/dev/mcd0a instead of /dev/mcd0d. This is more conforming to the /dev/cd0a
for the SCSI cdrom drives. It breaks the convention d the whole drive.
But the question is, do we really need partitions on cdrom drives ?
1) tty.c: gather all the info about the processes before calling ttyprintf
(which may block).
2) syscons.c: handle asynchronous output properly (data structures may
be corrupted otherwise).
Example:
Application use port cua01
Getty open ttyd1 (allocates rawq,outq,etc) and waits while application
done
Application quits, sioclose issued, ttyfree issued (getty calls revoke)
Getty awakes and goes to panic into initrb (NULL rawq)
now HUPCL set only in bidir case for callin lines
(this prevents set HUPCL on mouse)
comhardclose:
in addition to HUPCL case now DTR dropped for bidir case
if line was active in and no carrier present now.
(this prevents DTR sleep on mouse)

The transfer speed was only set in the retry after error, not when
switching drives.
it still looks a little suspicious that so many of the status codes are missing
so I'm not going to adopt all of the existing ones yet. Try to be more
descriptive in the use of hex constants.
Changes _only_ take effect if `options LAPTOP' is set.
Note: This one is distinctly dodgy. When my IDE drive spins back up from sleep
mode, it generates this `extra interrupt' condition by spinning back up and
generating an intr, though without any particular action required. This
message coming out every time is rather annoying, and thus disabled.
However, what I'm not at all sure of is whether or not all IDE drives will
behave in the same way, or if perhaps it needs to be done in a more complicated
fashion by detecting this more involved "I've spun up and am just saying hi"
condition. This is a simple change and easy to back out/ammend if anybody has
any better ideas.
hack in the moment for testing purposes and to get the drive going
again.
0x20 means empty drive.
0x30 means closed drive with CDROM inserted.
0x80 means drive pulled out, but door closed.
0xa0 means drive pulled out and door open.
Luckily none of these values are the same as that reported for Ethernet
cards ( 0 for WD8003E, 0x40 for WD8013EPC, 0x60 for NE2000).
The bad part is, the probe code gets the WD8003E so hosed, that it is
no longer usable after it. No problem with the WD8013EPC.
my previous fix too (using wdp_heads controller value) and check
0 heads case too.
Other fixes from Bruce:
2) Fix dk_timeout from 2 to about 4 seconds.
3) wdcontrol not retried on internal error.
4) wdwait return check changed ( "!=0" to "<0" into wdsetctlr,
"<0" to "!=0" into wdgetctlr).
This inetrface should be used from now on.
pseudo device pty xx still keeps its meaning: a maximum of
xx ptys is allowed.
A ringbuffer is now 2040 bytes long, per Garrett Wollman's request.
The changes are inspired by the way NetBSD did it (thanks for that!),
though I made it slihghtly different, including the interface so
at least 75% of the allocated space is deallocated when the tty is
closed.
Note further that it is easy to modify the ringbuffer length runtime.
This will have to wait untill some later date...

Subject: Bugfix for SB16 with DSP version 4 and above
No description sent, but it appears to fix a major number problem
with certain models of the SB16.
Small hack, if heads > 16, output a warning and then set the head
count to 16. This stops the infinite loop on this error and allows
people to later fix the DOS parameter table later with fdisk.
run Exabyte 8505 on 1742's. This may not be the final solution, but it
makes it work. It may be better to change the DELAY(10) to DELAY(30)
inside the loop instead of increasing the loop count from 100 to 300.
Subject: Bug Fix for ft.c - please commit
Date: Mon, 14 Feb 94 10:22:54 CST
This fixes a bug where the system can crash if the tape is used
after the floppy has been used.
When the keyboard is probed, the LED's blink quickly and
"Keyboard reset failed" is printed on the console. The
init routine keeps trying endlessly with the same behavior
as above.
I got the latest -current sup sources (06-Feb-94 12:00 GMT) to work using the
old syscons.c. The following patch makes the new syscons work:
2) Make SNAKE_SAVER like default, if no saver specified in "options"
3) Remove #ifdef STAR_SAVER before line /* make screensaver happy */
this code needed in any case.
Subject: syscons-1.3
Date: Sat, 29 Jan 94 23:33:50 MET
But here is the (hopefully) final syscons-1.3....
....
I've changed sgetc so it works as the pccons parallel
(it now uses a scgetc internally).
[
There were a couple changes that Bruce Evans sent me that were applied
to this version along with some changes that S'ren didn't incorporate
into the final version. There will be only minor changes if anything
from this version to his final release.
]
o merged and fixed timeout code from sos.
o merged DOS partition support from sos.
o fixed "extra" interrupts.
o check if malloc retuns NULL :-(.
o print drive size as in NetBSD
o after an error, return the residual count, not 0.
o give up early for > 16 heads.
o cleaned up the old-drive detection in wdgetctlr().
o rewrote wddump(). I'd been putting this off because
I'd had the dump disabled since 0.0 and had no idea
if even the standard version worked. It didn't:
(0) syscons' sgetc() interface broke some keyboard
stuff.
(1) CADDR1 is mapped using pmap() and pmap got a NULL
pointer trap (at least when I got to wddump() using
call diediedie from ddb) because the pte for CADDR1
is only supposed to be hacked on directly (e.g. in
physcopyseg()).
(2) bad144 handling was not done.
(3) it was slooow (3600 sectors/minute) because my
controller doesn't cache writes.
o miscellaneous other cleanups, e.g., removed scattered
patchkit/terry dates.
o lots of reformatting.
To be done:
o Merge/fix TIH/NetBSD bad144 code (doesn't belong in any
particular driver. Why aren't we using i386/dkbad.c?).
o Merge/fix Dyson/NetBSD clustering code (large parts
should be shared).
o Fix/extend the partition in use bits. Support extended
partitions. This should be shared by all disk drivers. Swap
to a DOS partition so that the swap space can be shared with
linux.
o Don't use polling except for initialization. Need to
reorganise the state machine. Then "extra" interrupts
shouldn't happen (except maybe one for initialization).
o Fix disklabel, boot and driver inconsistencies with
bad144 in standard versions.
o Look at latest linux clustering methods. Our disksort()
gets in the way of clustering.
o cleaned up the ATA changes (needs more work. I think
the ATA specs say that the only thing really wrong with
the original version of wx is that there was no test
for drive-ready before some commands. 400 nsec delay
suffices for almost everything and 400 nsec delay is
usually "free").
netmask or impmask.
2) Fixes from Bruce:
o Changed name of schedsoftcom() to setsofttty() to match
setsoftclock()
o Bool_t isn't used.
o tx_fifo_size is 1 for chips without fifos, 16 for 16550's, to
help to output more efficiently for 16550's (LSR_TXRDY means
that the fifo is empty, not that it has space for one char).
o Changed name of softsio1() to siopoll() and merged compoll()
into siopoll().
o The probe forgot to clear com_mcr after it failed. This is
harmful for 4 single serial ports on 2 interrupts. It makes
partial misconfigurations worse.
o Don't bother initializing static variables that are 0 (bidir
stuff).
o Only initialize t_oflag to TTYDEF_OFLAG if unit == COMCONSOLE,
not if COMCONSOLE is defined.
o Don't call siointr() from comparam() if there is no output in
progress. For the call from sioopen(), there's no output in
progress, and siointr() often saw silo overflows for stale
input because it was called before sioopen() discarded the
input.
o Let ttselect() do the work for select(), so that the fixes for
ttselect() don't have to be duplicated in zillions of drivers.
Yes, I know that IFADDR ioctl is supposed to be deprecated... Note
that the patch was modified by me to fit better into the driver. -DG

While porting CAP to 386bsd/pk0.2.4 and now to FreeBSD Release 1.0
I found a couple of bugs associated with the packet filter. Here
are the fixes. I'm posting them here because they apply to
FreeBSD and 386bsd/pk0.2.4 and possibly to other *BSD.
The first occurs when using the packet filter to write raw
ethernet packets. The header consisting of the sender and
destination addresses and the protocol is removed and later
added back on, but with the byte order of the protocol reversed.
The fix ensures that the byte order in the protocol field is
swapped when it is removed.
The second fix ensures that SIOCGIFADDR works for BPF as claimed
in the man pages, by adding it to the ed driver. Similar fixes
will be needed for other ethernet drivers.

file override to disable fifo on 16550s:
I bought a board with two 16550's, but one of those ports has a mouse
on it. The sio driver always enables the fifo, which is a bad thing
for mice and X. The mouse is jerky and hard to use. The simple thing
is be to treat one of the ports as a non-fifo'ed UART, and I use the
flags option in my config file.
So, my config file has:
device sio0 at isa? port "IO_COM1" tty irq 4 flags 0x2 vector siointr
device sio1 at isa? port "IO_COM2" tty irq 3 vector siointr
(patch deleted)
Cuddle { braces up where possible on if statements
Add missing splx(s) calls before some returns.
Remove extra semicolon that was keeping uha_init from returning
before the timeout occured. This should speed probing up quite
a bit!
0) FreeBSD additional include files additions
1) Rod's arpacom changes
2) Function type and return code cleanup, and all functions have correct
casting to the correct data types
3) Bugfix where driver would not function due to missing structure not
given a value.
4) General cleanup. (Theo did a lot already, I just did some more)

As reported on the -bugs list by some one, and confirmed by Julian:
> I increased AHA_RESET_TIMEOUT in aha1542.c from 1000 to 10000
> and now my 1542C is found everytime.
Changed the output of the isa probe routine, that only devices, that
have an IO address and are smaller than 0x100 to be on the motherboard.
The seagate SCSI adapter is an example of a card, that doesn't have
an IO address and works only memory mapped.
