I tried the windows xp update but apparently i have a pirated version of xp so they would'nt let me download it. Let's see.. it's a Intel Pentium 111 600MHz 100 FSB Coppermine Proccessor with 597 MHz 224 MB RAM, the micron site said that it's upgradable to 700 something MB so i'm going to do that also a Seattle 2P11 440BX ATX Integrated Comp motherboard, Western Digital XL 20.5 GB IDE ATA66 7200 RPM if there is anthing else thats relevant that i left out let me know because i'm just copying this stuff down i don't know what any of it does. Ok so i plug my rio cali mp3 into the USB and it does'nt even show, when i do a device check it just say's unknown device. Thankyouforyourtime
