But it should also work with the Iomega Jaz Traveller parallel to SCSI interface. .Pp The driver has been extended to the ZIP+ drive which is based on the Iomega Matchmaker Parallel to SCSI interface. .Sh USAGE The driver should let you use a printer connected to the drive while transferring data. .Pp DOS, .Dx or .Fx filesystems are supported. When mounting a DOS filesystem or formatting a .Dx or .Fx filesystem, 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:\\ :pb#196608:ob#0:bb#4096:fb#512:\\ :pc#196608:oc#0:bc#4096:fc#512: .Ed .Pp and use .Xr disklabel 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 SEE ALSO .Xr da 4 , .Xr lpt 4 , .Xr ppbus 4 , .Xr ppc 4 , .Xr scsi 4 .Sh HISTORY The .Nm manual page first appeared in .Fx 3.0 . .Sh AUTHORS This manual page was written by .An Nicolas Souchu . .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.
