The nice thing about SCSI is that the controller negotiates the best protocol
with each device. This means that you can mix narrow and wide, SCSI-2 and Ultra
SCSI on the same controller. The only restriction is that the total cable length
 is limited to to most restrictive type (Ultra SCSI right now).

I have an IWILL Motherboard with onboard Adaptec 2940U (not wide) controller. I
have an IBM Ultra SCSI disk, an IBM wide SCSI-2 disk, Archive SCSI-1 tape drive,
and Plextor SCSI-2 CDROM. Everything works perfectly.
