Both drives are manufactured by Fujitsu. The Bios detects that the first drive uses UDMA 4 and the second drive uses UDMA 2. When I run hdparm tests on the drives with DMA turned on, my whole system freezes up but the tests run fine on the second drive. In addition, hdparm -i doesn't list UDMA-4 as one of the DMA modes for the first drive. Now that I have given you the scenario, I would like to ask you how can I disable the DMA check during FreeBSD installation as it seems to be causing a fatal trap exception during the DMA check?
