It's possible that the problem is with the memory. However, since you've tested with each memory stick alone, then the problem would have to affect both sticks. Which would suggest that either you were unlucky and got a bad batch, or that the memory you've installed isn't quite right for that Mobo. Try memtest86 from http://www.memtest86.com/ --- it will very quickly pick up the sort of drastic problems you seem to be having. On the other hand, the problem may not be memory at all: the boot output doesn't say if the root mount works or not, so it could be the next thing that's tripping you up. Now, on my system the "next thing" that happens is a scan of the SCSI bus, but this box doesn't have any ATA or ATAPI devices installed. Can you verify that the system works with some other operating system? That should help rule out problems at the hardware level. > PS: I forgot to mention that I have also tried the trick mentioned > earlier in answer to a similar question: > --- > ok set hw.pcic.intr_path="1" > ok set hw.pcic.irq="0" > --- Uh? Your motherboard is a micro-ATX form factor, ie. not designed for use in a mobile system. I doubt that PCMCIA components are going to be on the critical path for installation. I'd be more suspicious of the ATA chipset. Is it recognised by that version of FreeBSD? How about trying out a direct install of 4.6, or at least the beginning of one --- use the floppy images from a FreeBSD mirror site, which should show PDQ if you can get past your current stumbling block. Take note of the information about hw.ata.ata_dma="1" and hw.ata.atapi_dma="1" in http://www.freebsd.org/releases/4.6R/errata.html.
