I'll try.
It means:  don't use the ide-scsi driver.  Support for it is
lagging (not well-maintained) because it's really not needed for
burning CDs.  Just use the ide-cd driver (module) and
specify the CD burner device as /dev/hdX.

Example with cdrecord:
deprecated:
cdrecord -dev=1,0,0 -data backup.iso
modern :)
cdrecord -dev=/dev/hdc -data backup.iso

Do you know how to _not_ use ide-scsi?  Don't load the module
if you have it built as a module, or don't build it into the
kernel boot image.  Mostly don't try to open /dev/sdX, just use
/dev/hdX instead.

Hope you feel better soon.
