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, -- Jordan.
