a global, a couple of parameters, and opening up possibility of
traversing much longer EBR lists without blowing the stack.
Make seach algorithm the same as used in kern/subr_disk.c by checking
all primary partitions in the MBR/EBR before moving to next EBR. This
makes it more likely that everybody finds the same OpenBSD partition.
Largely from a diff posted to tech@ by ucsavl.

512-byte sectors) as some BIOSen get confused when we ask for sectors
higher up.
Uss u_int throughout the boot code to calculate sector addresses,
since 32 bits is enough to do 28 ^ 1 - 1 arithmetic. Add checks
for wraparound.
I can now install and boot from the 7th extended partition below
128GB.
Much feedback & guidance from deraadt@. Also from weingart@ on
BIOS io.

do 32-bit block spanning. If later on we get some that can/should do
64-bit, that can be done now using daddr64_t (but of course, we are taking
this step to finalize the daddr_t 64-bit conversion).

of the next EBR is relative to the start of the extended partition
described in the first MBR, not relative to the EBR specifying the
offset in its extended partition entry.
Clean up installboot -v output. Use daddr64_t for all sector numbers.
Not a complete fix, but better than what we had. More tweaks to
come.
Inspired by a diff and cluebat from uscav on tech@ a few weeks
ago.

softraid volumes. If installboot is run on a softraid volume, a fake
single inode FFS filesystem is constructed to contain boot(8). This is
then installed onto the softraid volume via the BIOCINSTALLBOOT ioctl.
biosboot(8) is then patched and installed onto each disk that is a member
of the softraid volume.
Joint work with otto@ who came up with the concept of constructing a fake
FFS filesystem and wrote the code to do so.
No objection from miod@

phessler for finding a small man page niggle. Bumped
version strings to a nice round fraction, and make them
the same across the board. Easier to identify boot

Not sure what's more surprising: how long it took for NetBSD to
catch up to the rest of the BSDs (including UCB), or the amount of
code that NetBSD has claimed for itself without attributing to the
actual authors.

grub in a few scenarios where grub doesn't report the CHS correctly
but the LBA. and we don't need CHS if there is LBA.

simple, it is just another mbr at the partition offset (well, the
standard "EBR" is a linked list with a few limitations, but this diff
works with both variants).

rather than relying on calls into the bios to work.
this is a result of me getting pissed off with solaris and linux
being able to cope the serial bios redirection on dracs, iloms, and
ilos. trying to do the same thing with openbsds boot loader caused
weird behaviour like machine hangs or no visible output. talking
to the serial chips directly is more reliable.

hacks in the boot loader in the future. This should have no

of '<' since read() can't return more than 'sizeof Y'. Not perfect

directive can select between MI and MD versions of these files. At
the same time, adjust the boot programs to pick exactly what they need,
instead of the 7 or 8 mechanisms previously used.
There will be some fallout from this, but testing it all by myself is a
ridiculously slow process; it will be finished in-tree.
Various developers were very nice and avoided making fun of me when I
was gibbering in the corner..

We don't want to pass the PXE MAC address to the kernel when booting
from a local disk, since the MAC address causes the kernel to look for
root on NFS. Do this by remembering (not adding to boot arguments) the
MAC address when opening the PXE device, and clearing this if we happen
to load a file off a non-network disk.
