It's based on the newest i386's one and has the advantage of:
- ELF binary support.
- UFS2 filesystem support.
- Many FreeBSD slices support on a disk.

of as hack that spans two other fields (adaptor (sic) and controller)
that are not used in any modern FreeBSD boot code.

pc98 boot2 is compiled with _KERNEL defined, and that makes non-static2007-04-06T20:50:24ZAlexander Kabaevkan@FreeBSD.org2007-04-06T20:50:24Zurn:sha1:7d80a3b49364287315f87a1b562ac25ab8dec646

declaration in this file. Declare variable as globally visible in
order to resolve the conflict.
Revert the last change. Masking only 2 MSBs of the virtual address2006-11-02T17:28:38ZRuslan Ermilovru@FreeBSD.org2006-11-02T17:28:38Zurn:sha1:593bbd21955c092921e03dbe52d261939267da4c
to get the physical address doesn't work for all values of KVA_PAGES,
while masking 8 MSBs works for all values of KVA_PAGES that are
multiple of 4 for non-PAE and 8 for PAE. (This leaves us limited
with 12MB for non-PAE kernels and 14MB for PAE kernels.)
To get things right, we'd need to subtract the KERNBASE from the
virtual address (but KERNBASE is not easy to figure out from here),
or have physical addresses set properly in the ELF headers.

are no longer limited to a virtual address space of 16 megabytes,
only mask high two bits of a virtual address. This allows to load
larger kernels (up to 1 gigabyte). Not masking addresses at all
was a bad idea on machines with less than >3G of memory -- kernels
are linked at 0xc0xxxxxx, and that would attempt to load a kernel
at above 3G. By masking only two highest bits we stay within the
safe limits while still allowing to boot larger kernels.
(This is a safer reimplmentation of sys/boot/i386/boot2/boot.2.c
rev. 1.71.)
