- .Sh NAME
- .Nm vpo
- .Nd parallel to SCSI interface driver
- .Sh SYNOPSIS
- .Cd "device vpo"
- .Pp
- For one or more SCSI busses:
- .Cd "device scbus"
- .Sh DESCRIPTION
- The
- .Nm
- driver provide access to parallel port Iomega Zip and Jaz drives.
- .Sh HARDWARE
- The
- .Nm
- driver supports the following parallel to SCSI interfaces:
- .Pp
- .Bl -bullet -compact
- .It
- Adaptec AIC-7110 Parallel to SCSI interface (built-in to Iomega ZIP
- drives)
- .It
- Iomega Jaz Traveller interface
- .It
- Iomega MatchMaker SCSI interface (built-in to Iomega ZIP+ drives)
- .El
- .Sh USAGE
- The driver should let you use a printer connected to the drive while
- transferring data.
- .Pp
- DOS and
- .Fx
- file systems are supported.
- When mounting a DOS file system or
- formatting a
- .Fx
- file system, check the slice of the disk with the
- .Xr fdisk 8
- utility.
- .Pp
- In order to unixify a ZIP disk, put the following in /etc/disktab:
- .Bd -literal
- 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:
- .Ed
- .Pp
- and use
- .Xr bsdlabel 8 .
- .Pp
- If you have trouble with your driver, your parallel chipset may not run
- properly at the detected mode (NIBBLE, PS2 or EPP).
- Tune the
- .Xr ppc 4
- bootflags to force other modes.

- .Sh HISTORY
- The
- .Nm
- manual page first appeared in
- .Fx 3.0 .
- .Sh AUTHORS
- This
- manual page was written by
- .An Nicolas Souchu .
- .Sh 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.
