* Theory:  boot block brings up a menu
* select an item and it loads that partition's boot block, O/S starts
boot sequence
* OS-BS 1.35, 2.0beta8, or booteasy 1.4 all work similarly.
* install or deinstall under DOS.
* ALWAYS start with bootable DOS floppy, copy the boot selector there

* Alternative: use pfdisk.exe under DOS to set NetBSD as the active
partition, boot DOS floppy to set DOS active if you need it.
