Hi,
--System
FreeBSD 4.8 release
It is a kernel that I recompiled only to enable SMP.
The same error comes with the generic stock generic
Kernel.
It is a dual Athlon MP 1800+ on a tyan MB. The Raid
card is a TX-2000 with 2 Hot swap superswap enclosure.
The only other IDE device, the cd-rom is on the IDE
controller on the motherboard. The raid is a RAID1
with 2 Western Digital 80 Gb, 8 Mb cache, 7200rpm,
each of them is ont a separate channel. I checked the
cable and they are connected on the right side. I
even tried to put them the other way around and I get
the same error message.
--Problem: FreeBSD only puts my drive in udma33 while
the Motherboard, cables, enclosures and drives support
udma100. I don't know if it is a bogus error, because
I don't know how to test it (like hdparm in linux).
--Other data:

Nothing interesting in /var/log/messages
Other logs can be provided upon request. I just don't
want to make the post too long.
Thanks for your help.
