ok, heres the prob, I have a VIA EPIA mobo (the sort with built in EVERYTHING except RAM). The BIOS chip is a SST MPF 39SF020. A BIOS upgrade failure killed the mobo. I tried many many many times to hot-swap the chip into 1 of my other 3 machines but it doesnt work! GAH!
ok this is what ive done so far.
I have my main PC with another SST BIOS chip in it (SST 49LF020), I have 2 spare BIOS chips aswell as the failed VIA chip (Winbond W49F002UP12B and SST 39SF020A). I tried booting the main PC (its an ASUS mobo) and running its aflash.exe flasher. I couldnt get it to flash any chip other than the one already in there. I also tried AWARD, AMI and Uniflash but to no avail (I used the -force and -expert parameters for uniflash so it gets the right chip).
Something weird happened and my main PCs BIOS died on me too. No idea how but now it wont boot.
My 2nd attempt was with another machine (Compaq Presario 6000 series PC with a MS-6553 mobo, it also had an SST BIOS, dunno model number).
I used all flashers but uniflash wouldnt work on any of the chips EXCEPT the one from my main pc (the ASUS mobo)! I flashed the ASUS BIOS onto it and even though it said it was flashed successfully, it didnt work in the mobo. I then flashed the VIA BIOS onto it and it didnt work in the VIA either! I had no idea why.... then I came accross this site and I did some reading, now I know that there is no 1 standard for BIOS chips and some use different voltage and reading/writing ways.
Now I have 2 dead mobos and 4 BIOS chips.
SST MPF 39SF020 from the VIA board
SST 49LF020 from the ASUS board
Winbond W49F002UP12B which is a spare
SST 39SF020A which is a spare
Do I need to buy a new chip? my local electronics store sells SST 49LF020 for $15/each ($AU).
Thanks in advance and sorry for the long post. I hope I didnt leave
Some more info on the mobos.
VIA mobo is an VIA EPIA M10000 aka EPIA M. ( http://www.viaembedded.com/product/epia ... boardId=81 )
ASUS mobo is an ASUS A7V266-E ( http://support.asus.com/download/downlo ... uage=en-us )
Compaq Presario is a 6000 series PC (not sure which model) but the mobo is an MS-6553.
