This file is a supplement to README.arcnet. Please read that for general
driver configuration help.
-----------------------------------------------------------------------------
Because so many people (myself included) seem to have obtained ARCnet cards
without manuals, this will be a quick listing of all jumper settings I can
find. Please e-mail apenwarr@tourism.807-city.on.ca with any settings for
your particular card.
Even if your ARCnet model isn't listed, but has the same jumpers, please
e-mail me to say so.
If your model isn't listed, and has different settings, PLEASE PLEASE tell
me. I had to figure mine out without the manual, and it WASN'T FUN!

About the jumpers: On my PC130 there is one more jumper, located near the
cable-connector and it's for changing to star or bus topology;
closed: star - open: bus
On the PC500 are some more jumper-pins, one block labeled with RX,PDN,TXI
and another with ALE,LA17,LA18,LA19 these are undocumented..

Quick Briefing:
---------------
All ARCnet cards should have a total of four different settings:
- the I/O address: this is the "port" your ARCnet card is on. Probed
values, as of v0.14, are only from 0x200 through 0x3F0. (If your card
has additional ones, which is possible, please tell me.) This should not
be the same as any other device on your system. Supposedly MS Windows
prefers values of 0x300 or more, eating net connections on my system
otherwise.
- Avery's favourite: 0x300.
- the IRQ: on 8-bit cards, it might be 2 (9), 3, 4, 5, or 7.
on 16-bit cards, it might be 2 (9), 3, 4, 5, 7, or 9-15. Make
sure this is different from any other card on your system. Note that
IRQ2 is the same as IRQ9, as far as Linux is concerned.
- Avery's favourite: IRQ2.
- the memory address: Unlike most cards, ARCnets use "shared memory" for
copying buffers around. Make SURE it doesn't conflict with any other
used memory in your system!
A0000 - VGA graphics memory (ok if you don't have VGA)
B0000 - Monochrome text mode
C0000 \ One of these is your VGA BIOS - usually C0000.
E0000 /
F0000 - System BIOS
Anything less than 0xA0000 is, well, a BAD idea since it isn't above
640k.
- Avery's favourite: 0xD0000
- the station address: Every ARCnet card has its own "unique" network
address from 0 to 255. Unlike ethernet, you can set this address
yourself. Since it's only 8 bits, you can only have 254 ARCnet cards on
a network. DON'T use 0 or 255, since these are reserved. (although neat
stuff will probably happen if you DO use them). By the way, if you
haven't already guessed, don't set this the same as any other ARCnet on
your network!
- Avery's favourite: 3 and 4. Not that it matters.

===============================================================
This description has been written by Juergen Seifert <seifert@htwm.de>
using information from the following Original SMC Manual
"Configuration Guide for
ARCNET(R)-PC130E/PC270
Network Controller Boards
Pub. # 900.044A
June, 1989"
ARCNET is a registered trademark of the Datapoint Corporation
SMC is a registered trademark of the Standard Microsystems Corporation
The PC130E is an enhanced version of the PC130 board, is equipped with a
standard BNC female connector for connection to RG-62/U coax cable.
Since this board is designed both for point-to-point connection in star
networks and for connection to bus networks, it is downwardly compatible
with all the other standard boards designed for coax networks (that is,
the PC120, PC110 and PC100 star topology boards and the PC220, PC210 and
PC200 bus topology boards).
The PC270E is an enhanced version of the PC260 board, is equipped with two
modular RJ11-type jacks for connection to twisted pair wiring.
It can be used in a star or a daisy-chained network.

Setting one of the switches to Off/Open means "1", On/Closed means "0".
Setting the Node ID
-------------------
The eight switches in group S2 are used to set the node ID.
Each node attached to the network must have an unique node ID which
must be different from 0.
Switch 1 serves as the least significant bit (LSB).
The node ID is the sum of the values of all switches set to "1"
These values are:
Switch | Value
-------|-------
1 | 1
2 | 2
3 | 4
4 | 8
5 | 16
6 | 32
7 | 64

Setting the I/O Base Address
----------------------------
The first three switches in switch group S1 are used to select one
of eight possible I/O Base addresses using the following table
Switch | Hex I/O
1 2 3 | Address
-------|--------
0 0 0 | 260
0 0 1 | 290
0 1 0 | 2E0 (Manufacturer's default)
0 1 1 | 2F0
1 0 0 | 300
1 0 1 | 350
1 1 0 | 380
1 1 1 | 3E0
Setting the Base Memory (RAM) buffer Address
--------------------------------------------
The memory buffer requires 2K of a 16K block of RAM. The base of this
16K block can be located in any of eight positions.
Switches 4-6 of switch group S1 select the Base of the 16K block.
Within that 16K address space, the buffer may be assigned any one of four
positions, determined by the offset, switches 7 and 8 of group S1.

*) To enable the 8K Boot PROM install the jumper ROM.
The default is jumper ROM not installed.
Setting the Timeouts and Interrupt
----------------------------------
The jumpers labeled EXT1 and EXT2 are used to determine the timeout
parameters. These two jumpers are normally left open.
Refer to the COM9026 Data Sheet for alternate configurations.
To select a hardware interrupt level set one (only one!) of the jumpers
IRQ2, IRQ3, IRQ4, IRQ5, IRQ7. The manufacturer's default is IRQ2.
Configuring the PC130E for Star or Bus Topology
-----------------------------------------------
The single jumper labeled STAR is used to configure the PC130E board for
star or bus topology.
When the jumper is installed, the board may be used in a star network, when
it is removed, the board can be used in a bus topology.
Diagnostic LEDs
---------------
Two diagnostic LEDs are visible on the rear bracket of the board.
The green LED monitors the network activity: the red one shows the
board activity:
Green | Status Red | Status
-------|------------------- ---------|-------------------
on | normal activity flash/on | data transfer
blink | reconfiguration off | no data transfer;
off | defective board or | incorrect memory or
| node ID is zero | I/O address

STANDARD MICROSYSTEMS CORPORATION (SMC) ARCNET-PC500/PC550 Long Board
=====================================================================
Note: There is another Version of the PC500 called Short Version, which
is different in hard- and software! The most important differences
are:
- The long board has no Shared memory
- On the long board the selection of the interrupt is done by binary
coded switch, on the short board directly by jumper.

Setting the I/O Base Address
----------------------------
The first six switches in switch group SW1 are used to select one
of 32 possible I/O Base addresses using the following table
Switch | Hex I/O

Setting the Interrupt
---------------------
Switches seven through ten of switch group SW1 are used to select the
interrupt level. The interrupt level is binary coded, so selections
from 0 to 15 would be possible, but only the following eight values will
be supported: 3, 4, 5, 7, 9, 10, 11, 12.

1 0 1 0 | 10
1 0 1 1 | 11
1 1 0 0 | 12
Setting the Timeouts
--------------------
The two jumpers JP2 (1-4) are used to determine the timeout parameters.
These two jumpers are normally left open.
Refer to the COM9026 Data Sheet for alternate configurations.
Configuring the PC500 for Star or Bus Topology
----------------------------------------------
The single jumper labeled JP6 is used to configure the PC500 board for
star or bus topology.
When the jumper is installed, the board may be used in a star network, when
it is removed, the board can be used in a bus topology.

PDI507 (16-bit card)
--------------------
- from Mark Rejhon <mdrejhon@magi.com> (slight modifications by
Avery)
- Send questions/suggestions/etc about this text to Mark.
Jumpers:
There is a jumper array at the bottom of the card, near the edge
connector. This array is labelled J1. They control the IRQs and
something else. Put only one jumper on the IRQ pins.
IRQ2 - Use IRQ 2 (same as IRQ 9 as far as software is concerned)
IRQ3 - Use IRQ 3 (used by COM2 or COM4 serial port if either exists)
IRQ4 - Use IRQ 4 (used by COM1 or COM3 serial port if either exists)
IRQ5 - Use IRQ 5 (used by LPT2 parallel port if one exists)
IRQ6 - Use IRQ 6 (used by Floppy Disk Controller if one exists)
IRQ7 - Use IRQ 7 (used by LPT1 parallel port if one exists)
[Avery's note: This "unknown" set of two jumpers appears to be on all
ARCnet cards by SMC as well. Putting jumpers on them seems to affect the
status register, but only for the two "reserved" bits, ETS1 and ETS2. Any
further information is welcome.]
ET1 - What is this? (Not tested, no jumper put on it)
ET2 - What is this? (Not tested, no jumper put on it)
There is a J2 jumper on two pins. A jumper should be put on them,
since it was already there when I got the card. I don't know what
this jumper is for though.
There is a two-jumper array for J3. I don't know what it is for,
but there were already two jumpers on it when I got the card. It's
a six pin grid in a two-by-three fashion. The jumpers were
configured as follows:
.-------.
o | o o |
:-------: ------> Accessible end of card with connectors
o | o o | in this direction ------->
`-------'
There is also a J4 jumper on two pins. A jumper should be put on
them, since it was already there when I got the card. I don't know
what this jumper is for though.
DIP Switches:
The dip switches accessible on the accessible end of the card while
it is installed, is used to set the arcnet address. There are 8
switches. Use an address from 1 to 254.
Switch No.
12345678 Arcnet address

....
11111101 2
11111110 1
11111111 0 (Don't use this!)
There is another dipswitch array of 8 switches at the top of the
card. There are five labelled MS0-MS4 which seem to control the
memory address, and another three labelled IO0-IO2 which seem to
control the base I/O address of the card.
This was difficult to test by trial and error, and the I/O addresses
are in a weird order. This was tested by setting the DIP switches,
rebooting the computer, and attempting to load ARCETHER at various
addresses (mostly between 0x200 and 0x400). The address that caused
the red transmit LED to blink, is the one that I thought works.
Also, the address 0x3D0 seem to have a special meaning, since the
ARCETHER packet driver loaded fine, but without the red LED
blinking. I don't know what 0x3D0 is for though. I recommend using
an address of 0x300 since Windows may not like addresses below
0x300.
IO Switch No.
210 I/O address
-------------------------------
111 0x260
110 0x290
101 0x2E0
100 0x2F0
011 0x300
010 0x350
001 0x380
000 0x3E0
The memory switches set a reserved address space of 0x1000 bytes
(0x100 segment units, or 4k). For example if I set an address of
0xD000, it will use up addresses 0xD000 to 0xD100.
The memory switches were tested by booting using QEMM386 stealth,
and using LOADHI to see what address automatically became excluded
from the upper memory regions, and then attempting to load ARCETHER
using these addresses.
I recommend using an arcnet memory address of 0xD000, and putting
the EMS page frame at 0xC000 while using QEMM stealth mode. That
way, you get contiguous high memory from 0xD100 almost all the way
the end of the megabyte.
Memory Switch 0 (MS0) didn't seem to work properly when set to OFF
on my card. It could be malfunctioning on my card. Experiment with
it ON first, and if it doesn't work, set it to OFF. (It may be a
modifier for the 0x200 bit?)
MS Switch No.
43210 Memory address

J2 Two 6-position Telephone Jack (CN120TP/ST/SBT only)
Setting one of the switches to Off means "1", On means "0".
Setting the Node ID
-------------------
The eight switches in SW2 are used to set the node ID. Each node attached
to the network must have an unique node ID which must be different from 0.
Switch 1 (ID0) serves as the least significant bit (LSB).
The node ID is the sum of the values of all switches set to "1"
These values are:
Switch | Label | Value
-------|-------|-------
1 | ID0 | 1
2 | ID1 | 2
3 | ID2 | 4
4 | ID3 | 8
5 | ID4 | 16

1 1 1 1 1 1 1 1 | FF | 255
Setting the I/O Base Address
----------------------------
The last three switches in switch block SW1 are used to select one
of eight possible I/O Base addresses using the following table
Switch | Hex I/O
6 7 8 | Address
------------|--------
ON ON ON | 260
OFF ON ON | 290
ON OFF ON | 2E0 (Manufacturer's default)
OFF OFF ON | 2F0
ON ON OFF | 300
OFF ON OFF | 350
ON OFF OFF | 380
OFF OFF OFF | 3E0
Setting the Base Memory (RAM) buffer Address
--------------------------------------------
The memory buffer (RAM) requires 2K. The base of this buffer can be
located in any of eight positions. The address of the Boot Prom is
memory base + 8K or memory base + 0x2000.
Switches 1-5 of switch block SW1 select the Memory Base address.
Switch | Hex RAM | Hex ROM
1 2 3 4 5 | Address | Address *)
--------------------|---------|-----------
ON ON ON ON ON | C0000 | C2000
ON ON OFF ON ON | C4000 | C6000
ON ON ON OFF ON | CC000 | CE000
ON ON OFF OFF ON | D0000 | D2000 (Manufacturer's default)
ON ON ON ON OFF | D4000 | D6000
ON ON OFF ON OFF | D8000 | DA000
ON ON ON OFF OFF | DC000 | DE000
ON ON OFF OFF OFF | E0000 | E2000
*) To enable the Boot ROM install the jumper JP1
Note: Since the switches 1 and 2 are always set to ON it may be possible
that they can be used to add an offset of 2K, 4K or 6K to the base
address, but this feature is not documented in the manual and I
haven't tested it yet.
Setting the Interrupt Line
--------------------------
To select a hardware interrupt level install one (only one!) of the jumpers
JP2, JP3, JP4, JP5, JP6. JP2 is the default.

I have named this ARCnet card "NONAME", since there is no name of any
manufacturer on the Installation manual nor on the shipping box. The only
hint to the existence of a manufacturer at all is written into copper,
it is "Made in Taiwan"

Setting Interrupt Request Lines (IRQ)
-------------------------------------
To select a hardware interrupt level set one (only one!) of the jumpers
IRQ2, IRQ3, IRQ4, IRQ5 or IRQ7. The manufacturer's default is IRQ2.
Setting the Timeouts
--------------------
The two jumpers labeled ET1 and ET2 are used to determine the timeout
parameters (response and reconfiguration time). Every node in a network
must be set to the same timeout values.
ET1 ET2 | Response Time (us) | Reconfiguration Time (ms)
--------|--------------------|--------------------------
Off Off | 78 | 840 (Default)
Off On | 285 | 1680
On Off | 563 | 1680
On On | 1130 | 1680
On means jumper installed, Off means jumper not installed
NONAME 16-BIT ARCNET
====================
The manual of my 8-Bit NONAME ARCnet Card contains another description
of a 16-Bit Coax / Twisted Pair Card. This description is incomplete,
because there are missing two pages in the manual booklet. (The table
of contents reports pages ... 2-9, 2-11, 2-12, 3-1, ... but inside
the booklet there is a different way of counting ... 2-9, 2-10, A-1,
(empty page), 3-1, ..., 3-18, A-1 (again), A-2)
Also the picture of the board layout is not as good as the picture of
8-Bit card, because there isn't any letter like "SW1" written to the
picture.
Should somebody have such a board, please feel free to complete this
description or to send a mail to me!

The memory buffer requires 2K of a 16K block of RAM. The base of this
16K block can be located in any of eight positions.
Switches 6-8 of switch group SW1 select the Base of the 16K block.
Within that 16K address space, the buffer may be assigned any one of four
positions, determined by the offset, switches 4 and 5 of group SW1.
