I havew a IBM A-31 that died on me. Boots up locks up in different modes but always locks up. I have two 256 meg ram and I swapped out the ram memory with each other socket and elimated each. Same result. I resorted to using my old thinkpad 600e which seems to be a rock solid machine. Only problem is it's only a 5 gig HD, My A-31 is a 20 gig, they are not interchanging and I can't figure out why. Niether drive seewms to be compatable with the other machine. Does this seem right?
