Zalezi ciste jen na driveru prislusneho SCSI radice. V kernelu 2.2.14
to rozhodne funguje napr. s Adaptecem 2930:

(scsi0) <Adaptec AHA-293X Ultra2 SCSI host adapter> found at PCI 13/0
(scsi0) Wide Channel, SCSI ID=7, 32/255 SCBs

a v /proc/scsi/aic7xxx/0:

Dale je treba mit patricny hardware: SCSI radic, kabel, terminator (!!),
disk. Pokud jedina komponenta 80 MB/s neumi, pobezi to pomaleji.
