No the auto folder should not affect this.

PCDitto require that both C: and D: have valid IBM headers.  TOS doesn't
care if the IBM header is there or not.  The D: thing is curious but
its how I experienced it, and after disassembling the code, read it that
way.  Its a bug; now a feature!.

Also, for the C: to boot the IBMCOM and BIOS files must be the first in
the FAT and Directory.  If your resorter for the Auto folder or G+
muck arround with the order of these files you won't boot either.
