I have begun to do it too, with an ide cd-writer.

I don't know if it is valid with other kernel but with the 2.2.14. I use on
my big linux, assuming my writer is on hdc, I have to pass the kernel the
parameter
hdc=ide-scci, via lilo or loadlin. With that parameter the kernel don't
register hdc as an ide device, but instead as a scsi one.
Maybe this can be automated in mulinux, if lilo is here.
then I insmod ide-scsi.
To mount it I use mount /dev/scd0, as it is considered as a SCSI cdrom.
When used as a cd-writer, it has to be accessed via the generic scsi
interface, it is /dev/sg0 if accessed through the /dev/ interface.
In cdrecord, it seems that the prefered way to address a scsi device, is a
triplet like 0,0,0 for the scsi bus, the place on the bus and anohter arg
I don't remember.
cdrecord -scanbus gives you the topography of your bus. I have no scsi
device, only that scsi emulated ide burner, so it is on 0,0,0, but maybe it
isn't the case for your device ?
Pat
note that I also tried to use it in a box that accept ide device and plugs
into the parallel port, but failed to have it work that way under linux. Now
I have a hard disk in that box, and it works well. Does someone know wether
the parport suite modules exist in the 2.0.36 ? Maybe I could do .cnf and
.fun for external parallel port devices if someone think it is worth. I have
some knowing in that area, and I even did some script that brutally probe for
the hardware in tempting to insmod the modules to find which one is the good
one.
