I installed a Nakamichi 7 disk CD-ROM changer last night to my
FreeBSD-2.1.0-RELEASE system. I had to add the following two blocks to
scsiconf.c. Maybe some kind soul would commit them so that any future
owners of this device won't have to figure it out..
/* Nakamichi 7 disk CD-ROM changer */
{
T_READONLY, T_REMOV, "NRC", "MBR-7" ,"*",
"cd", SC_MORE_LUS
},
/* Nakamichi 7 disk CD-ROM changer */
{
T_READONLY, T_REMOV, "NRC", "MBR-7"
,"any", "cd", SC_MORE_LUS
},
Now for my questions...
1. Why wasn't this the other way around? I mean wouldn't it make more sense
to keep a list of devices that misbehaved.
2. Do I need to change anything else in the kernel? I mean like a timeout
value or something. Here's what is happening: I run a script after
rc.local to probe for any available CD-ROM's in known CD-ROM devices
and mount them. I booted with two CD-ROM's in the changer (at cd0 and
cd1) and one in mcd0. The script should have found them all, but only
mounted the one's at cd0 and mcd0. I ran the script again, and it
found the one at cd1. My thought was that maybe it took too long to
change trays. Any suggestions.
3. How can I read the CD-ROM's label? When mounted under DOS, all drives
(including CD-ROM's) have labels. For instance, the FreeBSD-2.1.0
beta CD when mounted under dos says something like "FREEBSD-2.1.0".
How can I get this info?
