How safe is hot swapping a BIOS chip? - Page 2

post #11 of 14
It is possible from what I read before, I don't know how safe though. I also don't know if it would work with another BIOS chip, you can hotswap the same chips. When I had to replace one of mine from a bad BIOS flash, I did a bit of research on this but that was a long while ago. Some time after the initial bootup the chip can be removed and replaced with the faulty one, then you can flash the bad one. You just need a good one to start up.

You would just have to research it further as I can't remember all the steps, but I just remember that it was possible. I was actually going to do it, hotswap the chips and then have a backup but after I got my computer working again I just left well enough alone lol.

I've done it, and gone on to boot windows without a bios chip even installed. Just make sure the pinouts are the same.

Pretty sure that they are the same. What program did you use to flash it?

The chips are the same I think.

I had fun doing this last weekend. What a mess. Determined the problem to be the source mobo - for some reason it can erase the BIOS, but cannot rewrite at all... hooray for blank BIOS chip!

I was lucky though. Had a twin board of the same vintage handy that COULD flash a new BIOS without screwing up.

I'd buy another chip if I could do it again, if only to do the hot swap after getting it up so there's a good spare.

Some sites make lists of "compatibility" for BIOS hotflashes, might search for that. DEFINITELY need to have identical chips.
