namely uuidgen(1), uuidgen(2) and uuid(3), the following division
has been choosen:
uuidgen(1) A description of the command line utility,
and other user oriented UUID information.
uuidgen(2) A mostly technical description of UUIDs.
uuid(3) A description of the functions and other
programmer oriented UUID information.
According to the division: add more technical contents.

always to the first 16 sectors of the disk. The firmware reads the boot
code from a partition, defaulting to 'a' if none is specified, which only
corresponds to the first 16 sectors of the disk if 'a' is first. Solaris
often makes the swap partition first, instead of the root partition, and
users expect to be able to do the same with freebsd as well. This also
allows one to temporarily boot from another partition if the boot block
on the root partition gets scrambled somehow.
o Remove all code guarded by !defined(__ia64__). This file is
specifically written for ia64,
o Handle the case when read_block() or write_block() fails. We
don't want sysinstall(8) to signal a thumbs-up on error,
o Set the starting (cyl,hd,sect) triple to 0xFFFFFF when either
bios_hd or bios_sect is zero or the LBA us not representable
with the triple. In that case automaticly initialize the
ending triple with 0xFFFFFF as well,
o Reindent Write_Int32() as it was different than the rest of
the file,
o Remove some unused variables that appeared to be used but
were effectively useless.
o Plug a memory leak: The second timne we read the MBR, we write
out a modified block, but didn't free the memory after writing.
o Replace d1->sector_size with 512 when we read/write the MBR.
We ignore the sector size in cases we shouldn't but adhered to
it in cases it would be wrong if the sector_size wasn't 512.
This file should eventually be rewritten to write out a GPT. For
now, a MBR will do...
<sys/gpt.h>. This avoids having to include both <sys/uuid.h> and
<uuid.h>, which is considered by your friendly committer to be
aestheticly displeasing (= ballyhoo barf barf :-)
gpt(8) have to include both <sys/uuid.h> and <uuid.h> only
because they include <sys/gpt.h> before <uuid.h>.
o Drop the triple bang in the unicode comment in favor of
adding '-16' to make it explicit that the unicode characters
are 16-bit. The fact that we use short as the type of the
array does give it away; but only to the careful reader.
path, instead of an internal i386 specific one. Don't try to interpret
a disklabel in ofw_disk.c, open the partition's device node directly and
let the firmware do it. This fixes booting from a partition other than 'a'
on sparc64, which is needed to support more installation methods.
No objection: ppc
Registry (LACNIC) with the -l option and support for recursive IP

byte operations, the surrounding 3 bytes are also affected by the
read-modify-write that has to occur.
we created for the boot floppy, or 2) construct an EFI partition
by copying bits from /boot. The first approach creates a bootable
CD image that loads a memory disk and starts sysinstall, the second
approach creates a generic bootable CD.
to be static for 5.0. I may remove this for 5.1 or 5.2. No more
binaries or libarires will be generated with __sF starting as of
yesterday. Originally the plan had been to eliminate this for 5.0,
but we didn't get the __std{in,out,err}p changes merged into -stable
until yesterday (rather than in September 2001 like it should have
been). Given that didn't happen on time, we can't do the other part
of the scheme now.

indirectly through vm_page_protect(). The one remaining page flag that
is updated by vm_page_protect() is already being updated by our various
pmap implementations.
Note: A later commit will similarly change the VM_PROT_READ case and
eliminate vm_page_protect().
1) Missing include.
2) Constness.
3) ANSIfication.
4) Avoid some shadowing.
5) Add/clarify some error messages.
6) Some int functions were using return without a value.
7) Mark some parameters as unused.
8) Cast a value we know is non-negative to a size_t before comparing.

If hw.hasbrokenint12="1" in loader environment, kernel never use BIOS
INT 12 call to determine base memory size.
Otherwise, kernel use INT 12 in old behaviour.
This should fix kernel panic problem caused by 1.544 changes.

Add in mpt && ahc now that they are modules. Unknown as to whether they
work yet or not.
