|
|
.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
|
|
formating 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:\\

.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 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.
