Another question about Ultra-Wide Adaptec support:

Can someone explain why it is running at 10.0Mhz instead of 20Mhz? I
have that problem too, whereas the PC of a colleague of mine is
running at 20.0Mhz (40 Mbytes/s). We checked the setup without luck
and have not been able to locate any differences other than the firmware
versions of the Adaptec and the disk.
