Bad Bios Flash

I have flashed my bios and now the power goes on for a second then off.
Motherboard is ASUS P2B Rev 1.10. I think it is fried until it can be reprogrammed.
I flashed if with P2B-F Bios bx2f113a and ignored the warning that the model type was different. Books and all documentation said P2B-F except the stamp on the board itself.

I backed up the BIOS at flash time.

I also have a P3B-F board with a 440-BX chipset same as the P2B is it possible to boot the P3B-F system up with its original BIOS into dos. Then remove the good P3B-F BIOS chip while the machine is up and replace it with the bad P2B bios chip and then flash the bad bios with the backed up bios. Then do the a switch.

Is this possible or am I dreaming in technicolor.

Nope, not Technicolor... but FAQ. Look up "hotswapping".

When the markings onto the board say P2B then it 's a P2B and no P2B-F .
If someone sold you the board as P2B-F then he sold you the wrong board .

With Hot-Swap please pay kindly attention on the correct orientation when inserting the flashrom into the socket > small noth in socket and flashrom have to look into the same direction .
Otherwise the Flashrom is killed .

What is the best way to remove the CHIP and can you mix MB's but same manufacturer ASUS and same Chipset (440-BX)

Does the power going on for a second then off demonstrate a bad bios?

Not necessarily, it could just mean that the BIOS did not find what it expected. If the BIOS is correctly flashed, but the wrong version, it will not complain that the BIOS is corrupt. It will assume that it is in the right board and then fail to initialise it correctly.

I use metal slot cover to remove the chips - of course with the power unplugged (even the ATX standby power can burn components if you short something accidentally).
