Maybe it did find plan9.ini -- the bootdisk.img on the CD is set up
to prompt you for those parameters.

Assuming it did find plan9.ini, add a line

	bootfile=sdC0!dos!9pcflop.gz

into the plan9.ini.  Then it will figure out that
the boot floppy is on sdC0!dos, and will use the
vgadb there, if found.
