This change courtesy of Charles Hannum <root@ihack.net>. This
...
addresses the problems seen by Jason Thorpe <thorpej@netbsd.org> and
Erik Berls <cyber@netbsd.org> necessitating rev 1.20 of
biosboot/main.c.
Move BOOTSEG from 0x100 to 0x1000.
Move heap from 0x10000 to 0x20000.
XXXXXXXX
This is a Kluge From Hell to allow boot blocks to grow a little larger
without diskbuf[] crossing a 64k boundary.

Addredd port-i386/9897, but differently. Since the effect of resetting
...
the video mode on machines with ancient or no video cards is not clear,
for safety's sake a I created a new biosboot variant, biosboot_resetvideo
that does the call.
Anyway, now I can boot my i-opener without hitting Tab. Thanks Andrew!

Unlike in an i386 a.out assembler, where in an .align n directive n is meant
...
to be the logarithm to base 2 of the alignment, in an ELF environment n is
the actual alignment boundary; thus, adjust the directives accordingly.
Albeit the wonderful i386 architecture doesn't mind the smaller alignment in
an obvious way, it is likely to have resulted in some performance penalty
during the a.out->ELF transition.
