VPO(4)                 FreeBSD Kernel Interfaces Manual                 VPO(4)

NAME
     vpo -- parallel to SCSI interface driver

SYNOPSIS
     device vpo

     For one or more SCSI busses:
     device scbus0 at vpo0

DESCRIPTION
     The primary purpose of the vpo driver is to provide access to the Adaptec
     AIC-7110 SCSI controller built in the Iomega ZIP drive.  But it should
     also work with the Iomega Jaz Traveller parallel to SCSI interface.

     The driver has been extended to the ZIP+ drive which is based on the
     Iomega Matchmaker Parallel to SCSI interface.

USAGE
     The driver should let you use a printer connected to the drive while
     transfering data.

     DOS and FreeBSD filesystems are supported.  When mounting a DOS filesys-
     tem or formating a FreeBSD filesystem, check the slice of the disk with
     the fdisk(8) utility.

     In order to unixify a ZIP disk, put the following in /etc/disktab:

     zip|zip 100:\
             :ty=removable:se#512:nc#96:nt#64:ns#32:\
             :pa#196608:oa#0:ba#4096:fa#512:\
             :pb#196608:ob#0:bb#4096:fb#512:\
             :pc#196608:oc#0:bc#4096:fc#512:

     and use disklabel(8).

     If you have trouble with your driver, your parallel chipset may not run
     properly at the detected mode (NIBBLE, PS2 or EPP). Tune the ppc(4) boot-
     flags to force other modes.

SEE ALSO
     da(4), lpt(4), ppbus(4), ppc(4), scsi(4)

BUGS
     During boot, the driver first tries to detect a classic ZIP, then a ZIP+.
     The ZIP+ detection is intrusive and may send errorneous charaters to your
     printer if the drive is not connected to your parallel port.

     The vpo manual page first appeared in FreeBSD 3.0.
