pc532 stand/boot
Phil Budne <phil@ultimate.com> 5/19/1994

Based on hp300 stand/pboot.c, uses libso
	(lacks the fun "spinner" that the i386 boot program displays)

May be debugged under usermode (using "testboot" image)

Passes howto, bootdev, & symbols to booted program;
	r3/ magic value 0xc1e86394 (3253232532)
	r4/ end of symbols
	r5/ physical load address (typ 0x2000)
	r6/ bootdev
	r7/ howto (flags: RB_{ASKNAME,KDB,SINGLE,HALT})

All files have Berzerkley style copyrights, except libso files from
Jordan Hubbard's "libso" (which in turn come from Bruce Culbertson's
ROM monitor); scsi_hi.c scsi_lo.c so.h

TODO:

check if kernel will overlap boot program!
pick up initial how and boot dev
