Is it possible to go back to a previous bios?

[Yodums]

I just updated my bios and the thing won't boot bugger, think I wrecked the bios chip/motherboard by updating to the lastest bios.

I tried resetting the bios by taking trying to take the battery out :/

If you have an ISA video card you can try making a boot disk that runs the flash utility on restart. Some boards will allow you to boot up with an ISA video card. About all I know to do.

If that doesn't work, I'd say you're shopping for a new BIOS.

Possible to use another bios from another board?

Has to be identical to the one that was in it. POST, start your flash process, then swap before writing. Otherwise, you'll have two bad BIOSes.

This method is, of course, done at your own risk. :cool:

I have heard of people using a cmos chip from another board- but it has to be the same board or one that is entirely compatible I believe.

I'd look for another unless you get a 100% certain reply from someone you trust! You could wipe out another chip, or wreck the mobo!

The board would beep or nothing it just boots up fan start spinning and no boot, and no its not the video card :D

Hmmmm I think I'll just bring back the motherboard to the person I got it from, since I didn't modify anything Chaintech even recommends you to update the bios regularly :D

Board is under 1 year waranty as well.

Sounds like you have killed the motherboard there. Where did you get the bios from? Was it from a site that has lots of other bios updates?? I hope you can fix it. Dead mobos are so frustrating!! :mad:

[Yodums]

Sad to say but from the chaintech support site.

PS:

I really think it wasn't a bad motherboard but I'll just say it is anyways since it is a full of load crap motherboard where the seller ripped me off saying it was an Abit.

And the status of the flash was OK where the status of all boxed were white. And the white legend boxes meant "Write OK"

You can do a "hot swap" with the BIOS chip, but you have to be careful. I know it works with similar chipsets, I've done it with one board that has a kt133 chipset, to load a BIOS for a board with a KT133A chipset. You can run into a BIOS utility problem. Award Flash will detect that the BIOS isn't for the board you're flashing, and stop. This is good to keep you from loading the wrong BIOS. This would happen if you pulled the BIOS chip out of another computer, and stuck the dead chip in. If you go to Wim's BIOS, they have a free utility called Uniflash, that will detect the incompatibility, warn you, then alow you to proceed if you want to. Load the BIOS, remove the chip, put the original back in, and you're in business. Just don't insert the chip backwards! It will immediately get hot, and fry. There is a small mark on both the chip, and the socket. Line them up, and you're ok. Wim's BIOS also has all of the details on performing "hot swaps".

Thanks but the experiment maybe out of my league and I just gave it back to the vendor and said check it out. I don't want to return it with big holes where the bios chip is or I'd obviously void my waranty. Well he said it should be done very soon, maybe this time he'll be giving me a reasonable board.

If you can get another board out of the deal, the it'd be crazy to take a chance. But I thought you might want to know about it anyway, just in case. Good luck with your new one!
