OK, firstly, is your CD-ROM an IDE device _or_ a Matsushita/Panasonic
proprietry device? The controller matcd0 is only for CD-ROM's with the
proprietry Mat/Pan interface (as used on SB cards) not for IDE devices
_made_ by Mat/Pan.
If it is IDE then you don't need ``matcd0'' in your config file. Also,
there is no such thing as ``device matcd0'' only ``controller matcd0''
(look in /usr/src/sys/i386/conf/LINT).
The following is from the handbook:
Proprietary CD-ROM support
The following drivers are for the so-called proprietary CD-ROM
drives.
These drives have their own controller card or might plug into a
sound
card such as the SoundBlaster 16. They are not IDE or SCSI.
Most older single-speed and double-speed CD-ROMs use these
interfaces,
while newer quad-speeds are likely to be IDE or SCSI.
device mcd0 at isa? port 0x300 bio irq 10 vector mcdintr
Mitsumi CD-ROM (LU002, LU005, FX001D).
device scd0 at isa? port 0x230 bio
Sony CD-ROM (CDU31, CDU33A).
controller matcd0 at isa? port ? bio
Matsushita/Panasonic CD-ROM (sold by Creative Labs for
SoundBlaster).

As it is the secondary slave, it is on wdc1 which the dmesg output shows
is not being detected, so if the controller is not detected any device
on it won't be either. We need to find out why not. It isn't disabled in
the BIOS is it? (if you've got Windows on the machine and the CD works
there then it must be enabled).
The second thing to ask is why is it the slave on the secondary IDE
channel?. Have you got another HD as the master on the second channel?.
If not then that could cause problems, try making the CD the master on
the second channel.
Is your IDE on the motherboard or an add on card? I ask this because my
first PC had the IDE on a card but with only one port. When I got a
CD-ROM I bought a card which had a (single) IDE port but configured as
the second channel (IRQ15, 0x170). This was common once when IDE
CD-ROM's first appeared. Anyway I could not get the CD working under
Windows or FreeBSD and eventually threw out both cards and bought one
with dual IDE ports. Turns out it had _exectly_ the same chipset as the
original single port card and that was the problem, the chipset
supported both channels and wouldn't let any other devices use the IRQ
and address even though it wasn't using them for anything. Could this be
your problem?.
See if you can figure why the kernel can't detect wcd1 (if your drive
really is IDE). Fix that and your CD should be found as wcd0 (master) of
wcd1 (slave).
Let me know how you get on.

Trust the computer industry to shorten Year 2000 to Y2K. It
was this thinking that caused the problem in the first place.
