I have a DELL-branded "CERC" AMI MegaRAID IDE RAID board. FreeBSD
recognizes it as the normal AMI SCSI RAID card with driver "amr".
It's my only disk media. I built an array in BIOS then installed
FreeBSD on it.
When installing FreeBSD-5, I think I had to use the 3rd floppy image
which had the "amr" driver on it, as I don't believe it was built into
the kernel on the boot/root floppies. After install, I added "amr" to
my kernel def and rebuilt. I see now my GENERIC file has "amr" in
it. Perhaps I'm confused or maybe it didn't have it back then.
So if you've already got FreeBSD installed make sure it has the "amr"
device built in. If you're installing from scratch, check the 3rd
floppy for stealth drivers.
Not sure this helps for your specific hardware but it's worth a shot.
