Yes, the default CD-ROM is always placed as secondary/master.

If you use -device ide-cd the implicit CD-ROM should go away.  However,
-drive alone doesn't have that effect (probably for backwards
compatibility reasons, this predates me even though by only a few months).

Alternatively, you can use -nodefaults of course.

Thanks,
