Usage

Overview

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

Deprecation notice

The vpo driver is not present in FreeBSD 13.0 and later.

Hardware

The vpo driver supports the following parallel to SCSI interfaces:

• Adaptec AIC-7110 Parallel to SCSI interface (built-in to Iomega ZIP drives)

• Iomega Jaz Traveller interface

• 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 gpart(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.
