I just love answering my own posts, but I figure other people might find this
useful. (BTW: What's up with the list, it took four days for my post to show
up)
If you've got an IDE cd-burner, you can enable ide-scsi support for it
without recompiling the kernel. This takes (as far as I can tell) two
steps...
add an append line to the linux section of /etc/lilo.conf so it looks like
this:
image=/boot/vmlinuz-2.2.14-5.0
label=linux
read-only
root=/dev/hda1
append="hdd=ide-scsi"
In my case, /dev/hdd is the IDE cd-burner. Now, run /sbin/lilo to make it
take effect. This should tell the ide-cd driver not to try stealing that
device, so the ide-scsi driver can later use it.
Step two: Add the following lines to /etc/conf.modules
alias scsi_hostadaptor ide-scsi
options ide-cd ignore=hdd
Now, reboot.
For me, neither ide-scsi nor sg were automatically loaded. There's probably a
way to make this happen by adding more lines to /etc/conf.modules, but I really
don't care. It takes three seconds to load them by hand. (modprobe ide-scsi
sg). When I do load them, I get the following kernel messages:
scsi0 : SCSI host adapter emulation for IDE ATAPI devices
scsi : 1 host.
Vendor: HP Model: CD-Writer+ 7200 Rev: 2.02
Type: CD-ROM ANSI SCSI revision: 02
Detected scsi CD-ROM sr0 at scsi0, channel 0, id 0, lun 0
sr0: scsi3-mmc drive: 2x/6x writer cd/rw xa/form2 cdda tray
Looks good to me.
