I'm running FreeBSD-2.1.0-RELEASE and have a Matsushita/Panasonic CD-ROM
drive (proprietary interface) attached to the controller port of a
Soundblaster 16 VE card.  The interface and drive should be compatible, and in
fact the boot-time probe finds both:

[dmesg extract:]
matcd - Matsushita (Panasonic) CD-ROM Driver by FDIV, Version  1(26) 18-Oct-95
matcdc0 at 0x230-0x233 on isa
matcdc0 Host interface type 0
matcd0: [CR-5630.75]  

According to its label this drive is in fact a "CR-563", not 5630, but I'd
assume this ID is close enough...

Anyway, I haven't been able to access the thing at all, either for reading
data CD-ROMs or playing audio discs.  Any command attempting to use it
returns a "device not configured" error, and in the system log I get:
 matcd0: Could not read the disc size

(regardless of type of access being attempted).  The drive-activity LED never
even lights up!  I'm not 100% certain that this CD-ROM even works... it
hasn't been tested yet under DOS/Windoze since I can't locate any drivers
for that environment.  It's jumpered for ID#0 (from a choice block of 0,1,2,3).

My /dev nodes are:
brw-r-----  1 root  operator   17,   0 May 20 08:51 /dev/matcd0a
brw-r-----  1 root  operator   17,   2 May 20 08:51 /dev/matcd0c
brw-r-----  1 root  operator   17, 128 May 20 08:51 /dev/matcd0la
brw-r-----  1 root  operator   17, 130 May 20 08:51 /dev/matcd0lc


(what are the ones containing "l" for?  well, they don't work either in any
case...)

I'm basically at a loss here, but would like to get this drive working
eventually-- would greatly appreciate any help! :-)  If you've got a beast of
this type up & running I'd like to hear from you...

thanks in advance,
