-
-!!1. Introduction
-
-
-The Iomega ZIP drive is a popular, removable media disk drive.
-It is avaliable in several versions.
-
-
-* Parallel Port
-*
-
-* SCSI
-*
-
-* IDE - ATAPI
-*
-
-* Plus
-*
-
-The most popular seems to be the Parallel port version. It has been
-around a long time and it is low cost. The SCSI version has also been
-around for a while but it needs a scsi card that many people do not have
-already, so it it not quite as popular. The ATAPI version now seems
-to be more available. The Plus is the newer version of the ZIP drive.
-It has the capability to detect what port its plugged into, scsi or
-parallel. This document will focus on the Parallel port version, but
-also offer some tips for other versions.

-
-!!2. Quick Start
-
-
-OK so you have purchased a new zip drive and now you want to use it.
-Some distributions have the modules already built. You can try insmod ppa
-for starters. (Make sure you have it hooked up and a disk inserted).
-If the ppa program is not there, then configure the kernel.
-My machine has 2 parallel ports, one for the zip and one for the printer.
-This makes things easy, no cable switching.
-
-
-Configure the kernel:
-
-
-* cd /usr/src/linux
-*
-
-* make xconfig
-*
-
-* scsi support = Y
-*
-
-* scsi disk support = Y
-*
-
-* Iomega zip support as a module
-*
-
-* printer support also as a module
-*
-
-* save it and exit
-*
-
-* make dep
-*
-
-* make clean
-*
-
-* make zImage or zlilo or zdisk
-*
-
-* make modules
-*
-
-* make modules_install
-*
-
-
-
-Now to use the drive:
-
-
-* load the module insmod ppa
-*
-
-* build a mounting point. mkdir /zip
-*
-
-* insert a preformatted windoze type disk into the drive.
-*
-
-* mount the disk. mount -t vfat /dev/sda4 /zip
-*
-
-* use any standard file commands as in l /zip, ls /zip, df, cp,
-*
-
-* when you are finished umount /zip
-*
-
-
-
-If you had trouble with any of the previous steps, see the following
-sections for more detailed instructions.
-
-
-

-
-!!3. Configuring a kernel for the ZIP drive
-
-
-To use the ZIP drive with Linux, you must have a kernel configured
-with support for the SCSI system, support for SCSI disks, and support
-for the host adapter you are using. If you are not familiar with
-building a kernel, you should read up on the
-Linux Kernel HOWTO for information.
-
-
-You must begin the process of building a kernel with the configuration
-step. Here, you identify the specific kernel components that you
-need. First step cd /usr/src/linux. There are several
-ways to actually do the configuration. Under X windows I use
-__make xconfig__. There is also make menuconfig
-or make config for command line prompts. The easiest way
-is with xconfig.
-
-
-In the section __SCSI Support__ set __SCSI support = Y__.
-Also set __SCSI disk support = Y__.
-
-
-In the section __SCSI low-level drivers__ you want to set
-__IOMEGA Parallel Port ZIP drive SCSI support = M__. The M
-stands for modules.
-
-
-In the section __Character Devices__ find and set
-__Parallell Printer support = M__
-
-
-If you are a bit unsure about any of this, use zdisk for the make
-step. This will build and install the kernel to floppy. If you
-screw it up somehow, you still have a good bootable system on the hard
-drive.
-
-
-Now build the kernel with these steps:
-
-
-* make dep
-*
-
-* make clean
-*
-
-* make zImage or zlilo or zdisk
-*
-
-* make modules
-*
-
-* make mdoules_install
-*
-
-
-
-__hint__ if you want to create an output log of the make zImage
-step you can use
-
-
-make zImage 2>&1 | tee zImage.out
-
-
-This is really
-a good thing to do, if you have compile errors or other conflicts
-in the configuration, now you have a file with the error messages or
-compile errors. This makes asking for help much easier.
-
-
-You also need to load the modules somewhere. On my system I just added
-a couple of lines to the boot.local file.
-
-
-* insmod ppa
-*
-
-* insmod lp
-*
-
-My system is Suse 5.3 and this file is in /etc/rc.d. The location of this
-file will vary by distribution, but there will be a file somewhere, for
-local changes to be made at start up time. You should use the file that
-is applicable for your distribution.
-
-
-Now shutdown and reboot.
-
-
-You can also build all or part of the SCSI system as modules. If you
-do this, be sure to load scsi.o, then sd.o and finally the driver for
-your host adapter, before you try to access the ZIP drive.
-
-
-
-
-!!3.1 SCSI version
-
-
-
-
-
-
-If you already have a SCSI disk in your system, and you are connecting
-the ZIP drive to the same controller, there is no additional kernel
-configuration required. Otherwise, you will most likely have to build
-a new kernel.
-
-
-If you are building a kernel to support the SCSI version of the ZIP
-drive, you should select SCSI support and SCSI disk support. You must
-also select a driver for the interface card you will use. If you have
-a ZIP Zoom, select the aha152x driver.
-
-
-Be sure to read the documentation for your adapter in the SCSI HOWTO
-and any README files in the drivers/scsi subdirectory of the Linux
-source tree. Pay attention to command line parameters that you might
-have to use to help the kernel initialise your adapter.
-
-
-For instance, if you are using the ZIP Zoom card, you will have to add
-something like
-
-
-
-
-
-aha152x=0x340,11,7,1
-
-
-
-
-to the boot command (or include it in your /etc/lilo.conf file in an
-append clause). This tells the driver the port address and IRQ of
-your ZIP Zoom card - be sure to use the numbers that correspond to the
-way your jumpers are set.
-
-
-You should also read Paul Gortmaker's
-BOOTPROMPT HOWTO for information
-about configuring your kernel with LILO or LOADLIN.
-
-
-
-
-
-
-
-

-----
-
-!!4. The ZIP drive
-
-
-There are at least five or six versions of the Iomega ZIP 100 drive.
-The Iomega page for these drives is at
-http://www.iomega.com/product/zip/
-They all accept
-special cartridges resembling a 3.5" floppy disk that hold 100
-megabytes of data. The disks actually hold 96 cylinders of 2048
-sectors each holding 512 bytes. This would normally be called 96
-Megabytes.
-
-
-The external drive comes in these types:
-
-
-* Parallel port
-*
-
-* SCSI
-*
-
-* Plus
-*
-
-
-
-The internal drive comes in these types:
-
-
-* SCSI
-*
-
-* IDE
-*
-
-* ATAPI
-*
-
-
-
-The internal versions can be mounted in 3.5 or 5.25 drive slots.
-The external versions are in a small blue plastic case enclosure,
-powered by an external wall brick.
-
-
-All the drives have a large pushbutton on the front of the drive.
-This is used to eject the disk. Linux locks the door while using the
-drive, but if the button is pressed while the door is locked, the ZIP
-drive will remember and eject the disk as soon as the software unlocks
-it.
-
-
-
-
-!!4.1 Parallel port version Zip100
-
-
-
-This drive is described at
-http://www.iomega.com/product/zip/zippp.html
-
-The Linux driver comes in a couple of different versions. The .26
-version of the ppa.c program ships standard with the 2..x kernels.
-If your kernel is older than 2..35 then you have the __OLD__
-program.
-Check out
-
-
-
-David Campbell's page
-for the more current version of this program. At the time of this
-writing the current version is 1.42.
-
-
-The auto configuration features of the 1.4x program are very nice.
-You do NOT have to tell the progam what the base address of the parallel
-port is. The program will prob the standard address's for the parallel
-ports and attach the drive when it finds it.
-
-
-The most common problem is to load the lp printer module before the ppa program.
-The ppa program must be loaded before the lp module. The lp module will tie
-up the port that the zip drive needs, this is why the ppa progam must be loaded
-first.
-
-
-Also be sure that all cables are firmly attached.
-
-
-If you did everything right :) you will see messages like this at boot time.
-
-
-
-

-
-
-You can view these messages with dmesg | more.
-You can save the messages to a file with dmesg > dmesg.txt.
-This is often usefull if you are trying to debug the installation.
-
-
-Also see section
-Getting more information
-
-
-
-
-
-
-!!4.2 SCSI external version
-
-
-
-This drive is described at
-http://www.iomega.com/product/zip/zipscsi.html
-
-The external SCSI version of the ZIP drive has two DB25F connectors,
-and two configuration switches. One switch selects the drive's target
-address. The choice is limited to target 5 or 6. The other enables an
-internal terminator, in case the drive is the last one on a chain.
-The 25 pin SCSI connectors use the familiar Macintosh style wiring.
-The drive is shipped with a Macintosh type cable, but standard cables
-and converters are easily obtained if you are using a host adapter
-with a Centronics or high-density connector.
-
-
-I have not seen an internal SCSI drive, but I would expect it to have
-a standard 50 pin DIP header SCSI connector and the same two switches.
-
-
-Make sure that the target address you choose does not conflict with
-any other SCSI devices you may have on the same bus. Also be sure
-that the physically last drive in a chain has termination enabled, or
-an external terminator installed.
-
-
-If you have an internal SCSI disk or CD-rom, and you connect your ZIP
-drive to the existing adapter, you should check to see if there are
-any terminators on the card that must be removed. Only the two
-extreme ends of the SCSI bus should be terminated. If your bus is
-partly internal and partly external, there should be one terminator on
-the last external device and one on the last internal device, but no
-terminators on the adapter card itself.
-
-
-Be sure that all cables are firmly attached.
-
-
-The kernel configuration is much the same as the internel version. See the
-next section SCSI Internal version for an example configuration.
-
-
-
-
-!The ZIP ZOOM host adapter
-
-
-Iomega markets a SCSI host adapter under the name ZIP Zoom. This is
-actually based on the design of the __Adaptec AHA1520__ family of
-adapters. It has an external Macintosh type DB25F connector,
-compatible with the cable that comes with the ZIP drive.
-
-
-Linux supports this adapter with the __aha152x__ driver.
-
-
-
-
-!!4.3 The SCSI Internal version
-
-
-
-
-
-
-Install hardware as described in the "Installation and Reference Guide"
-noting which SCSI ID, IRQ and I/O Port Address are being used. (You'll need
-this info later.) Things will go smother if the drive and adapter card use
-different SCSI ID's.
-
-
-__Beware__ The zip zoom card is hardwired for scsi ID number 7. The scsi
-id in the command line below is for the card, not the drive. The card and the
-drive must use different scsi id numbers. For example if the card uses 7 then
-use 5 or some other number for the drive.
-
-
-Recompile the kernel after configuring it to include 'SCSI', 'SCSI disk'
-and 'AHA152X/2825' support. INSTALL NEW KERNEL :-(
-
-
-Determine what your kernel command line is:
-
-
- aha152x=[[I/O Port][[,IRQ][[,SCSI ID][[,RECONNECT][[,PARITY]
-
-
-For example :
-
-
- aha152x=0x140,10,7,1
-
-
-If your using LILO add your kernel command line to your lilo.conf file
-using the append command.
-
-
-(ie. append = "aha152x=0x140,10,7,1")
-
-
-If your using LOADLIN add your kernel command line to the command you use to
-initiate loadlin.
-
-
-
-
-(ie. loadlin c:\vmlinuz root=/dev/hda3 aha152x=0x140,10,5,1 ro)
-
-
-
-
-
-
-
-
-!!4.4 The ZIP Plus - IMM driver
-
-
-
-This drive is described at
-http://www.iomega.com/product/zip/zipplus.html
-
-This is a __newer__ version of the external Zip drive. The
-__ Zip Plus __ does not use the ppa driver, instead it uses the
-__ imm __ driver.
-Philippe Andersson
-sent in this excellent section on the imm driver for the Zip Plus.
-Thanks Philippe.
-
-
-First, rebuild your kernel to include the following items:
-
-
-
-
-
-*modules support
-*
-
-*SCSI support
-*
-
-*SCSI Disk support
-*
-
-*lp as a module (if you need it)
-*
-
-
-
-You'll notice we didn't select any SCSI low-level driver. That's ok --
-we'll build it separately later.
-
-
-Then, you need to get the driver source code from Dave Campbell's home
-page (
-http://www.torque.net/~campbell/imm.tar.gz). Version .18 is
-the current one at the time of writing (Aug. 98). Unzip it and untar
-it somewhere (under /usr/src, for instance). Then just run
-make. You'll get the module you need (imm.o). Copy
-it to
-
-/lib/modules/$(uname -r)/scsi
-
-.
-
-
-If your lp module was loaded (check with __lsmod__(1)), unload it
-(rmmod lp), then load imm.o (insmod imm)
-and you're all set basically.
-
-
-If the ZIP drive was not connected and powered on at the time, you'll
-get the message "init_module: Device or resource busy", and the module
-won't load. (By the way, it looks like you don't need to switch your
-PC off to connect the ZIP -- just make sure the module is not loaded
-and the drive is turned off, then plug it in, turn the drive on, and
-load the module.)
-
-
-If the ZIP was connected and powered on, but there was no disk in, the
-module will load all right, but you'll get the message that it can't
-read the disk partition table. This is ok, as the partition table will
-be automatically read when you insert a ZIP disk.
-
-
-If there was a ZIP disk in, you'll get the full information displayed,
-including a list of partitions defined on the disk and its Write
-Protect status. Here is a sample load-time message:
-
-
-
-
-vger:~# insmod imm

-imm: ECP with a 16 byte FIFO present
-imm: PS/2 bidirectional port present
-imm: Passed Intel bug check.
-imm: Probing port 0278
-scsi0 : Iomega ZIP Plus drive

-SCSI device sda: hdwr sector= 512 bytes. Sectors= 196608 [[96 MB] [[.1 GB]
-sda: Write Protect is off
-sda: sda1
-vger:~#
-
-
-
-One last remark to mention that this version of the driver also locks
-the drive door while the disk is mounted. If the eject button is
-pressed in this situation, nothing happens, but the drive "remembers"
-and ejects the disk as soon as it is dismounted.
-
-
-
-
-
-
-
-
-
-
-!!4.5 ATAPI version
-
-
-
-This drive is described at
-http://www.iomega.com/product/zip/zipatapi.html
-
-There was an IDE version of the drive produced for a while.
-I think that for the most part this has been replaced by
-the ATAPI version.
-
-
-Donald Stidwell sent in these comments on the ATAPI version. Thanks Don.
-
-
-I use an ATAPI Zip drive and it works with both 2..32 and 2..33
-kernels. I've used it under both RH 5.0 and !OpenLinux 1.2 (my current
-used distribution). To get it to work under !OpenLinux, I just enabled
-__ATAPI floppy support__ in the kernel. !OpenLinux does not have this
-support compiled in by default.
-
-
-No other drivers are needed. It will mount as an extended partition on
-partition 4. I.E, mine mounts on HDB4. I mount it under /mnt/zip as
-noauto, although I don't suppose there would be any real problem with
-automounting. I just wonder about ejecting disks. I always dismount
-the drive before ejecting a cartridge.
-
-
-There are more detailed instructions for the ATAPI install in the Linux
-Gazette May 1998 issue. See the 2 cent tip section.
-
-
-
-
-<url url="http://www.linuxgazette.com/issue28/lg_tips28.html#atapi">
-
-
-
-
-
-!!4.6 IDE version
-
-
-
-
-I have not used the IDE version. Eric Backus sent in these comments.
-Thanks Eric.
-
-
-I have one of these. It came with my Gateway 2000 computer a year ago.
-I think most of these were shipped by large OEM companies like this,
-before the ATAPI version of the ZIP drive was available.
-
-
-The good news about this drive: no kernel modules or modifications are
-needed to support it. It looks to the kernel like an IDE hard drive.
-It worked for me with no effort with kernel 2..31 and 2..32.
-
-
-The bad news about this drive: because it doesn't use ATAPI, you can't
-use the SCSI-to-ATAPI translation, which means you can't use mtools to
-write-protect disks (or to eject them, for that matter).
-
-
-
-
-
-
-
-!!4.7 USB version
-
-
-
-This drive is described at
-http://www.iomega.com/product/zip/imac.html
-
-These drives look very cool and the USB interface also looks good. The
-only problem is that the USB interface for Linux is still under
-development at this time. So for now, this drive is not usable
-under Linux. Check this address for updates.
-
-
-

-
-
-
-!!4.8 ZIP250 version
-
-
-
-This drive is desribed at
-http://www.iomega.com/product/zip/zip250.html
-
-This drive is new as of January 1999. I just bought one of these and it works
-very well in Linux. Just use the IMM driver from
-http://www.torque.net/~campbell/imm.tar.gz
-Set up the driver the same way as the zip plus. Mainly just download the
-driver, unpack it, and run make. Then copy the imm.o executable to the modules
-directory. For example /lib/modules/2..35/scsi (The 2..35 is your
-kernel version). If you are not sure of the version do uname -r.
-
-
-

-
-!!5. Troubleshooting Install
-
-
-If you get errors while giving insmod ppa as given below:
-----
-
-root# insmod ppa
-Using /lib/modules/version/kernel/drivers/scsi/ppa.o
-/lib/modules/version/kernel/drivers/scsi/ppa.o: unresolved symbol parport_register_device_Rf274b881/lib/modules/version/kernel/drivers/scsi/ppa.o: unresolved symbol parport_unregister_device_Rb0814cd3

-/lib/modules/version/kernel/drivers/scsi/ppa.o: Note: modules without a GPL compatible license cannot use GPLONLY_ symbols
-
-----
-
-
-The problem is that you did not add a printer to your system in 'Printer Configuration'.
-Before you do 'insmod ppa' you MUST add a printer. Click on
-KDE-Start-Button->System->Printer-Config and add a printer by name
-'sometestprinter' using /dev/lp0 (or lp1, lp2 check the output from dmesg | more).
-Now, test the printer which you added by giving:
-''/etc/rc.d/init.d/lpd restart ''. If the lpd daemon starts then the printer is
-configured properly. Now try
-
-
-
-----
-
-bash# insmod ppa
-bash# insmod lp

-!!6. Using the ZIP drive
-
-
-If you have built in all the required components, the kernel should
-recognize your adapter and drive at boot time. If you are using a
-loadable module for your driver, the following discussion applies once
-that module is loaded.
-
-
-For the most part, the SCSI and parallel versions of the drive behave
-identically, except that the parallel version is somewhat slower.
-
-
-
-
-
-
-
-!!6.1 Fdisk, mke2fs, mount, etc.
-
-
-
-Once you know the drive name for your ZIP drive, you are set. You can
-manipulate the drive with the normal Linux disk management commands.
-fdisk (or perhaps cfdisk) is used to manipulate the partition tables
-on the disk. mke2fs can be used to format a partition with the ext2
-filesystem - the one most commonly used in Linux. mount is used to
-connect a formatted partition into your directory hierarchy.
-
-
-You should study the manual pages for these tools if you are not
-familiar with them. Be warned that there are now several quite
-different versions of the fdisk program - be careful.
-
-
-I'll describe two common scenarios.
-
-
-
-
-!!6.2 An existing DOS formatted disk
-
-
-
-If you have a ZIP disk with a DOS file structure that was originally
-created by Iomega's tools, the partition scan should say that the disk
-has one partition, /dev/sda4.
-
-
-You should make a place to mount the disk, lets say /zip, and then
-mount it as an MS-DOS filesystem:
-
-
-
-
-
-mkdir /zip
-mount -t vfat /dev/sda4 /zip
-
-
-
-
-You could also use msdos instead of vfat. vfat supports long filenames
-where msdos does not.
-Now, the files on the disk should appear in /zip. While the disk is
-mounted, you will not be able to remove it. When you are finished
-with the disk you can umount it to release it and detach it from your
-directory hierarchy.
-
-
-
-
-
-umount /zip
-
-
-
-
-Once you've made the /zip mount point - you don't need to do it again,
-so you could come back later and mount something else there.
-
-
-
-
-!!6.3 Re-format as a native Linux disk
-
-
-
-
-
-
-If you want to erase a ZIP disk and make a Linux native file system on
-it. You should use fdisk on the entire disk:
-
-
-
-
-
-fdisk /dev/sda
-
-
-
-
-and delete any existing partitions (with the d command). Then create
-a new partition with the n command, make it primary partition number
-1, use w to write the partition table to disk, and quit with
-q.
-
-
-Format the partition
-
-
-
-
-
-mke2fs /dev/sda1
-
-
-
-
-(The 1 is the number that you gave this partition in fdisk). Now you
-can mount the disk:
-
-
-
-
-
-mount -t ext2 /dev/sda1 /zip
-
-
-
-
-(re-using that mount point we created before).
-
-
-
-
-!!6.4 fstab entries
-
-
-
-The /etc/fstab allows you to configure the mount command. I like to
-be able to mount and write to the zip disk from any login id on the
-system. I added 2 lines to the end of the fstab file that look like this.
-
-
-
-
-/dev/sda1 /zip ext2 noauto,rw,user,nosuid,sync
-/dev/sda4 /zipdos vfat noauto,rw,user,nosuid,sync,mode=0777
-
-
-
-These entries assume that you have a /zip and a /zipdos directory. If
-you want all users ids to read and write, make sure you set the permissions.
-For exmaple __ chmod 666 /zip __. You must do the chmod as root.
-The fstab entries also assume that your dos disks are partitioned as 4
-(sda4 in my case), and the ext2(linux) disks are partitoned as 1 (sda1).
-You can read more about the fstab options with __man mount__
-
-
-With the fstab entries as above you can mount a dos disk with
-__ mount /zipdos __
-If you are using a linux ext2 disk then use the command
-__ mount /zip __
-
-
-
-
-
-
-
-!!6.5 The ZIP Tools disk
-
-
-
-
-
-
-There is some extra work to be done if you want to use the disk that
-comes with the ZIP drive. As shipped, the software controlled write
-protection is enabled. Most people have unlocked the disk under DOS
-before ever trying to use it with Linux. Linux cannot access a locked
-disk, and it must be unlocked with Iomega's tools.
-
-
-A native Linux program to manage the write protection feature, among
-other things, is expected to be available soon.
-
-

-
-!!7. Performance
-
-
-With the standard version of the 2..x kernels you get the .26 version
-of the ppa.c program. This is a very reliable simple program. It
-has gotten a lot of use and abuse and held up rather well. The only bad
-thing about this program is that it's not very fast. On my machine I have
-version 2..30 kernel, and 2 parallel ports. This is also a low-buck
-machine pentium 133 - 16 meg memory, 5 gig maxtor eide hard drive. The machine
-cost me 500. U.S. Dollars and the drive was 250. I am cheap but so what.
-
-
-I had the ZIP drive on
-the second port and the printer on the first port. The second port
-was an old add in card, no epp mode. This made the driver run in 4 bit mode.
-
-
-To base line the performance I copied the netscape tar file from the hard
-drive to the zip drive. This file is about 10.6 meg.
-Time 7 minutes 15 seconds. Going from the zip
-drive to the hard drive was about 7 minutes even. Not exactly setting the
-world on fire.
-
-
-I then made 2 changes. First I switched the ZIP drive to the first
-port and went into the bios and set EPP mode on for the first port.
-At the same time I hooked up the printer to the 2nd port.
-
-
-Second change I went out and downloaded the new version of the program
-from
-David Campbells page
-Then I installed this program. Check out
-the readme file that is included.
-
-
-Then I ran the same test again of copying the Netscape tar file to and
-from the ZiP drive. The copy to the C drive was 1:55 seconds. From the
-hard drive to the Zip drive was 1 minute flat. This compares to 7:15 and 7:00
-with the old program. This was a big improvement over the .26 program.
-This was also using the zip drive as a vfat file type.
-
-
-Next I formated a zip drive in ext2 format. Ran the same test again.
-The copy going to the hard drive was only 50 seconds. The copy from the
-hard drive to the Zip drive was only 40 seconds.
-
-
-__ Performance Summary __
-
-
-For this test case of moving a 10.6 meg file,
-the 4 bit standard port mode and program version .26 is the slowest
-7:00 and 7:15
-
-
-The new program (1.41) and EPP mode with ext2 file types is the fastest
-at 50 seconds and 40 seconds.

-!!8. Frequently asked questions
-
-
-These are some of the questions that we get asked a lot. Please read
-the answers
here before asking them again !
-
-
-
-
-!!8.1 Can I plug a printer into the parallel ZIP drive ?
-
-
-
-Yes, but. Currently, you cannot have both the lp and ppa drivers
-active on the same parallel port. A resource sharing protocol has
-been designed and is in the early stages of implementation, but will
-not be available before Linux 2.0 is released.
-
-
-If you like living on the bleeding edge of things, get the 2.1.x
-kernel and you can have port sharing. See
-http://www.cyberelk.demon.co.uk/parport.html
-
-
-The easy way to do this with 2..x kernel is to have 2 parallel ports.
-I bought my second one for about 15 dollars and it works great.
-You can use one for
-printing and one for your ZIP drive. Just build a kernel with both
-the lp and ppa drivers as modules. I use the newer (1.41) version of
-ppa, so I just load ppa first (insmod ppa). It then finds the zip drive
-on the first port. Then I load lp (insmod lp) and it assigns the printer
-to the second port.
-
-
-If you use the .26 version of the program then upgrade to 1.41 or newer.
-The only answer you will get on qustions about this driver is to
-upgrade the program.
-
-
-
-
-!!8.2 Do you plan to support EPP/ECP ports in PPA ?
-
-
-
-
-
-
-Version .26 of the program does not support EPP. Version 1.41 __does__
-support the EPP. This program is also much faster. See the performance
-section for more details.
-
-
-
-
-!!8.3 Can I run Linux from a ZIP drive ?
-
-
-
-People have done this. It would seem this might make a great rescue disk or a
-way to test an install.
-
-
-
-http://metalab.unc.edu/LDP/HOWTO/mini/ZIP-Install.html
-
-
-
-
-
-
-!!8.4 Can I boot from the ZIP drive ?
-
-
-
-This depends on what you are using for a host adapter. If your host
-adapter has a BIOS ROM with code that can boot from target 5 or 6,
-then yes, you can boot from the SCSI ZIP drive. You cannot boot from
-a parallel port drive.
-
-
-If you have DOS on your main disk and want to boot Linux from a ZIP
-disk, you can do this using the LOADLIN boot loader. Your kernel
-image must be somewhere on the DOS disk, but the rest of your Linux
-system could be on the ZIP. Make sure that the kernel you use has the
-correct drivers built in.
-
-
-As far as I am aware, there are no installation boot floppies for any
-of the popular distributions that contain the parallel ZIP driver.
-
-
-
-
-!!8.5 Why does Iomega use partition number 4 ?
-
-
-
-This is one of the most popular questions, but I don't think anyone
-has a definite answer to this one. Could be they had their head
-where the sun don't shine. Maybe there is no reason.
-
-
-
-
-!!8.6 How can I have the disk mounted at boot time ?
-
-
-
-All you need to do is to add a line to your /etc/fstab file. For
-instance, if you will always have a DOS disk in the drive when you
-boot, you could put
-
-
-
-
-
-/dev/sda4 /zip vfat defaults 0
-
-
-
-
-in the fstab. Depending on your distribution, the initialization
-scripts might try to run fsck on partitions listed in your fstab. Be
-aware that this could cause problems if you forget to put the disk in
-the drive when you boot, or have the wrong disk there.
-
-
-
-
-!!8.7 What happens if there is no disk inserted when I boot ?
-
-
-
-The kernel will try to read the partition table, but the operation
-will time out. There is nothing to worry about. Once you have
-inserted a disk, and try to do something with it the kernel will
-notice that there is a disk there now and rescan the partition table.
-
-
-HINT: when you change disks, it is a good idea always to use fdisk to
-check the partition structure on the new disk.
-
-
-The BIOS on some SCSI host adapters will attempt to read the partition
-table on your disk during the system boot. If you cannot disable this
-check, you may be forced always to boot with a disk in the drive.
-
-
-
-
-!!8.8 Can I use the parallel drive as a real SCSI disk ?
-
-
-
-The PPA-3 parallel-to-SCSI adapter is implemented as a single ASIC
-chip that Iomega calls a VPI0. It is embedded on the ZIP drive's
-controller card. There is an actual SCSI bus present, but not in a
-useful form.
-
-
-Although I haven't tried to compare the two cards, it seems logical
-that the VPI0 replaces the conventional electrical buffering circuits
-that would be required if the SCSI bus were extended outside the
-package.
-
-
-
-
-
-
-
-!!8.9 Can PPA be used with Iomega's parallel port tape drives ?
-
-
-
-No. Those drives are floppy-tape drives. There is no SCSI involved.
-
-
-Several people have indicated an interest in applying my methods to
-try to determine the protocol and develop a driver for these tapes.
-The first step in that process is to get the DOS driver working under
-DOSemu. I have not yet heard that anyone has been successful in doing
-it.
-
-
-
-
-!!8.10 Will PPA work with the parallel port !SyQuest EZ135 ?
-
-
-
-No. The EZ135 is an IDE drive with a !ShuttlePort parallel to IDE
-converter embedded in it.
-
-
-However there has been some work done on this driver. Check out
