NAME
uk - SCSI user-level driver
SYNOPSIS
uk* at scsibus? target ? lun ?
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.

The uk driver appeared in 386BSD 0.1
