Yes, you can do that. However, perhaps you can do something without the floppy. We have put QNX on one C: partition and DOS on another C: partition. Then we use the 'fdisk' utility (which fortunetly lives on both OS's) to select the partition to use for booting. Granted, I know nothing of XENIX, or why this works for that matter... -- -------------------------------------------------------------------------------- FROM: Timothy R.
