Disabling npx0 works right now.
Don't reference `npxdriver' if npx0 is not configured. Not configuring
npx0 doesn't quite work yet.
Don't clear potential non-npx pcb flags in setregs().
bell type on boot. Slightly annoying when your system doesn't have a speaker.
This adds a `keybell' frob for setting it. Closes PR#2519

character of the argument being processed isn't '\0'.
This fixes problem with backgammon exiting abnormally when you answer 'y' to
the question it asks if you need instruction for the game.
2.2 cnadidate, maybe?
should be nearly impossible to overflow the QOUTFIFO (worst case 9 command
have to complete with at least 6 of them requiring paging on an aic7850),
so don't take the additional PIO hit to guard against this condition. If we
don't see our interrupt in time, the system has bigger problems elsewhere.
If this ever does happen, the timeout handler will notice and retry the
command.
Remove the ABORT_TAG sequencer interrupt handler. This condition can't happen
with the new SCB paging scheme.
Fix a few bugs noticed by Dan Eischen <deischen@iworks.InterWorks.org>
that could prevent ULTRA from being negotiated to drives above ID 7 and
also could allow an SCB to be passed to ahc_done twice during error recovery.
Fix a bug notice by Rory Bolt <rory@atBackup.com>. It turns out that a
sequencer reset will actually start the sequencer running regardless of the
state of the pause bit. This could lead to strange problems with loading
the sequencer.
Only enable reselections once the channel and SCSIRATE have been cleared.
Add a pause block around the test busy code in the non-tagged case to simplify
error recovery in the corner case of aborting an SCB that just got started.
Simplify reselection processing by removing the call to initialize_scsiid.
Clear the scsiseq re/select control bits and setup for catching bogus
busfrees earlier in the re/select process.
Improve the automatic PIO code. It turns out that SPIORDY is not a reliable
hardware condition bit, so use REQINIT intstead. Don't rely on PHASEMIS
either since it can take too long to come true. Use a brute force comparison
instead.
Remove some unnecessary overhead in the command complete processing. It
should be nearly impossible to overflow the QOUTFIFO (worst case 9 command
have to complete with at least 6 of them requiring paging on an aic7850),
so don't take the additional PIO hit to guard against this condition. If we
don't see our interrupt in time, the system has bigger problems elsewhere.

not lazy-fault page table pages. Update the copyout support to take
that into account. This should fix some segfault problems on such
machines.
After a short test period, we'll move this into 2.2.

section was a good thing, since it made it possible to detect media problems
*before* the installation started, but it also caused various things to
be mounted BEFORE the chroot() call, which definitely messes things up.
Fix this by detecting the pre-chroot() case and mounting into a subdir.
