VPO(4) BSD Kernel Interfaces Manual VPO(4)
vpo -- parallel to SCSI interface driver
For one or more SCSI busses:
The vpo driver provide access to parallel port Iomage Zip and Jaz drives.
The vpo driver supports the following parallel to SCSI interfaces:
o Adaptec AIC-7110 Parallel to SCSI interface (built-in to Iomega ZIP
o Iomega Jaz Traveller interface
o Iomega MatchMaker SCSI interface (built-in to Iomega ZIP+ drives)
The driver should let you use a printer connected to the drive while
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:
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.
da(4), lpt(4), ppbus(4), ppc(4), scsi(4)
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.
The vpo manual page first appeared in FreeBSD 3.0.
