2 Linux and parallel port IDE devices
5 PARIDE v1.03 (c) 1997-8 Grant Guenther <grant@torque.net>
10 Owing to the simplicity and near universality of the parallel port interface
11 to personal computers, many external devices such as portable hard-disk,
12 CD-ROM, LS-120 and tape drives use the parallel port to connect to their
13 host computer. While some devices (notably scanners) use ad-hoc methods
14 to pass commands and data through the parallel port interface, most
16 a parallel-port adapter chip added in. Some of the original parallel port
18 (The Iomega PPA-3 adapter used in the ZIP drives is an example of this
20 The adapter chip reproduces a small ISA or IDE bus in the external device
26 which is then connected to a floppy-tape mechanism. The vast majority
27 of external parallel port devices, however, are now based on standard
28 IDE type devices, which require no intermediate controller. If one
29 were to open up a parallel port CD-ROM drive, for instance, one would
30 find a standard ATAPI CD-ROM drive, a power supply, and a single adapter
31 that interconnected a standard PC parallel port cable and a standard
32 IDE cable. It is usually possible to exchange the CD-ROM device with
33 any other device using the IDE interface.
35 The document describes the support in Linux for parallel port IDE
36 devices. It does not cover parallel port SCSI devices, "ditto" tape
38 parallel port IDE subsystem, including:
40 - MicroSolutions backpack CD-ROM
41 - MicroSolutions backpack PD/CD
42 - MicroSolutions backpack hard-drives
43 - MicroSolutions backpack 8000t tape drive
44 - SyQuest EZ-135, EZ-230 & SparQ drives
45 - Avatar Shark
46 - Imation Superdisk LS-120
47 - Maxell Superdisk LS-120
48 - FreeCom Power CD
49 - Hewlett-Packard 5GB and 8GB tape drives
50 - Hewlett-Packard 7100 and 7200 CD-RW drives
52 as well as most of the clone and no-name products on the market.
54 To support such a wide range of devices, PARIDE, the parallel port IDE
58 high-level drivers for each of the different types of supported devices:
61 pd IDE disk
62 pcd ATAPI CD-ROM
68 (Currently, the pg driver is only used with CD-R drives).
70 The high-level drivers function according to the relevant standards.
71 The third component of PARIDE is a set of low-level protocol drivers
72 for each of the parallel port IDE adapter chips. Thanks to the interest
77 aten ATEN EH-100 (HK)

83 fit2 FIT TD-2000 (US)
84 fit3 FIT TD-3000 (US)

100 In either case, you will need to select "Parallel port IDE device support"
101 as well as at least one of the high-level drivers and at least one
102 of the parallel port communication protocols. If you do not know
103 what kind of parallel port adapter is used in your drive, you could

120 MicroSolutions hard-drive pd bpck
126 FreeCom CD-ROM pcd frpw

149 a parallel port IDE adapter. Once it finds one, the probe stops. So,
151 how to identify them. This requires specifying the port address, the
171 with unit ID number 36 connected to the parallel port at 0x378, a SyQuest
172 EZ-135 connected to the chained port on the PD/CD drive and also an
173 Imation Superdisk connected to port 0x278. You could give the following
179 is the parallel port base address, the 0 is the protocol registration
183 PARPORT parallel port sharing system that is included by the
184 "Parallel port support" option, PARPORT must be included and enabled
185 if you want to use chains of devices on the same parallel port.
188 ----------------------------------------------
220 Finally, you can load high-level drivers for each kind of device that
223 individual co-ordinates when you load the driver.
225 For example, if you had two no-name CD-ROM drives both using the
226 KingByte KBIC-951A adapter, one on port 0x378 and the other on 0x3bc
231 For most adapters, giving a port address and protocol number is sufficient,
236 a SyQuest EZ-135 is attached to port 0x378::

262 # mkd -- a script to create the device special files for the PARIDE subsystem
288 like any other Linux device. For example, to mount a CD-ROM in pcd0, use::
295 fdisk /dev/pda -- make a new partition table with
298 mke2fs /dev/pda1 -- to build the file system
300 mkdir /shark -- make a place to mount the disk
