NAME
     uk - SCSI user-level driver

SYNOPSIS
     uk* at scsibus?

DESCRIPTION
     The uk driver provides support for a process to address devices on the
     SCSI bus for which there is no configured driver.

     A SCSI adapter must also be separately configured into the system before
     this driver makes sense.

IOCTLS
     The uk driver has no ioctls of its own but rather acts as a medium for
     the generic scsi(4) ioctls.  These are described in <sys/scsiio.h>.

FILES
     /dev/uk[0-255]  uk{x} is the 'xth' unknown device found.

DIAGNOSTICS
     All scsi(4) debug ioctls work on uk devices.

SEE ALSO
     cd(4), ch(4), scsi(4), sd(4), st(4)

HISTORY
     The uk driver appeared in 386BSD 0.1
