Old Laptop w/2 seperate Win2ks- help?

*I’m far from the real tech-savvy people on this site but i have a probelm and not sure what to do.

Ok, so I got an old laptop(133mhz and 40 mbRAM Ascentia J) for school- solely for Office suite, AIM and internet on a wireless network(foxfire or explorer, whatever).

Problem: Somehow when trying to put in win2k as a fresh install thinking this would solve problems, I made 2 OS’s on this guy! It ran slow on win2k(i wonder why..lol) and i think need to scrap them both and get a less stressing OS for this laptop.

I have no CD-Rom, so I’d need to send myself the new OS via LAN(I think either Win NT or 98, leaning towardsNT for less requirements) and install- what would I need to do to actually do that and fix this mess?

Thanks in advance
