Grrr, its always something! I have a dell demension 5100 with NO ps2 ports, so I used a ps2>usb adapter with my ps2 keyboard and a usb mouse to do a clean install of xp. Both are fully functional before setup, then 1/2 way through when I have to put in a name- nothing, no go. I read where somebody said change the legacy usb support in the bios, but I have support prior to setup, so I don't see how that would help. ideas????
