can I upgrade my windows 98 to this?

yeah you can the your barely above the lowest requirement

Minimum requirements:

400 Mhz, 128 Mb RAM, 3 Gb on HDD

A Pentium II is about the least processor you can use for Linux with a graphical interface. The hard drive is fine - I've installed Linux on 1GB partitions, so you have plenty of room for a swap partition. The RAM size is the problem - I'd upgrade to at least 512MB - preferably 1GB. (The swap partition should be twice the size you expect to expand your RAM to - so make it 2B, even if you're going to start with 196MB.)

Damn Small Linux would probably be one of the better choices for you, because of the size, but look around at http://www.distrowatch.com/ - there are a few hundred Linux distributions now.

You don't need to buy a copy of Linux. Try one of the many free LiveCDs from the likes of Ubuntu/Kubuntu, Mandriva, Fedora, etc.

A LiveCD will run from the CD without installing anything on your PC. Try before you, er, install. For the most Windows-like appearance, choose the KDE GUI (e.g. Mandriva, Kubuntu). Although KDE may run a little slow on your system. You could take a look at the lightweight XFCE GUI instead. Most distributions come with that too.

Not sure but in my experience Linux needs a lot of room. You may need a larger hard drive. The rest should be alright.

That's the HD I have w/ XP in a Pentium III. I'm looking for a much bigger HD cause this one isn't nearly big enough.

I think you can do it, but you'll hate it. Stay with '98 or do a serious hardware upgrade. Hope you appreciate the honesty! Good luck...

No you can't
