- This is probably because Unix (and Xenix) requires that it be booted from
- an Active partition. The boot manager will start the boot sequence, but
- Unix will fail since it is not being booted from the active partition. When
- Unix boots it accesses device files to access the hard disk. One of the
- device files refers to the active partition, regardless of whether it is
- the boot partition or not. Since Unix refers to these device files during
- boot the boot operation will fail.
