I've exactly the same issue: on a PIII866, only one IDE CD, Floppy and a
RAID1 array on the FT100TX2, no way to boot on the CD...

It works with there are no array on the card.
(No array defined, Ctrl-F for bios or <I dont remember, ESC ?> to continue).
-> I just installed on 'ad4'(prim. master from raid card) disk, edited
fstab to mount ar0 instead of ad4, then build (on the card's bios) a
raid1 with ad6(long time copying...), then it boots from the raid. Still
not from a FreeBSD5.4 RELEASE CD, nor a FreeSBIE 1.1 (based on 5.3).

I can do some tests if needed, even if I'm don't really understand more
than 'hello world', I know how to apply patches ;)
