I have an AST with a socket 3 133mhz processor, and a friend gave me a Acer socket 5 166mhz motherboard to replace my existing m/b. Now, I can get the Bios screen which say's V 2.0. When I hook up my 3.5 drive, the motherboard say's "A drive not recognized" . I'am at a bit of a loss, when I go into settings in the setup menu the m/b recognizes my hd, but nothing happens when everything is hooked up? I would appreciate even the smallest insight into things I could try! You the MAN ( or WOMAN) if you can figure this one!
