This is my first howto! Give me a round of applause =D>

Before I go on, I'd just like to say that Google is really your friend, and there's two sources that I got information from. I will share them here:

From these two sources and some tinkering, you should be able to get almost any external parallel drive working in Ubuntu!

Also, this Howto is made for Ubuntu 8.04 Hardy Heron. So let's get started!

================================================== ========

First, you need to write a script to get the parallel drivers loaded up. This should work with all Syquest drives.

Open up gedit (either type in gedit in a terminal, or click Applications -> Accessories -> Text Editor)

copy and paste the following into the text file:
# Start here...

# modprobe parport # Already maybe loaded
# modprobe parport_pc # Already maybe loaded

modprobe paride

# The following 2 steps are not necessary on Breezy...
# mkdir /lib/modules/$(LINUX_VERSION)/misc
# cp /lib/modules/$(LINUX_VERSION)/kernel/drivers/block/paride/epat.o /lib/modules/2.4.20-20.8/misc/epat.o

echo "Inserting the necessary modules..."
modprobe epat # Sparq Protocol
modprobe pd # Sparq Driver

dmesg | grep paride
# Look for: "paride: epat registered as protocol 0"

# modprobe pd drive0=0x378,1 drive1=0x3bc,1 # Example syntax
# To support such a wide range of devices PARIDE, the parallel port IDE subsystem, is actually structured in three parts.
# There is a base paride module which provides a registry and some common methods for accessing the parallel ports. 
# The second component is a set of high-level drivers for each of the different type of supported device:
# pd IDE disk
# pf ATAPI disk
# pt ATAPI tape
# pg ATAPI generic devices

# The pg driver exists mainly to support parallel port ATAPI CD-R and CD-RW devices. 

# Run the commands below from a script 
# ================================================== ==================
echo "Running commandsmou..."
test `whoami` = 'root' || echo "You must be root to execute the commands."
cdrecord -scanbus > /dev/null
if ! (pidof kerneld || test -f "/proc/sys/kernel/modprobe"); then
echo "Neither kerneld nor kmod are running to automatically load modules".
report_no_autoload() {
echo "Ensure the module $1 is loaded automatically next time."
if test ! -f "/proc/scsi/scsi"; then
report_no_autoload scsi_mod && modprobe scsi_mod
if ! grep "^........ sg_" /proc/ksyms > /dev/null; then
report_no_autoload sg && modprobe sg
if ! grep "^........ sr_" /proc/ksyms > /dev/null; then
report_no_autoload sr_mod && modprobe sr_mod
if ! grep "^........ loop_" /proc/ksyms > /dev/null; then
report_no_autoload loop && insmod loop
if ! grep iso9660 /proc/filesystems > /dev/null; then
report_no_autoload iso9660 && modprobe iso9660
echo "The following is only needed for IDE/ATAPI CD-writers."
if ! grep ide-scsi /proc/ide/drivers > /dev/null; then
report_no_autoload ide-scsi && modprobe ide-scsi
# ================================================== ==============

# Now check if it is recognized:
# cdrecord -scanbus

# Mount to an appropriate location after placing a CD in the drive
mkdir /media/Sparq
mount -t vfat /dev/pda1 /media/Sparq
ls -al /media/Sparq # Works !
Save it under a name you like. I personally chose the name "Paride" (which is the name of the parallel port IDE subsystem)

Next, you need to make the file executable. Open up a terminal and type (or copy + paste) the following:

chmod +x paride
Now, you can run the script by typing in the following in a terminal

sudo ./paride
and you should see the directory of your Syquest drive!

*Note: you only need to run the script once per session. You can alternately mount and unmount the drive my typing the following:

sudo mount /dev/pda1
sudo umount /dev/pda1

If you see something in my Howto that could use improvement, please share!

Good luck, and have fun with your Syquest drive!
