OK you can do it another way if your willing to load modules(you
originaly said "configure CD-RW...-there will be no modules to load").
I set CONFIG_BLK_DEV_IDECD=m along with the four scsi modules listed
above. This way i can access my CDROM/CD-RW as either ide(hdc) or scsi(scd0)
drive depending upon which modules i load. As long as you config IDECD as a
module you will not have to append="hdc=ide-scsi" to use scsi-emulation.
You need scsi-emulation to record, so you must load the scsi modules and
unload the ide module(if its loaded).But if you only want to use a CD-RW for
reading a cd then you can use either the ide(hdc) module or scsi(scd0)
modules.
Use 'modprobe' to load modules and 'rmmod' to unload. Then 'lsmod' to list
the current modules loaded.If you only have a CDROM and want to configure
for CD-RW you can just use ide-cd and when you get a CD-RW you will not have
to re-configure to start recording.
