NAME    [Toc]    [Back]

     vpo -- parallel to SCSI interface driver

SYNOPSIS    [Toc]    [Back]

     device vpo

     For one or more SCSI busses:
     device scbus

DESCRIPTION    [Toc]    [Back]

     The primary purpose of the vpo driver is to provide access to the Adaptec
     AIC-7110 SCSI controller built in the Iomega ZIP drive.  But it should
     also work with the Iomega Jaz Traveller parallel to SCSI interface.

     The driver has been extended to the ZIP+ drive which is based on the
     Iomega Matchmaker Parallel to SCSI interface.

USAGE    [Toc]    [Back]

     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:\

     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.

SEE ALSO    [Toc]    [Back]

     da(4), lpt(4), ppbus(4), ppc(4), scsi(4)

BUGS    [Toc]    [Back]

     During boot, the driver firstly try 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.
