Ultra ATA card doesn't seem to provide Ultra speeds.

[Buckie]

Hello again. Sorry I just forgot to provide at least a version number.
Stupid me. It's FreeBSD 5.1 RELEASE and here's a dmesg output.
Also, it's not that it 'doesn't work', it works, but I see no
difference in speed after changing transfer modes (from WDMA2 to
UDMA6)

----

I ran a dd:
dd if=/dev/ad1 of=/dev/zero ibs=8192
...and cancelled it after some amount of time:
2321+0 records in
37136+0 records out
19013632 bytes transferred in 27.876118 secs (682076 bytes/sec)

I don't use static2 ata device numbering hence Maxtor is assigned ad1,
but it would be ad4 if things were static.

Experiemnting with ibs value I can get speeds of up to 16MB per
second. But no more.
