    might need a beefy power supply, i heard it pulls at least 300 Watts itself. Don't know if i need very specific motherboard platform / cpu or not at this point, but even if that is met it still might need a custom BIOS and even possibly additional hardware hooked up to the card itself via one of the board interconnectors. Still also no software

    no video output

    1 long, and 3 short beeps, sorry --- even with using Above 4G Decoding option, but my motherboard does POST with only the Larrabee in as a VGA adapter

    the actual Larrabee card itself has a PC Speaker

    i put in a second video card, and the beeps no longer are present on the Larrabee



    but the Larrabee isn't appearing in the device manager, and it's not appearing in the BIOS as linked in



    the larrabee seems to be alive though... maybe just needs an old motherboard



    if i remove the 2nd video card the larrabee gives 1 long and 3 short beeps again

    think I was confusing the Phi/Linux stuff from the "prototype" thread.

    Huh, a couple of differences off hand.

    Video out ports seems to have been rearranged. DP, DVI and HDMI on your and then DVI, DP and HDMI on Slaventus' board. The Silicon Image (?) chips move accordingly. I have a feeling if you were to look up the Silicon Image part numbers on those chips you'd find that they were just DP -> HDMI active converter chips.

    There are a couple of SMD chips near the connector on the upper left. Actually... what it is that connector? Some JTAG or other debugging port or perhaps connector for a genlock board?

    There is a spot for a simple two pin connector near the six pin power connector on your board. I can't tell if that is also in Slavantus's board or not due to the blur in the corner. Also both boards have a jump near the 6 pin connector. Any labels near it to identify what it does?

    There's also a blue bodge wire on mine near the DVI connetor (also a PIN Header there too not present on his) His is missing the PC Speaker too. There's an entire chip missing from Slaventus' board compared to mine near the FAN header to the bottom right

    those chips are both the same "Parade" DP530 ES (unreleased engineering sample DisplayPort controllers)

    Was that card made around the 8800 gt era? Curious what it would compare to if you got it up and running. Good luck!

    A diagnostic piezo buzzer isn't an uncommon feature among video cards, I have many with them.

    I have an AGP 7800GS OC from BFG, it was a really good card when AGP was on its way out.
