOS chip. I have an Old Soltek SL-85DR2 motherboard here that was working like a charm up until I flashed the BIOS and killed it . The BIOS update I installed was corrupt unfortunaqtely. I have a new eeprom and the correct BIOS update for the board now; I just need to have it reprogrammed.

I know there is equipment available to do the job but in reality it is a bit expensive for a once off job

Any assistance would be appreciated.

Thanks Guys and Gals

I am not sure of the size as you put it but the numbers on the chip I have here is as follows;

SST
49LF002A
33-4C-NH
0323052-A

The original one out of the board has the following on it;

SST
49LF002A
33-4C-NH
209195-A

in ballpark figures, the chip measures approximately 11mm x 14mm and is 32 pin

I hope that helps...

[Rossbx]

Yep, 4 sided chip...
If you want to have a crack at it, I will post it to you: just let me know

[delcowizzid]

im in nz but more than happy to have a crack LOL they are reprogrammable so you could send your bad one even if you wanted i should be able to reprogram it if it only has the wrong file on it ill pm my address

[delcowizzid]

can you not flash it in directly via floppy drive should be able too thats how i did mine ages ago

[Rossbx]

Yes that is how it is normally done, but since the corrupt BIOS was installed, it won't post. The CPU fan spins but that is about all that happens...
