Hmmm, okay, so you can't run too much with an HD that small, if you upgrade the HD you can run XP if your processor speed is more than 233mhz.
You can barely run Windows 2000, which has the minimum specs of 133mhz, 32mb
ram, and 700mb HD.
Also, when I said "Memory" I meant what is the amount of
RAM you have installed, to get that you go to the Control Panel and click on "system". It should say it there
