I suspect that you've got the RAM cache on in one case and not in the
other. If you really want to test this, it is probably a good idea to
remove peripherals (like hard disk), remove the battery for a few minutes,
then boot up. You have to be careful about claiming that the machines are
configured the same way. If you were to (say) have a 700K ram cache and
try and run a large program, you can find funny errors.
Good luck, David Gelphman daveg%slacvm.bitnet@forsythe.stanford.erc,
