I was running this with a Fireport 40 UW SCSI card, a WD8013WC ISA Ethernet card, and a Diamond Stealth 2000 3D PCI video card. The P6DBE (http://www.supermicro.com/PRODUCT/MotherBoards/440BX/p6dbe.htm) does not reliably run two processors. One works fine, but with two the system will boot and run for a short time but crash or hang within a few minutes. I contacted Supermicro, but they were not willing to look at the problem unless I could reproduce it using NT (not having a NT copy around, I haven't done that). I was using the Rev 1.x motherboard, and this has since been obsoleted with a Rev 2.x motherboard, so I suspect that the Rev 1.x board has some inherent hardware problems. The Rev 2.x card may well work fine - I haven't tried one. To confirm that it wasn't FreeBSD, I swapped in an Intel N440BX card, and this has worked flawlessly for a couple of weeks with the same kernel that I tried with the P6DBE card.
