I've been interested in using an openbios for a while now and recently decided to seriously research it. I didn't know which one to choose but coreboot has a well documented and easy to understand wiki.

Question1: Coreboot seems to run on my architecture but it's slightly different from the GA-M57SLI-S4 it supports. By the below info, am i supported?

Question2: Compared to the other openbios projects, is coreboot the best?

Question3: Is installing an alternative bios safe?

I've actually been curious about this too...especially your 3rd question.

I wish I had an answer for any of your questions.

Question3: Is installing an alternative bios safe?
I'm mildly curious as well. Part of me wants to shy away from using any BIOS other than one provided by the manufacturer even though I've encountered anecdotal evidence that some BIOS manufacturers get up to tricks like tinkering with theirs so that Windows works with it better than Linux.

I'd like to know this as well, especially #3.

I want to flash the VMWare bios now... I want to see what catastrophies could occur.

I have an idea...and it might sound crazy...

If you have an old box you really don't care about, why not try and flash that bios with openbios. If it works, you should be able to determine what is better about openbios and what is not. Also, it should give you an idea of what it might do with your 'main' box. If it doesn't work, then you know th opposite.

If you do not have an old box to play with like this, maybe see if someone you know has one lying around not doing anything. I know people who buy new computers and put their old ones aside because they are not really technologically inclined and do not know what to do with the old technology.

You could order a spare Bios for your mobo, just in case...

Hmmm, good idea.

I ordered one from Biostar, just waiting for it to come in :\

Good call.

Also if you have two compatible motherboards, you can actually switch the BIOS after you have booted your system, and burn the original image back on the bad one. ( If all else fails and you don't have a spare. )
But I think you have to be a bit hardcore to do that.

I did it once, and it worked like a charm, but I was pretty nervous I'd short something in the process, ending up with two dead boards.

It's much better to be prepared...

Question3: Is installing an alternative bios safe?
I'm sure the answer to that question van be found on the websites of producers of alternative bioses, but I'm not in the mood to go look it up.

Anyway, educated guess : using a suitable alternative BIOS is probably save. Installing it is the tricky part, and you may end op with an unusable system.
Also, the warranty on your PC will probably no longer be valid when you replace the BIOS.
