VPO(4) BSD 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:
· 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 formating 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.

The vpo manual page first appeared in FreeBSD 3.0.

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.
