I got that when I did what the pciide(4) manpage says NOT to do:
Quote:
For proper operation of UltraDMA 3 and higher modes a 40-pin,
80-conductor cable must be used. On some controllers, the pciide driver
can probe the chip and see if it detects that an 80-conductor or
40-conductor cable was used. If not, it will down-grade to UltraDMA 2
mode.
