Still haven't had a successful boot yet. My current setup has 8M ram and I've turned off everything that looks like cache, etc... I'm really looking forward to ripping all the jumpers off the motherboard and putting them back in all sorts of interesting configurations. That should make my weekend (or maybe I just get a life). My question is ... Is there any versions of boot.flp that are more system tolerant? Does anyone have a customise boot that is less system sensitive? Should I try the latest snapshots? Would it drive me crazy? Maybe my P.C would work better as a doorstop than a unix box. John John
