I connected a CD-ROM to my pc532 (TOSHIBA XM-3501TA) and it seems to
be picked up at boot time (see boot messages below).

Yet, when I try to mount it I always get a failure:

[root@e1]# mount -t cd9660 -r /dev/cd0a /cd
mount_cd9660: /dev/cd0a on /cd: Operation not supported by device


What device should I use for this mount? /dev has:
brw-r-----  1 root  operator   4, 0 Dec 25 20:11 cd0a
brw-r-----  1 root  operator   4, 2 Dec 25 20:11 cd0c
crw-r-----  1 root  operator  12, 0 Dec 25 20:11 rcd0a
crw-r-----  1 root  operator  12, 2 Dec 25 20:11 rcd0c

Is there some config file I should update to allow using the CD-ROM?
I had no such problems using the tape unit (st0).

Finally, I noticed that I also have a Toshiba XM-3401TA which the
doco says is known to work, but I got the same failure. I should
say that this drive works just fine on NetBSD 1.6/pmax.
