remember that windows 95 runs on fat 16 which can only recognize 2 gigs of hard drive space.
what you could do is get a program like partition magic by powerquest, install it on a new xp system, partition out 2 gigs, make sure to install boot magic, boot into the new blank partition, install 95. THis way you can use xp and 95 at the same time. It should run pretty well. If you can get the 2nd release of windows 95, i think it will support fat 32, which can have like 10 or 20 gig drives.
