Fix one such THING in code to match comment.
Sort IO_GSC* into numeric order and update comments about the gaps.
Sort common SCSI addresses into alphabetical order.
Remove bogus comments about com ports having i/o size 4.
Uniformize whitespace.
Uniformize case in hex digits.
This file is very incomplete. In particular, it doesn't mention any
network cards. This doesn't matter much for the base addresses, but
it means that the comments about which addresses are free are mostly
bogus. The i/o sizes are unreliable because of split address ranges
for many devices (VGA, wd). The i/o sizes are incomplete. In
particular, there are no sizes for SCSI controllers. The bt driver
still returns a truth value instead of a size.
the National Semiconductor InfoMover PCMCIA cards also. In tests on a
NE4100 on Jordan's laptop here, the ze driver works fine with that
card.

the 802.3 frames generated by the DC21040 (which does automatic padding
of less-than-minimum frames) and the frames generated by the 'ed'
driver, I've found that there is indeed a bug in the size of "ETHER_MIN_LEN"
as reported by several people, John Hay being the most recent. The driver
was actually setting the length to 6+6+2+50 (64 bytes), which when adding
in the CRC (which is automatically appended to the frame and not included
in the length), the minimum frame is 4 bytes larger than it is supposed to
be. All of this is confirmed by tcpdump showing 50 bytes of data for
minimum frames from the 'ed' cards and 46 bytes from 'de' cards. This
analysis has also revealed that there is garbage in the un-filled in
portion at the end of the minimum frames from the 'ed' driver; I don't
plan to fix this.
A phone call from Manfred quickly pointed up the fact that I got the conflict
check backwards. NOW we implement the conflict checking correctly! Wheesh!
to access it. setdelayed() actually ORs the bits in `idelayed' into
`ipending' and clears `idelayed'.
Call setdelayed() every (normal) clock tick to convert delayed
interrupts into pending ones.
Drivers can set bits in `idelayed' at any time to schedule an interrupt
at the next clock tick. This is more efficient than calling timeout().
Currently only software interrupts can be scheduled.
It closed the wrong device (usually the B partition instead of the C
partition).
It closed a device without having opened it.
It didn't open a device often enough. This caused swap partitions on
slices other than the first slice looked at to be unavailable for swapping.
It didn't check the device number sufficiently.

This work is -not- complete, but it's in far better shape than it was, and
I may not touch it again for another few months.
The ``flags 1'' in the fdc line is now only needed for owners of an

to be `int' or smaller and some functions returned `int' instead
of `void'. The first bug was detected when console functions were
defined in a place central enough for type checking to actually
work and the second bug was introduced when the interface was
changed to match what the console functions in other drivers actually
return.
through the use of the config file flags as opposed to the option
"NSECS_MULTI". "NSECS_MULTI" has been removed from the driver.
The new capability allows boot-time modification of the config.
I made the changes I sent you before. In the interests of cleanliness, I made
modifications to /sys/i386/isa/tw.c to kill the warnings and make it compile
clean. While I was at it, I also made a bunch of internal functions static.

higher level scsi code.
Spls should never be conditionalized, so don't do so here.
Restructure the get_ccb routine so that we can't get into an infinite
loop if the ccbs are exhausted and we are are called with SCSI_NOSLEEP set.
Other driver maintainer's that based their ccb allocation routines on Julian's
code should look at these changes and implement them for their driver.

Previously, this worked right if both AUTO_EOI_1 and AUTO_EOI_2 are
defined, but not if AUTO_EOI_1 is defined and AUTO_EOI_2 is not defined.
The latter case should be the default. DUMMY_NOPS should be the default
too. Currently there are only two NOPs slowing down rtcin() (although
there are no delays in writertc()) and several FASTER_NOPs slowing down
interrupt handling in vector.s.
Fix stack offsets for the (previously) unused untested
FAST_INTR_HANDLER_USES_ES case.
This should NOT go into 2.0.5 /phk
Support disk slices. This involves mainly replacing inline code with
function calls. Support for ST506 drives is temporarily broken since
the `setgeom' arg to dsopen() is not implemented completely enough to
use. The `setgeom' arg will go away and ST506 drives will be supported
in another way. A large amount of dead code is left in wdopen() as a
reminder of the problems here.
Close the device in wdsize(). Open tracking was broken on all drives
with a swap device.
Remove support for soft write protection. There are no ioctls to set
it. It was used to disable writing to unlabelled disks, but we want
to support writing to foreign partitions on unlabeled disks.
Use generic dkbad routines to do about 2/3 of the work for supporting
bad144.
Improve disk statistics: estimate 4MB/sec instead of 8MB/sec for
the transfer rate (ISA max is 4MB/sec, old IDE max is 3.3MB/sec);
fix dk_xfer[] (it counted sectors, not transfers); keep the estimate
dk_seek[] = dk_xfer[] (was sectors, is now transfers); only count
words actually transferred (the count is still too high after a
failed write and after retries). Remove wdxfer[].
Fix indentation in wdattach(). Fix resulting botched printing of the
disk size for ST506 drives. Print the disk geometry less cryptically.
Dropping into the debugger when a break comes down the serial line is a
>MISFEATURE (1st class)< and has been put under it's own #ifdef. This
should be a magic sequence of chars instead.
For those where it was easy, drivers were also fixed to call
dev_attach() during probe rather than attach (in keeping with the
new design articulated in a mail message five months ago). For
a few that were really easy, correct state tracking was added as well.
The `fd' driver was fixed to correctly fill in the description.
The CPU identify code was fixed to attach a `cpu' device. The code
was also massively reordered to fill in cpu_model with somethingremotely
resembling what identifycpu() prints out. A few bytes saved by using
%b to format the features list rather than lots of ifs.
new driver code, there are diffs to several other existing files
on the system and a man page.
This version of matcd implements the rest of the key ioctls related to
playing audio CDs and reading table of contents information from any
type of disc.
This update also corrects several problems detected since the original
version 1(10) was released. These include:
1. Jordons report on the kernel -c string problem.
2. A problem with the driver being confused by other types of
devices located at addresses it probes.
3. An old CD TOC wouldn't always be cleared after a disc change.
4. Cleaned up code so -Wall yields no warnings on 2.0 and later.
5. A problem with drive getting out of sync with the driver when
changing between CD-Data and CD-DA.
There have only been two reports from the field relating to problems
so either the first release isn't really being used or doesn't have
many problems.
If there are any problems with this submission, please let me know.

process-controlled (i.e., graphics) mode.
Implement the logic to use this hook from within pcvt. (I'm sure
Søren will do the syscons part RSN).
I've still got one occasion where the system stalled, but my attempts
to trigger the situation artificially resulted int the expected
behaviour. It's hard to track bugs without the console and DDB
available. :-/
old type (stty) ioctls can easily bypass locking bits.
It involves manual conversion from old ioctls to new ones,
large piece of code duplicated from tty_compat.c
after ttioctl too, because it can change t_line.
Remove (TS_CNTTB | TS_LNCH) test, it is always inherits from
old tty mode and can't be reach in currently setted mode.
o the includes are now properly done by <sys/foo.h> instead of "foo.h"
o a bunch of undeclared functions has been resolved
o pcvt finally supports devconfig
