dvd + cdrw + modules = problems
I have been trying to set things up with a DVD on hdc and
a CD-burner on hdd using modules, but without success.
I am using Debian/unstable with kernel 2.4.20 configured in
the same way as the Debian package kernel-image-2.4.20-686,
that is with a highly modular kernel. I am willing to
believe that things might work more easily if I compiled
in support for the DVD and CD-burners, but for the present
I am stubborn and would like to make it work with modules.
Although the DVD-drive works as expected, the CD-burner
does not work properly. For example,
conrad@viszla:~$ su

cdrecord: No such file or directory. Cannot open '/dev/pg*'. Cannot open SCSI driver.
cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you are root.
cdrecord: For possible transport specifiers try 'cdrecord dev=help'.
cdrecord: Also make sure that you have loaded the sg driver and the driver for
cdrecord: SCSI hardware, eg. ide-scsi if you run IDE/ATAPI drives over
cdrecord: ide-scsi emulation. Read /usr/share/doc/cdrecord/README.ATAPI.setup!
