07-Sep-98 9/pc/devi82365.rc
===========================
Backport of the Brazil devi82365 to Plan9. One effect of

These are all minor changes. A b.com image is available in the same directory.
03-Sep-97 cmd/aux/vga
=====================
The following change allows the ViRGE/VX cards to work at 640x480x8 and
800x600x8. Unfortunately the hardware cursor refuses to work at 640x480x8,
no idea why.

02-Sep-97 9/contrib/dpt
=======================
This is a clarification from Mark Salyzyn (dpt.com!salyzyn_mark) of the
hardware supported by the DPT driver:
All the PCI cards made by DPT will work with this driver. These cards include
the PM2024, PM2124, PM2044, PM2144, PM3224 and PM3334. RAID and Cache
support is part of the firmware of the card and needs no driver support
to utilize these features. The PM3334 supports, with the appropriately
wired backplane, HOT target swapping (for RAID arrays).
The add-on features supported by the DPT controller card and Plan 9 driver
include:
1) Up to 64MB of configurable cache.
2) Firmware RAID-0 (striping), RAID-1 (mirroring) and RAID-5 (multi-
drive redundant arrays of up to 18 drives each).
3) Hot Swapping of targets in RAID-1 and RAID-5 arrays, with
appropriate hardware.
4) Hot Spares
The features not supported at this moment:
1) Command Queueing (? a driver/OS issue).
2) Passthrough (allowing native OS configuration and rebuilding of
arrays).
3) Software RAID (striping of arrays across adapters).
4) Multichannel Cards (The PM3334 can support up to 3 wide SCSI
channels).
5) Server-On-Call redundant server.
Sincerely -- Mark Salyzyn Senior Software Engineer
Distributed Processing Technology
23-Aug-97 9/contrib/dpt
=======================
This is a pci only driver for the DPT PM3334UW SmartRAID IV Ultra adapter.
It is a basic driver and does not use any of the advance features of the card.
The 9/pc & boot/pc drivers have been tested, but the fs/pc driver has not.
Thanks to
John L. Chmielewski, jlc@att.com
19-Aug-97 cmd/aux/vga/871963795.rc

Determining the memory size on the 543x chips is different.
3) vga.h clgd542x.c data.c
Add hwgc support.
from 12-Jun-97
1) trio64.c virge.c
Add support for the ViRGE/VX. Up to 1600x1200 supported, can't

Catch database entry with no 'ctlr='.
2) clgd542x.c
Recognise CL-GD7543.

==============================================
This is a change from Russ Cox to make it easy to
add new keyboard sequences for unicode characters.
First run the rc script to change latin1.c to use
latin1.h instead of having the sequences in latin1.c.
Then, to add new sequences:
1) add the new sequences to /lib/keyboard
2) in /sys/src/9/port run the command
aux/mklatinkbd /lib/keyboard > latin1.h
3) remake the kernel
21-Mar-97 cmd/ip/858963972.rc

support
for suggesting adjusting the timing values.
3) vision864.c
Fix typo in comment.

11-Sep-95 boot/pc/810864149.rc
==============================
bb.s Typo in comment.
bootp.c Improve timeout behaviour.
clock.c Add microdelay routine.
console.c Remove redundant argument to getstr.
dat.h Add typedef for PCIcfg;
Add declaration of ethernet broadcast address array.
donprint.c 'X' format character added.
dosboot.c Change definition of 'chatty' to remove unused code.
ether.c Improve timeout behaviour;
Add AMD79C970 and ELNK3 to table of known cards;
ether.h Add amd79c970reset prototype and increase number of
transmit buffers to 2.
ether509.c Don't enable 'update statistics' interrupts;
Loop in interrupt handler until all interrupt bits are
off to prevent losing an interrupt. Seems to happen on the
newer 3C509B cards;
Recognise 3C590 PCI cards.
ether79c970.c New. AMD79C970 driver.
ether8003.c Recognise 8216 cards (SMC Elite Ultra).
ether8390.c Add a mask to the ISR for the 8216 which seems to always
leave some bits on.
floppy.c Retry on DMA overrun;
Make timeouts processor-speed independent.
fns.h Change prototype for getstr to remove redundant argument;
Add prototypes for microdelay, pcicfgr, pcimatch.
hard.c Fix determination of drive geometry to have sensible
limits and to work in the presence of errors.
io.h Add PCIcfg structure and other PCI definitions.
l.s Always set VGA mode 3 due to Windows95 bogosity;
Typo in comment.

11-Sep-95 9/port/810872359.rc
=============================
devfloppy.c Retry on DMA overrun.
11-Sep-95 9/pc/810873946.rc
===========================
adaptec.c Unlock the mailbox interface on the 1542C/CF if necessary.
dat.h Define some extra floppy controller status bits.
devata.c Fix some timeout loops and be more careful in the presence
of bad ident data.
devi82365.c Set interrupt type.
ether509.c Loop in interrupt handler until all interrupt bits are
off to prevent losing an interrupt. Seems to happen on the
newer 3C509B cards;
Output data 32-bits at a time rather than 16.
kbd.c Disable the mouse port at startup.
mem.h Correct value for KTZERO so that kernel profiling works.
vgatvp3020.c Colours of hardware cursor were reversed.
11-Sep-95 cmd/aux/vga/810871888.rc
==================================
29-Aug-95
=========
1) trio64.c
Take out redundant code and fix memory timing for slower DRAM.
10-Aug-95
=========
1) ch9294.c ics2494.c
Fix botch in table-lookups introduced on 08-Aug-95.
09-Aug-95
=========
1) data.c mkfile trio64.c (new) vga.h
/lib/vgadb
Support for Trio32/Trio64.
There's a bug at high resolutions causing a thin white stripe to appear
between the right edge of the display and the border.
2) X ,x/Frequency/c/RefFreq/
X ,x/vmb/c/vmz/
3) db.c mach32.c main.c vga.h
BIOS override hack. Sometimes it's not possible to read the BIOS if
shadowing is off (Gateway + Phoenix BIOS?) and the search for a
matching
ctlr string fails (the symptom is aux/vga complains "controller not in
/lib/vgadb" but doesn't dump a portion of the BIOS to enable a ctlr
entry
id-string to be made. To overcome this problem the id-string can be
specified either as an argument (-b string) or as an environment
variable
(vgactlr=string, can be in plan9.ini). E.g.
aux/vga -b '0xC008F=ATI ULTRA PRO'
or
vgactlr=0xC008F=ATI ULTRA PRO
The mach32 is now assumed to have its extended registers at 0x1CE
instead of
attempting to read their address from the BIOS.
4) data.c ics534x.c (new) mkfile vga.h
/lib/vgadb
ICS534x GENDAC found on the newer Hercules Dynamite Power PCI cards.
08-Aug-95
=========
1) data.c mkfile s3clock.c tvp3025.c tvp3025clock.c vision964.c (new)
vga.h
/lib/vgadb
Support for #9GXE64pro.
2) main.c
Don't turn off the display during a load until necessary and leave it
off while the hardware cursor is turned on/off.
3) att20c49x.c att21c498.c data.c vga.h
Add trivial ctlr entry for att20c490 ramdac and tweak ramdac 'magic
access'
code.
4) att21c498.c
Lower threshold at which att21c498 will use 2x8-bit mode to > 80MHz.
5) ch9294.c et4000.c ics2494.c vga.h
Add "-e" and "-k tables for the Chrontel CH9294 clock generator and
look for
clock-divisors on the CH9294 and ICS2494 if asked for (ET4000).
6) /lib/vgadb
Change BIOS id-string for the Hercules Dynamite Power PCI and add ctlr
entry
for the ISA version.

default use ANSI's specification for multibyte and wide
characters.
17-Jul-95 cmd/ndb/dns.rc
========================
several The version of dns on the distribution has a number of memory
leaks. While fixing the leak, we added better cleaning of
the
