Thanks a lot for your opinion guys! You've been great! Here's what I'll do. First, I'm going to try win98se, allthough I agree with what you've suggested, it'll be too slow or won't work at all. Then, if that crashes, I'll try win95 osr2, and finally BeOS or linux as a final way to get it up and running. I can't get my hands on NT 4.0. Now, fingers crossed, I'll install a minimalistic win98se with IE 5.0..
I'll let you know how it turned out, but I won't install until this weekend, I suspect.
