Hurray, using a normal cable works. I got 2 cables for $0
from a friend in a computershop ;-) A freebsd user, which
I gave a promotion CD last year ;-)

dmesg | grep ata:

atapci0: <Intel PIIX3 ATA controller> at device 7.1 on pci0
atapci0: Busmastering DMA not enabled
atapci1: <HighPoint HPT366 ATA66 controller> port 0xac00-0xacff,0xa800-0xa803,0xa400-0xa407 irq 15 at device 14.0 on pci0
ata2: at 0xa400 on atapci1
atapci2: <HighPoint HPT366 ATA66 controller> port 0xb800-0xb8ff,0xb400-0xb403,0xb000-0xb007 irq 15 at device 14.1 on pci0
ad4: 39082MB <Maxtor 54098U8> [79406/16/63] at ata2-master using UDMA33

Do you think there is a chance to get UDMA66 running, although
for one disk UDMA/33 should be satisfactory ?

BTW, what mode is MA DMA or something like this ? The abit supports
two modes I never heard of before. PIO is known UDMA is known, but
something like M DMA or MA DMA ???

Then an idea. What about something like atacontrol, to overwrite
the speed settings, if you have to like in this case ? Would it
be much work for you or worth the effort ?

Would be fine to use the better cable with low speed...
