I presume you are putting the "hdc=ide-scsi" as a kernel param.
I do similarly, EXCEPT the CDwriter is on its own IDE bus.
I suspect that the hdc=ide-scsi thing will apply to both master and slave
on an IDE channel - whether that is intended/mandated I can't say.
If you move the zip to hdb all should be well, or buy an IDE PiC and get
more channels if you have run out.
