If you don't know it's a Dual AMD 1.53Ghz with 1GB of RAM (probably be 3GB, the max, in a month or so) running Windows 2000 Server. I understand compiling the kppkpp TB is probably out of the question, even with my "good" hardware. I doubt it'd even fit it on my HD uncompressed anyway. I was just curious if I could. Slate
