algorithm is used on aic7770 Rev E or higher chips to improve perfomance.
This required a hardware change but we don't know exactly what (most
likely some special register to do fast SCB indexing into host memory),
and we are not at all sure that there are more than 4 SCBs on these
chips. This probe will still classify the revision of the aic7xxx, but
we now default to 4 SCBs (at least until we know more of what was done).
This also fixes a bug in the timeout routine where we cleared a flag
too soon making it imposible to enter one section of the routine.

interrupts to zero to start with. This is the value we return in
most cases. The sense code then outbs the apropriate value to cause
sense retrieval. The return value was uninitialized before this
change (something that was an okay thing with the old sequencer code,
but not with the semantics of the new).
This problem caused us to always retrieve sense upon recieving a non
zero status byte. This is exactly what was happening for the "target
busy" status returned by exabyte tape drives when they rewind or
power on with a tape installed. The request sense proved fatal.
This should fix the tape problems.
but it outlines what I'm GOING to do to this file.
It's sort of an unignorable notification of coming changes..
This is a bit rude I understand.. but I can't afford to haqve the
diskslice code drifting off too much further from a workable system
and I think I need to jump in now to make it obvious what has to be done
before it's too late.
appologies to bruce in advance.
bin/stty. Define alias CCAR_OFLOW for MDMBUF.
Declare speeds as having type speed_t instead of long. speed_t is
long, which is wrong (POSIX specifies it to be unsigned integral),
but fixing it might introduce more serious bugs.
package: check installation, build package, create links,
touch cookie
repackage: ditto but don't check cookie
package-noinstall: just build package from installed stuff, no cookies
involved at all
package-links create the symbolic links only
delete-package: delete package and symbolic links
delete-package-links: delete links only
These should make the management of the spaghetti of package links
a little friendlier. :)
Add mbr and bteasy17 to tst01
read partitions from kernel instead of disk.
Still problems with writing labels, discussing with Bruce.
Extended slices doesn't get written yet.
FreeBSD), add mach-4 target to MAKEDEV; it creates various compatability
devices for Mach4.

user-level part has already been commited.)
Note that i've lost the "official" code for this; it went into the
system after 1.1.5.1. The commited code is my own version, but it has
proven to work for me for more than a year now.
o Make the framework generally more robust.
o Figured out how to nest the menu descriptions - no more grotty initialization
of menus.
o Fix bug with helpline and helpfile not being reset.
o Add stubs for the media selection code.
Coming next: Fdisk and disklabel screens using Phk's new libdisk stuff.
- If you take the wheel entry out of /etc/group and turn on NIS,
the '+:*::' line is incorrectly flagged as the entry for wheel (the
empty gid section is translated to 0), hence getgrgid() returns '+'
as the name of the group instead of 'wheel.'
- Using just '+:' as the 'turn on NIS' switch in /etc/group makes
getgrgid() dump core because of a null pointer dereference. (Last
time I was in here, I foolishly assumed that fixing the core dump
problems with getgrnam() and getgrent() would fix getgrgid() too.
Silly me.)
and `rtsflow' are the components of `crtscts'. `dtrflow' and `dsrflow' are
new and not yet supported. `dtrflow' may be useful for Cyclades serial
careds, which have h/w support for it and no h/w support for `rtsflow'.
print.c:
Report NTTYDISC in case the line is in this obsolescent state.
if an invalid ioctl is done on /dev/klog. logioctl() needs to return
an errno instead of -1 on a failed ioctl.

Made an All_FreeBSD() function.
Added a cmd-line interface (lowest rank) to the tst01 program.
The tst01 program is harmless (worst it can do is coredump), but it
is instructive to run, you can see what the slice-code things of your
disk...
