It depends on which chip has gone bad. If it's the battery backed up one,
(the fat thick one), then you should just need a new battery. If it's
the PROM, you just have to have a prom burner and copy a good one to
the bad one. We've done this to upgrade all our pre 1.2 bootproms that
did not support security mode. Now all our 1's and 1+'s that didn't
have a security mode feature do!  The hostid, MAC address, and other
save information is stored in the battery backed up one. The boot information,
forth interface, and low level command configuration is stored in the
normal PROM, (which you should be able to buy from electronics firms
like Jameco)

 I just wanted to clarify this. We've saved a bundle just by copying
a newer PROM over older ones after blanking them with UV light.
