trying to run X on some Athlon systems where the BIOS does odd things
(mines an ASUS A7A266, but it seems to also help on other systems).
Here's a description of the problem and my fix:
The problem with the old MTRR code is that it only expects
to find documented values in the bytes of MTRR registers.
To convert the MTRR byte into a FreeBSD "Memory Range Type"
(mrt) it uses the byte value and looks it up in an array.
If the value is not in range then the mrt value ends up
containing random junk.
This isn't an immediate problem. The mrt value is only used
later when rewriting the MTRR registers. When we finally
go to write a value back again, the function i686_mtrrtype()
searches for the junk value and returns -1 when it fails
to find it. This is converted to a byte (0xff) and written
back to the register, causing a GPF as 0xff is an illegal
value for a MTRR byte.
To work around this problem I've added a new mrt flag
MDF_UNKNOWN. We set this when we read a MTRR byte which
we do not understand. If we try to convert a MDF_UNKNOWN
back into a MTRR value, then the new function, i686_mrt2mtrr,
just returns the old value of the MTRR byte. This leaves
the memory range type unchanged.
I have seen one side effect of the fix, which is that ACPI calls
after X has been run seem to hang my machine. As running X would
previously panic the machine, this is still an improvement ;-)
I'd like to MFC this before the 4.6 code freeze - please let me
know if it causes any problems.

present, this field specifies the media volume that the disc is
contained on. If the volume of a given packages is different than the
current volume of mediaDevice, then the user is prompted --
"This is disc #%d. Package %s is on disc #%d\n"
"Would you like to switch discs now?\n"
If the user selects yes, then DEVICE_SHUTDOWN is called and the user
is then prompted --
"Please remove disc #%d from you drive, and add disc #%d"
This works well for a carefully crafted INDEX file, but more work
needs to be done to sort dependencies on a given package based on the
volume that they reside on, to minimize the amount of disc flipping
required of the user.
This commit is a no-op for normal INDEX files and FreeBSD CDs. These
additional features are only used if the INDEX and cdrom.inf file have
multi-volume support.
print out the correct transport it failed on rather than always
spitting out 'udp', also call nc_sperror() to give a more verbose
error message detailing the problem.
files are owned by the caller of newsyslog (usually root:wheel) even if
alternative ownerships were specified in newsyslog.conf.
Note that this is part of a wider problem which is fully addressed in
OpenBSD. Anyone with the time and inclination to incorporate the full
fix for the wider problem will receive no complaints from me and should
feel free to walk all over this delta.

"confused" about it being unassigned. In fact, gcc was right. Fix the
real problem by setting that variable before break-ing out of a select
statement so gcc is happy, and then remove the unnecessary assignment.

input file and any temporary (filter) file are closed upon return, and
that is generally done at the end of the routine. This should make it
easier for a later update (not yet written) to implement a "resend_copies"

remote machines. Now they really are handled *exactly* the same as
input filters (if=) for remote queues, except that they are started
with a different set of parameters. This should fix a few subtle
bugs in output-filter processing on such queues. It is a pretty
significant re-arranging of sendfile(), moving some of it to a new
execfilter() routine.

This patch explains -F for usershow and groupshow. Because "groupmod

command line args.

This is a WIP for 5.0 DP #1, so it is still rough around the edges and
does not GC the old XFree86 3.3.6 handling stuff that should be GC'ed.

The above command line will fail on -CURRENT or -STABLE, and
therefore, so will sysinstall if you try to install additional
packages through the network (FTP) from a multiuser system. Because
of the different environment during installation (wrt the playpen),
this bug does not manifest itself during initial installs, and users
may install packages from the network just fine at that time.
This bug was fixed in OpenBSD 4 years ago.

change (hopefully) shouldn't change anything.
I'll MFC to 4-stable later.
