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 scbus

DESCRIPTION
     The vpo driver provide access to parallel port Iomega Zip and Jaz drives.

HARDWARE
     The vpo driver supports the following parallel to SCSI interfaces:

     +o	 Adaptec AIC-7110 Parallel to SCSI interface (built-in to Iomega ZIP
	 drives)
     +o	 Iomega	Jaz Traveller interface
     +o	 Iomega	MatchMaker SCSI	interface (built-in to Iomega ZIP+ drives)

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

     DOS and FreeBSD file systems are supported.  When mounting	a DOS file
     system or formatting a FreeBSD file system, 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 bsdlabel(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)
     bootflags to force	other modes.

HISTORY
     The vpo manual page first appeared	in FreeBSD 3.0.

AUTHORS
     This manual page was written by Nicolas Souchu.

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