The resource to read turned out to be:
/usr/src/linux-xxx/Documentation/sound (hope you installed the kernel source code, so you have the Documentation). The file to edit is /etc/modules.conf. The critical line in this file (after manual edition) is:
options sb esstype=1688 io=0x220 irq=5 dma=0 dma16=5 mpu_io=0x330
The change that I had to make was to insert the "esstype=" option. After modification, the best to test your setup is to cold reboot (power down, and then recycle the power).
4.4.2 How do I setup my printer?
From the GUI login screen, logon as root. If X-windows is not running, start an X-windows session by typing (as root):
startx
Read here [p ??] if your X-windows is not set up properly yet.
Start an X-terminal (perhaps by pressing the proper button) and type in it:
printtool &
This program does a complete printer setup, you just have to fill up the information about your type of printer and where it is hooked up.
Specifying the proper printer port is the most important part. If you don’t know which one is yours try:
on RedHat 5.2: lp1 (this is the first parallel port on RH5.2 ) or lp2 (this is the second parallel port on RH5.2) or lp3 (this is the third parallel port on RH5.2); on RedHat 6.0 (or later): lp0
(this is the first parallel port on RH6.x) or lp1 (this is the second parallel port on RH6.x) or lp2
(this is the third parallel port on RH6.x). After upgrading from RH5.2 to 6.0, the printing stopped working because the name of the parallel ports changed. I had to re-run the printool and adjust the port. The numbering of ports changed to bring it in line with numbering of other devices, 108
which always starts from 0.
Try printing an ASCII test-page straight to the port. Only when this works set up the bells and whistles.
If you are setting up a remote printer, make sure that your machine has the permission to use the remote printer. The permissions are set in the file /etc/hosts.lpd (more secure) or
/etc/hosts.equiv (less secure) on the machine to which the printer is attached. These files simply list the names of the remote computers that can use a local printer, one computer name per line. Mine looks like this:
hacker
mars
The file /etc/hosts.lpd did not exist on my system, so I created it.
For quick information about the printers on your machine, you may want to view the file
/etc/printcap :
cd /etc/
cat printcap
Here is the meaning of some codes that I see in my /etc/printcap:
109
:
Field separator (separates the entries in the file).
\
(at the end of line) Continuation on the next line.
Name of the printer. "lp" is the name of the default printer on your
machine. Subsequent printers are often, by default, given the the
lp
names lp0 or lp1, ... (or whatever you like) but this should not be
confused with the name of the devices (parallel ports) to which they
are connected.
sd=/var/spool/lpd/lp
My spool directory (sd).
mx#0
Maximum size of print jobs (mx) in blocks. "0" means no limit.
I want headers to be suppressed (sh). Header is the page with your
sh
name that prints before your printing job (waste of paper if you
print at home).
Name of the remote machine (rm), which on my system is called
rm=mars
"mars (my printer is connected to a different computer).
Name of the remote printer (rp), which is the name of the printer on
rp=lp
the remote machine ("lp" on "mars" on my home network)
or
or
the name of the device on the local machine. "/dev/lp0" is the first
lp=/dev/lp0
parallel port on RH6.x (it used to be /dev/lp1 on RH5.2, the
numbering of parallel ports changed).
Input filter (if). Your printing job will be formatted by this "filter"
if=/var/spool/lpd/lp/filter before it is sent to the printer.
Suppress the form feed (sf) that is normally sent when printing is
sf
completed (use it if your printer keeps printing an empty page at the
end of each jobs).
The printer is controlled using the command lpc (as root). Type "?" to see the options. This program is notorious for its peculiarities, so don’t get discouraged easily. The printer queue can be viewed with lpq and cleaned up with lprm , both of which work for a user (not only root).
