Ironically, such a change could make OS/2 bootable from a primary partition
that isn't the first, while you still couldn't boot DOS or WinXX from such
a setup on any but the first primary partition, given their requirement of
booting from C:.

But I still don't see why it should be done.  If DOS (i.e. Win95) could
boot from a logical drive, I wouldn't have any primary partitions (Win95 is
used only for games, needless to say).
