XP will do that if we didn't install the motherboard SATA drivers.
i have a new MOBO processor, video card and the whole shooting match....i am reusing the hold HD(80gig SATA) and want to add a new HD(250gig SATA)...i can get my PC to work with the old HD only, but when i plug in the new HD, the PC wont recognize it...here are the specs on my MOBO and processor
Biostar Combo w/ Intel Celeron D 336 (2.8GHz) (LGA775)
Biostar P4M80-M7A Socket775 P4M800 FSB800 DDR A&V&L M-ATX Motherboard
a little background....when everything new was installed, everything worked fine, then we unhooked the floppy drive and the new HD was fromatting....it worked fine, then brought it home and the PC would not start up, as if it was looking for the OS on the new(empty) HD...when i unplugged the SATA cable it works, but just with the old 80 GIG HD....anyone have any suggestions, other thant he one the wife had which was "you should just buy a Dell".....not cool, i know
