In general, a PC clone has no way to boot from a second drive.  The BIOS
ROM does not support this.  The MSDOS boot code, I think, does not support
this and I know that the wd*.c boot code in 386bsd does not support this.

I have a system with a 124Mb drive 0 and a 42Mb drive 1.  I worked around
this problem by creating a 31.9Mb DOS partition and a 92Mb 386bsd partion
on drive 0.  Drive 1 is 100% 386bsd.  I put the man pages and emacs and
some other less often used stuff on the 42Mb drive because it is slower.
This partitioning is less convient than having it all in one piece but it
does allow me to switch back and forth without minor surgery.
