Connect the cable to the other 68-pin plug.

On some dual-channel cards, only one channel goes up to 320 MB/s.  The other 
channel will max out at 40 MB/s, and is for slow devices (CD-ROM, tape 
drives, etc…)

You may find it necessary to limit the card to 160 MB/s.  Right now, if I 
try to run mine at 320 MB/s, the kernel blows chunks and fails to boot.

Whether you can, or cannot run the card at 320 MB/s, with the disks 
connected to the other plug, put your exact hardware info into bug 115351.
