I recently purchased a replacement bios for a board I was having a problem with.
I was first going to use the bios hot-swap method but I did not have access to the same exact board to copy the bios from.
It made me wonder, If I get a bios flash program that does not do any checking (to make sure you have the right bios for the board), should I in theory be able to use a boot disk on a working board of any type (as long as the bios chip is the same type), swap the working bios with the one I want to program, then use the "universal" bios flash to program it with whatever I want, then simply replace the bios, and end up with the new bios for whatever code I want?
So here are my questions:
1) Is this method possible? Or do companies that offer bios chips (with any code you want) use a specialty piece of hardware to program them.
2) Does anyone know where I can find a bios flash utility (for the various types) that does not do any checking ? (I have not been able to find one)
3) Lastly, Is there a difference between types of chips? Meaning are all 32 pin PLCC chips the same? So I could just find a 32 pin PLCC chip from pretty much any board make/model and use it wherever I want? Or are there many many types and would not be feasible anyway unless I had access to a wide range of chips?
