"Unfortunately, this particular board is not currently booting from the system in which it was tested in (the only one I have with an AGP port). I have not been able to try it in other systems. However, I do know that this board has booted previously, but it has sat in a closet for several years since then and I do not remember the circumstances in which it previously booted.
The 4 fans DO run when power is applied. Again, please note that currently this board does not display a BIOS screen during the boot process, and does not appear to boot on the system it was attempted, so please bid accordingly."
Ist wahrscheinlich defekt 
Edit:
Sorry, ist nicht neu. Wurde weiter oben schon genannt...
