Ok, that makes sense. I've never used ide-scsi.
I've now tried this with two different atapi cdroms, one of which is a
brand new burner, the other a cd/dvd drive, and neither are bottom of
the barrel junk. In both cases the drives get mapped to (11,0), and
cannot be mounted/played. I haven't tried a vanilla cdrom yet.
I wouldn't be surprised if this has to do with Mandrake's distribution as
a few others are reporting the same problem, but unless I want to
rebuild the machine (again...), I have to live with it.
Is it possible for me to convince devfs to assign the cdrom to (the devfs
equivalent of) /dev/hdc, at least until Mandrake 8.2? I don't really
understand why the ide cdroms should be run through the scsi driver
anyway, and since they don't work there, I'd just as soon avoid it.
The ide drivers are in the kernel, not modules, and I've already tried
append " hdc=cdrom"
in lilo to no avail.
Cheers,
Gary
