    Just built a new AS8 system and when you power it on the fans spin a red LED
    lights up on the motherboard to join the green LED and 00 post display
    already lit before powerup, the AC2300 POST starts at 8.3 (ATX Power Supply
    Ready) then changes to 9.6 (De-Assert CPU core voltage) then the machine
    shuts off with a 9F on the Post display which isn't listed in the manual.
    Here's the specs... P4-2.8Ghz 800 Mhz FSB chip, 1 GB of GEIL DDR PC3200 Ram,
    ATI Radeon X700 Pro 256MB, and 350W ATX Power. I've built many systems in
    the past and my first thought was the power supply so I hooked up my
    Thermaltake 560W powersupply from my other computer and still no dice.
    Changed out ram with a paired set of OCZ DDR, and also tried a ATI Radeon
    9800 256, and still the same problem. Do I have a bad motherboard? CPU? or
    need a SPECIAL power supply? I'm stumped. I have noticed that some other
    people have the same problem throuout the net, but no good solutions yet.

    Well, I finally reached a very helpful human being on the phone at Abit tech
    support and he walked me through some tests. It seems that when you get
    these post codes something is not right with the power. If you have replaced
    the power supply and made sure there are no shorts by testing the board by
    removing it from the case and hooking it up out in the open on a table,
    Hopefully not a metal table ;), remove all ram, cards, and cables. You
    should just have power hooked up, cpu and fan, then power up the board. If
    you get the same sequence of events, ie., 8.3 on the post followed by 9.6
    then a shut off with a 9F then the final thing is to get an RMA an return it
    because the board is defective.
