First LED is 1, and I counted from the end of the board that hasn't got a connector to the outside world (ie, not the end where the PCI-bus and the disk-connectors are, but the end with the little black plastic thing that support the board. The end I'm talking about is where usual PCI boards are no more (due to being smaller) :-) > If it is a transfer LED, then the DMA engine is stuck.

If you start wiping disks, a pre-alpha version of my testbox building scripts are at http://www.freebsd.org/~eivind/testbox-0.1.tar.gz Eivind.
