That chip might not be the bios chip, it might be the password chip,
don't mess with it.

See if you can download a program from IBM for reflashing the BIOS.
However, I'm suspicious that the problem is as it seems. changing the
hard drive shouldn't cause this.

Try resetting the BIOS settings to factory default, sounds like
something got corrupted. You don't need to fiddle with hardware, the
firmware will rewrite the settings and generate a new checksum for
you.
