Features:
o Boot both a.out and ELF kernels
You can install an ELF kernel now, but boot an aout kernel
if necessary, without changing the bootblocks.
o Boot from any slice
Supports multiple bootable FreeBSD slices on the same disk.
This is all-new code (not derived from biosboot) and was really
written as a test case for BTX, the "boot extender" developed to
support the forthcoming 3-stage boot code (/sys/boot/*).
The code is made available mostly to encourage testing of a BTX-hosted
application while the new loader code is still in preparation.
Most of the current boot1/boot2 (biosboot) functionality and syntax
is supported.
EDD (boot above cylinder 1023) support may be added later, if space
permits.
The code requires a fairly recent elf -current to compile, but
binaries are included.
