  1. Look in the manual or on their website what the light means.
  2. Hum... The Pavilion 700 PSU has a really strange feature! There is a small plug for a fan (3 pin) that is plugged into this motherboard from the PSU.

    The Power Supply (PSU) died so I replaced it with a PSU that does not have this funky little MO plug- Now I can't get to the BIOs and the system doesn't see any of the IDE drives I've put in it!

    Can't find a keyword search to look into this issue either! Is that plug needed to power the Bios? I am very shy of plugging anything other than the Mulx and the ATX 20/24 pins into a MO!
