Win98 reports correct amount of RAM.
I did notice that HDD had been set to CS but changed it to Master (didn't help).
I took the machine round to a mates last night who basicaly tried everything I've already tried (including your suggestions).
He runs Linux (Suse) on his M/Cs and tried installing that. It sailed in, no prob. I've been thinking about trying Linux for a while......maybe now's as good a time as any (cheaper than the alternative - new hardware).
I've just been reading up on Linux Ubuntu. Do you know much about this?.........Should I be re-posting this elsewhere?
