I bought a IBM socket478 motherboard (second hand) and it has no model number on it. I want to get a wiring diagram for the front panel so that i can power it up to see if the monitor shows me a BIOS. There are 2 connectors on this MOBO one is marked F_PANEL2 the other is marked A_F_PNL. The only identity on is is IBM in large letters and REV:1.5 The layout is 3 x PCI 1 X AGP 2 X DDR RAM 1 x POV3 2 x IDE 1 x FDD The back panel has Keyboard Mouse 4 x USB 1 x Ehthernet Sound Onboard Video 1 x Serial port 1 x Parallel port
