Enable efiboot on i386, for 32 bit bootblocks

Initial commit of native amd64 EFI boot loader.

Stop building boot ROM images for old PC NICs as discussed on tech-kern.

bootxx_cd9660 (cdboot), like bootxx_fat16 (fatboot), is not a traditional
libsa-based program. As such, build bootxx_cd9660 where its source lives.
This has been done by moving bootxx/bootxx_cd9660/Makefile to cdboot/Makefile
and adjusting the relative paths appropriately, so as to minimize binary change.

branches: 1.25.62; 1.25.70;
Descend into fatboot, regroup slightly

branches: 1.24.22;
No need to build pxeboot_com0 any more

branches: 1.23.16;
No longer build biosboot*.sym and installboot.

branches: 1.22.2;
Build my new i386 bootcode

Build mbr code here (instead of in sbin/fdisk/mbr)

Allow the serial console boot blocks to be built with a specific
console speed, and build some of the more common ones.

branches: 1.19.2;
Add host-OS tools for i386, which end up in the "installation/misc"
directory of the release tree.

* Rename the pxeboot binary from "pxeboot" to "pxeboot_ia32", since
there are other architectures (e.g. IA64) which also use PXE.
* Get the console right in pxeboot, from Andreas Gustafsson.
* Add a "com0" version of pxeboot, to address the same issue that
biosboot_com0 addresses.

Move the individual NIC ROM Makefiles into a subdirectories of
netboot. Requested by Christos.

Cleanup of i386 bootloader building:
* 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).

Add a PXE boot loader. PXE interface code is derived by code
written by Alfred Perlstein, Paul Saab, John Baldwin for FreeBSD.

Still needs some work, but this will load a kernel on a Soekris net4501.

Many thanks to Frank van der Linden and his simulator wizardry for
helping me debug the low-level startup code.

Nuke biosboot_ps2

add special bootblocks for IBM PS/2 - those machines need different gate A20
addressing

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!

Build biosboot_com0 too.

branches: 1.10.8;
Turn off biosboot_ser until makefile issues get worked out..

Also build serial bootblocks by default, installing into
/usr/mdec/biosboot_ser.sym
Change Makefile.booters to not assume `version' file is in source directory.

Ressurect (not quite, since this is in fact the new boot code Makefile
now).

All these files are ancient and haven't been used in years -- the
current boot blocks are in boot/; we need the thing cleaned out so we
can put the new libsa based boot stuff in its place.

LOCORE -> _LOCORE

new RCS ID format.

Add RCS indentifiers.

add rcsids to everything and clean up headers

after 0.2.2 "stable" patches applied
