Don't even need to do that, just having another machine that uses the same
size eeprom socket will work.
Shut down your working pc, carefully loosen the BIOS chip enough that it
will come out easily when you need it to.(this is FAR less risky than
trying to use a chip puller on a machine that is active)
Boot up your machine into DOS/FreeDOS/whatever(just not windows).
Very carefully remove the bios chip(yes, with the machine on!) Label this
or something so you don't accidentally flash this one!(been there, done
that)
Put in the bad chip from the other pc.
Start your flash program, and flash the bad chip with the code update you
want.
Shut down the computer, take that chip out, put it back in the "bad"
machine, and make sure it works now.
Put your original bios chip back in the good machine.
I've had to do this dozens of times while testing hacked bios's for a
bunch of BioStar motherboards that wouldn't accept hard drives >32gig, and
for machines where the bios upgrade just plain didn't work.
I've seen a few laptops that used chips that were removeable, so the same
procedure would work for those.
