Bowrite guarantees that buffers queued after a call to bowrite will
be written after the specified buffer (to a particular device).
Bowrite does this either by taking advantage of hardware ordering support
(e.g. tagged queueing on SCSI devices) or by resorting to a synchronous write.

Include only register specifications for those chip sets that apply to
a cpu that might boot this a particular kernel (ie. make the Saturn code

I just couldn't get the code to be as small as it should have gotten..
atill a LITTLE bigger than before as I need to allow the
default string to have options as well
1/ Makefile: the maximum size for boot2 is 7.5K not 7K,
so don't complain until it reaches THAT size..
newfs leaves 8K and boot 1 is 512k. leaving 7.5K becasue the disklabel
is considered to part of the boot2 file.
[512 boot1][512 disklabel][ 7K boot2 code ]
[boot1 file][ boot2 file ]
2/ Boot2.S: move the soring of the default name read from block 2 to AFTER
clearing the BSS.
3/ boot.c:
Move the parsing of the command line into the
place it's called for clarity.. alsoi comment it a bit and clean it
up a bit.. for some reason this seems ot have made it a little
larger, but I can't work out why.. maybe bruce might have ideas?
compensated for by shrinkage elsewhere..
the practical result of this is htat the default string can now contain args
e.g. if you change the default string to have -gd
then the machine will boot to the dgb debugger stub by default..
this is mostly useful with the nextboot utility..
as it now allows you to remotely force a machine to reboot into
the debugger.

way it attaches multiple PCI buses directly to the CPU, instead of having
them hanging off from PCI to PCI bridges. This code is a hack, and will
be obsoleted by the planned rework of the PCI code, which will change the
dealing with PCI to PCI bridges and other special devices significantly.
The patch also adds a kern_devconf entry for PCI bus 0 which is assumed
to be a child of cpu0. The new PCI code will make it possible to hand out
the kern_devconf structure to a pci device being attached, since this is
(regretably, IMHO) required by a few ISA devices.
Finally there are new PCI ids for some Intel chip set devices, which had
already been known to 2.1.5R, but did not make it into -current. This closes
"kern/1558: PCI probe seems to have lost a device in -current".
is non-null before trying to delete it in rt_setgate(), which then
allows removal of the special-case code from the RTM_ADD case.
This should fix the panics that joerg and Phil Karn have been seeing.
returned by the RTC, use the bootblock supplied value. Also, map the
'stolen by BIOS' memory in the same manner as the ISA-hole memory, since
it is really an extenstion of the BIOS. This is necessary for 32-bit
BIOS functions such as APM support on laptops, and the loss of memory
for non-necessary functions seems to be at most 4k.

Add definitions for the 802.3/Ethernet MIB. To implement this, simply
add a `struct ifmib_iso_8802_3' somewhere in your interface's softc,

with appropriate values. (I didn't want to create Yet Another Ethernet-

The only excuse this had for becoming misordered was that some drivers
were sorted on the driver name field, but the ffs versus mfs ordering
shows that this is not a consistent order.
The only case that I know of where simple sorting is wrong is for files

normally otherwise. Then the line with `profiling-routine' must appear
first to get the file compiled with ${PROFILE_C}.

The interface into the "VMIO" system has changed to be more consistant
and robust. Essentially, it is now no longer necessary to call vn_open
to get merged VM/Buffer cache operation, and exceptional conditions
such as merged operation of VBLK devices is simpler and more correct.
This code corrects a potentially large set of problems including the
problems with ktrace output and loaded systems, file create/deletes,

Most of the changes to NFS are cosmetic and name changes, eliminating
a layer of subroutine calls. The direct calls to vput/vrele have
been re-instituted for better cross platform compatibility.

half way through the range rather than possibly colliding with

remember that each element in the array is now only 1 ponter so this

also note a possible bug in debugging code in uipc_socket2.c (add XXX)
I've been meaning to do this for AGES as I keep having to patch those routines

any module that assigns resources to processes needs to know when
these events occur. there are existsing modules that should be modified
