I did have one problem wuth the board, which was that if I had ACPI enabled then the operating system would not boot, it froze at the point where it waited for the SCSI devices to settle. I got round this by disabling ACPI in loader.conf and it works fine. A couple of days ago I installed a second Opteron 242 in the other socket to build an SMP machine. The second processor is recognised by the BIOS - and I have also moved half the memory to be attached to the second processor. The BIOS still shows 1GB so I am pretty confident the 2nd processor works. Swapping the processors also works, so I know the chips are good. But FreeBSD will not boot SMP with the second processor installed. It behaves exactly as it did with a single processor and ACPI enabled - i.e. it stops at the 'Waiting for SCSI devices to settle" point and does not get beyond this. I have two SCSI controllers installed - a Compaq 5304 RAID controller and an Adaptec 29160. The system boots from the Adaptec. I do have ATAPICAM compiled in to the kernel, but I get the same result with generic SMP. I have upgraded the machine to 6.1-PRERELEASE and I still get the same problem. Does anybody have any ideas about setting about debugging this ? The motherboard has been flashed to the latest BIOS and I am running i386 not amd64 on the board. help! -pcf.
