Support 32bit addresses >64k as valid on bios calls.
Move stack for dosboot and biosboot to >64 so stack doesn't hit data.
Use disk sector number passed by mbr code to select default partition
(the mbr code doesn't do this yet).
NB only biosboot and dosboot have been tested so far.
(changes approved by christos and fvdl)
is supported on later IBM PS/2 models; this is necessary to detect memory
over 64MB
thanks go to Pavel Cahyna for testing on his IBM PS/2 machine with 128MB
bump biosboot version to 2.15
to read sector 18, and fallback to 1.44MB drive geometry if that fails.
This allows to boot from 1.44MB floppy disk in 2.88MB drive.
Tested with 2.88MB drive in IBM PS/2 model 95 donated
by 'Yokotashi' <lhc at kanal ucw cz> and Pavel Cahyna

Bump biosboot version.
Fixes PR kern/3418 by Keith Moore.
Change okayed by Frank van den Linden.
* Add separate directories for the individual netboot ROMs and
always build them.
* Each bootloader Makefile explicitly specifies the start file
and link address it wishes to use.
* genprom becomes a proper host program.
* Make sure all generated files get cleaned up.
* Set BINDIR in Makefile.inc
* Add compressed image support to pxeboot.
* Make pxeboot use the default serial console speed (9600).
* recognize PS/2 L40 via biosmca() and biosmca_ps2model in gatea20.c, instead
of being a compile time option
* if the system is PS/2 with MCA bus, map DTYPE_ESDI disks to ed(4) for
COMPAT_OLDBOOT
The new code is conditional on SUPPORT_PS2 define, which is on by default
for biosboot-based bootblocks.
maps standard boot flags to corresponding RB_* values
use BOOT_FLAG() in port's MD code as appropriate
as discussed on tech-kern, add new boot flags -v, -q for booting
verbosely or quietly, and corresponding AB_VERBOSE/AB_QUIET
boot flags; also add FreeBSD-compatible bootverbose macro and
NetBSD-specific bootquiet macro
for hpcmips, use new bootverbose instead of it's own hpcmips_verbose
Tested on i386, and to limited extend (compile of affected files) also for
mvme68k, hp300, luna68k, sun3.
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.
from biosboot via the "consdev" command.
Move "Press return" printf() out of print_banner() so we can
print_banner() reasonably after switching devices.
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!

-make the boot timeout patchable
-optionally, call checkpasswd() before the boot menu can be accessed
(The latter 2 follow PR port-i386/8196 by Stephan Thesing.)
