Very Computer

Again, I may be way off base and there might just be some kernel config
option. I just posted first :)

A year ago when I first tried Linux I could not get it to recognize
the CD-ROM drive in my main system, because that drive is configured
and connected, via an add-on card, as the tertiary (third pair)
master. This week I returned to Linux with RedHat 4.1 and it *still*
will not see the CD-ROM drive (I run NT 4 on the same system and it
sees it fine). Is any progress being made, or am I overlooking some
configeration modification I should write in?

Linux supports up to 4 IDE interfaces for up to 8 devices. It
supports them for several years now. See /Documentation/ide.txt
in the Linux kernel source for more details.

    ide3=0x168,0x36e,10 /* ioports 0x168-0x16f,0x36e, irq 10 */

Normally the irq number need not be specified, as ide.c will probe for it
[..]

      append = "ide2=0x1e8"

   in /etc/lilo.conf, and re-run lilo; then the tertiary interface will
   be detected at boot-up. (Note that tertiary interface is ide2, primary
   and secondary ones being ide0 and ide1.) That if the second ioport
   is at the standard offset from the first (at 0x3ee for ide2); the IRQ
   will be autodetected. (Documented further on in ide.txt.)

Now, 2.0.x is the current ruler of the Linux roost, and it does support
the tertiary and quartenary IDE ports. Unfortunately, it does not
autoprobe them, so you have to tell the kernel that they are there,
or you need to modify the ide.c driver in the kernel source to detect
them automatically. Read /usr/src/linux/Documentation/ide.txt for the
boot arguments for the third and fourth IDE ports.

The corect syntax is "hde=cdrom".
You can also specify the port. Read the ide.txt file in
/usr/src/linux/Documentation. "ide2=0x1e8" "ide3=0x168"
All the kernel needs is a little poke to probe the interfaces.

Or, if you're particularly creative, you can add the autoprobe
sequence to the third and fourth IDE interfaces in ide.c
