Learn the syntax of modules.conf (see "man modprobe") and write an
"include" file. Then save it as /etc/modutils/whatever and call
update-modules. Alternatively, use modconf as described in my
mini-Howto for Potato (cdrecord-1.10a02, README.ATAPI, latest section):
From: Eduard Bloch <email@example.com>
Linux: Kernel 2.2.15 (Debian package kernel-image-2.2.15)
Distribution: Debian Potato (deep freeze), i386
Devices: one CDRW-Writer, one CDROM-drive, both ATAPI
1. Become root, try "grep hd.: /var/log/kern.log" to find out where your
ATAPI-devices are connected to (hd?-names).
2. Edit your boot configuration file, eg. /etc/lilo.conf if you use
lilo or the batch-file if you boot via loadlin.
3. Find a line where you can append additional kernel parameters, eg.
"append=" in lilo.conf or the loadlin-line in the batch file.
4. Append sth. like this: "hdb=ide-scsi hdc=ide-scsi max_scsi_luns=1"
The hdX-parameters defines devices that should be mapped to SCSI
latter. You may do it with non-writers too, since the emulation layer
is almost complete, or let them out so the devices will use their
5. Save the file, reinstall the bootloader (ie. running "/sbin/lilo")
6. Call "modconf", load "sg" and "ide-scsi" from the SCSI-section
7. Reboot Debian, watch while booting, you should see a line like this
"Detected scsi CD-ROM sr0 at scsi0, channel 0, id 0, lun 0".
Your old ATAPI devices virtually don't exist any longer, use ther
SCSI equivalents instead.
8. Become root, setup devices:
MAKEDEV sg scd
ln -s scd0 cdrom # NOTE: or cdrw, first check which drive is here
ln -s scd1 cdrw # NOTE: see above, maybe cdrom
Check the new SCSI settings:
Setup cdrecord's environment - edit /etc/default/cdrecord:
cdrw=1,0,0 4 8m
cdrom=1,2,0 0 0m
Input the right values, the fields are described in the manpage
of cdrecord. Alternatively, you may use this values as
cdrecord-parameter or take a frontend with an own configuration
scheme, then you don't need to modify /etc/default/cdrecord.
9. It's done! Insert a CD and try "cdrecord -v -toc"
