33 .Nd parallel to SCSI interface driver
37 For one or more SCSI busses:
38 .Cd "device scbus0 at vpo0"
40 The primary purpose of the
42 driver is to provide access to the Adaptec AIC-7110 SCSI controller built
43 in the Iomega ZIP drive.
44 But it should also work with the Iomega Jaz Traveller
45 parallel to SCSI interface.
47 The driver has been extended to the ZIP+ drive which is based on the
48 Iomega Matchmaker Parallel to SCSI interface.
50 The driver should let you use a printer connected to the drive while
55 filesystems are supported.
56 When mounting a DOS filesystem or
59 filesystem, check the slice of the disk with the
63 In order to unixify a ZIP disk, put the following in /etc/disktab:
66 :ty=removable:se#512:nc#96:nt#64:ns#32:\\
67 :pa#196608:oa#0:ba#4096:fa#512:\\
68 :pb#196608:ob#0:bb#4096:fb#512:\\
69 :pc#196608:oc#0:bc#4096:fc#512:
75 If you have trouble with your driver, your parallel chipset may not run
76 properly at the detected mode (NIBBLE, PS2 or EPP). Tune the
78 bootflags to force other modes.
86 During boot, the driver first tries to detect a classic ZIP, then a ZIP+.
87 The ZIP+ detection is intrusive and may send errorneous charaters to your
88 printer if the drive is not connected to your parallel port.
