21 Introduction to ARCnet
22 ======================
24 ARCnet is a network type which works in a way similar to popular Ethernet
25 networks but which is also different in some very important ways.
27 First of all, you can get ARCnet cards in at least two speeds: 2.5 Mbps
28 (slower than Ethernet) and 100 Mbps (faster than normal Ethernet). In fact,
29 there are others as well, but these are less common. The different hardware
30 types, as far as I'm aware, are not compatible and so you cannot wire a
31 100 Mbps card to a 2.5 Mbps card, and so on. From what I hear, my driver does
32 work with 100 Mbps cards, but I haven't been able to verify this myself,
33 since I only have the 2.5 Mbps variety. It is probably not going to saturate
34 your 100 Mbps card. Stop complaining. :)
36 You also cannot connect an ARCnet card to any kind of Ethernet card and
39 There are two "types" of ARCnet - STAR topology and BUS topology. This
40 refers to how the cards are meant to be wired together. According to most
41 available documentation, you can only connect STAR cards to STAR cards and
42 BUS cards to BUS cards. That makes sense, right? Well, it's not quite
43 true; see below under "Cabling."
45 Once you get past these little stumbling blocks, ARCnet is actually quite a
46 well-designed standard. It uses something called "modified token passing"
47 which makes it completely incompatible with so-called "Token Ring" cards,
48 but which makes transfers much more reliable than Ethernet does. In fact,
49 ARCnet will guarantee that a packet arrives safely at the destination, and
50 even if it can't possibly be delivered properly (ie. because of a cable
51 break, or because the destination computer does not exist) it will at least
52 tell the sender about it.
54 Because of the carefully defined action of the "token", it will always make
55 a pass around the "ring" within a maximum length of time. This makes it
56 useful for realtime networks.
58 In addition, all known ARCnet cards have an (almost) identical programming
59 interface. This means that with one ARCnet driver you can support any
60 card, whereas with Ethernet each manufacturer uses what is sometimes a
61 completely different programming interface, leading to a lot of different,
62 sometimes very similar, Ethernet drivers. Of course, always using the same
63 programming interface also means that when high-performance hardware
64 facilities like PCI bus mastering DMA appear, it's hard to take advantage of
65 them. Let's not go into that.
67 One thing that makes ARCnet cards difficult to program for, however, is the
68 limit on their packet sizes; standard ARCnet can only send packets that are
69 up to 508 bytes in length. This is smaller than the Internet "bare minimum"
70 of 576 bytes, let alone the Ethernet MTU of 1500. To compensate, an extra
71 level of encapsulation is defined by RFC1201, which I call "packet
72 splitting," that allows "virtual packets" to grow as large as 64K each,
73 although they are generally kept down to the Ethernet-style 1500 bytes.
75 For more information on the advantages and disadvantages (mostly the
76 advantages) of ARCnet networks, you might try the "ARCnet Trade Association"
82 Cabling ARCnet Networks
83 =======================
85 This section was rewritten by
87 Vojtech Pavlik <vojtech@suse.cz>
89 using information from several people, including:
91 - Avery Pennraun <apenwarr@worldvisions.ca>
92 - Stephen A. Wood <saw@hallc1.cebaf.gov>
93 - John Paul Morrison <jmorriso@bogomips.ee.ubc.ca>
94 - Joachim Koenig <jojo@repas.de>
96 and Avery touched it up a bit, at Vojtech's request.
98 ARCnet (the classic 2.5 Mbps version) can be connected by two different
99 types of cabling: coax and twisted pair. The other ARCnet-type networks
100 (100 Mbps TCNS and 320 kbps - 32 Mbps ARCnet Plus) use different types of
101 cabling (Type1, Fiber, C1, C4, C5).
103 For a coax network, you "should" use 93 Ohm RG-62 cable. But other cables
104 also work fine, because ARCnet is a very stable network. I personally use 75
105 Ohm TV antenna cable.
107 Cards for coax cabling are shipped in two different variants: for BUS and
108 STAR network topologies. They are mostly the same. The only difference
109 lies in the hybrid chip installed. BUS cards use high impedance output,
110 while STAR use low impedance. Low impedance card (STAR) is electrically
111 equal to a high impedance one with a terminator installed.
113 Usually, the ARCnet networks are built up from STAR cards and hubs. There
114 are two types of hubs - active and passive. Passive hubs are small boxes
115 with four BNC connectors containing four 47 Ohm resistors::
119 -R-+-R- R 47 Ohm resistors
123 The shielding is connected together. Active hubs are much more complicated;
124 they are powered and contain electronics to amplify the signal and send it
125 to other segments of the net. They usually have eight connectors. Active
126 hubs come in two variants - dumb and smart. The dumb variant just
127 amplifies, but the smart one decodes to digital and encodes back all packets
128 coming through. This is much better if you have several hubs in the net,
129 since many dumb active hubs may worsen the signal quality.
131 And now to the cabling. What you can connect together:
133 1. A card to a card. This is the simplest way of creating a 2-computer
136 2. A card to a passive hub. Remember that all unused connectors on the hub
137 must be properly terminated with 93 Ohm (or something else if you don't
138 have the right ones) terminators.
140 (Avery's note: oops, I didn't know that. Mine (TV cable) works
143 3. A card to an active hub. Here is no need to terminate the unused
144 connectors except some kind of aesthetic feeling. But, there may not be
145 more than eleven active hubs between any two computers. That of course
146 doesn't limit the number of active hubs on the network.
148 4. An active hub to another.
150 5. An active hub to passive hub.
152 Remember that you cannot connect two passive hubs together. The power loss
153 implied by such a connection is too high for the net to operate reliably.
155 An example of a typical ARCnet network::
158 S------H--------A-------S R - Terminator
166 The BUS topology is very similar to the one used by Ethernet. The only
167 difference is in cable and terminators: they should be 93 Ohm. Ethernet
168 uses 50 Ohm impedance. You use T connectors to put the computers on a single
169 line of cable, the bus. You have to put terminators at both ends of the
170 cable. A typical BUS ARCnet network looks like::
172 RT----T------T------T------T------TR
179 But that is not all! The two types can be connected together. According to
180 the official documentation the only way of connecting them is using an active
183 A------T------T------TR
189 The official docs also state that you can use STAR cards at the ends of
190 BUS network in place of a BUS card and a terminator::
192 S------T------T------S
195 But, according to my own experiments, you can simply hang a BUS type card
196 anywhere in middle of a cable in a STAR topology network. And more - you
197 can use the bus card in place of any star card if you use a terminator. Then
198 you can build very complicated networks fulfilling all your needs! An

206 S------A------T-------T-------A-------H------TR
210 S------H---A----S | |
211 | | S------T----H---S |
214 A basically different cabling scheme is used with Twisted Pair cabling. Each
215 of the TP cards has two RJ (phone-cord style) connectors. The cards are
216 then daisy-chained together using a cable connecting every two neighboring
217 cards. The ends are terminated with RJ 93 Ohm terminators which plug into
218 the empty connectors of cards on the ends of the chain. An example::
220 ___________ ___________
223 |Card | |Card | |Card |
224 |_____| |_____| |_____|
227 There are also hubs for the TP topology. There is nothing difficult
228 involved in using them; you just connect a TP chain to a hub on any end or
229 even at both. This way you can create almost any network configuration.
230 The maximum of 11 hubs between any two computers on the net applies here as
233 RP-------P--------P--------H-----P------P-----PR
235 RP-----H--------P--------H-----P------PR
243 Like any network, ARCnet has a limited cable length. These are the maximum
244 cable lengths between two active ends (an active end being an active hub or
247 ========== ======= ===========
248 RG-62 93 Ohm up to 650 m
249 RG-59/U 75 Ohm up to 457 m
250 RG-11/U 75 Ohm up to 533 m
251 IBM Type 1 150 Ohm up to 200 m
252 IBM Type 3 100 Ohm up to 100 m
253 ========== ======= ===========
255 The maximum length of all cables connected to a passive hub is limited to 65
256 meters for RG-62 cabling; less for others. You can see that using passive
257 hubs in a large network is a bad idea. The maximum length of a single "BUS
258 Trunk" is about 300 meters for RG-62. The maximum distance between the two
259 most distant points of the net is limited to 3000 meters. The maximum length
260 of a TP cable between two cards/hubs is 650 meters.
266 All ARCnet cards should have a total of four or five different settings:
268 - the I/O address: this is the "port" your ARCnet card is on. Probed
269 values in the Linux ARCnet driver are only from 0x200 through 0x3F0. (If
270 your card has additional ones, which is possible, please tell me.) This
271 should not be the same as any other device on your system. According to
272 a doc I got from Novell, MS Windows prefers values of 0x300 or more,
273 eating net connections on my system (at least) otherwise. My guess is
274 this may be because, if your card is at 0x2E0, probing for a serial port
275 at 0x2E8 will reset the card and probably mess things up royally.
277 - Avery's favourite: 0x300.
279 - the IRQ: on 8-bit cards, it might be 2 (9), 3, 4, 5, or 7.
280 on 16-bit cards, it might be 2 (9), 3, 4, 5, 7, or 10-15.
282 Make sure this is different from any other card on your system. Note
283 that IRQ2 is the same as IRQ9, as far as Linux is concerned. You can
284 "cat /proc/interrupts" for a somewhat complete list of which ones are in
285 use at any given time. Here is a list of common usages from Vojtech
286 Pavlik <vojtech@suse.cz>:
288 ("Not on bus" means there is no way for a card to generate this
291 ====== =========================================================
292 IRQ 0 Timer 0 (Not on bus)
293 IRQ 1 Keyboard (Not on bus)
294 IRQ 2 IRQ Controller 2 (Not on bus, nor does interrupt the CPU)
297 IRQ 5 FREE (LPT2 if you have it; sometimes COM3; maybe PLIP)
298 IRQ 6 Floppy disk controller
299 IRQ 7 FREE (LPT1 if you don't use the polling driver; PLIP)
300 IRQ 8 Realtime Clock Interrupt (Not on bus)
301 IRQ 9 FREE (VGA vertical sync interrupt if enabled)
305 IRQ 13 Numeric Coprocessor (Not on bus)
306 IRQ 14 Fixed Disk Controller
307 IRQ 15 FREE (Fixed Disk Controller 2 if you have it)
308 ====== =========================================================
313 IRQ 9 is used on some video cards for the "vertical retrace"
314 interrupt. This interrupt would have been handy for things like
315 video games, as it occurs exactly once per screen refresh, but
316 unfortunately IBM cancelled this feature starting with the original
317 VGA and thus many VGA/SVGA cards do not support it. For this
318 reason, no modern software uses this interrupt and it can almost
319 always be safely disabled, if your video card supports it at all.
321 If your card for some reason CANNOT disable this IRQ (usually there
322 is a jumper), one solution would be to clip the printed circuit
323 contact on the board: it's the fourth contact from the left on the
324 back side. I take no responsibility if you try this.
326 - Avery's favourite: IRQ2 (actually IRQ9). Watch that VGA, though.
328 - the memory address: Unlike most cards, ARCnets use "shared memory" for
329 copying buffers around. Make SURE it doesn't conflict with any other
330 used memory in your system!
334 A0000 - VGA graphics memory (ok if you don't have VGA)
335 B0000 - Monochrome text mode
336 C0000 \ One of these is your VGA BIOS - usually C0000.
340 Anything less than 0xA0000 is, well, a BAD idea since it isn't above
343 - Avery's favourite: 0xD0000
345 - the station address: Every ARCnet card has its own "unique" network
346 address from 0 to 255. Unlike Ethernet, you can set this address
347 yourself with a jumper or switch (or on some cards, with special
348 software). Since it's only 8 bits, you can only have 254 ARCnet cards
349 on a network. DON'T use 0 or 255, since these are reserved (although
350 neat stuff will probably happen if you DO use them). By the way, if you
351 haven't already guessed, don't set this the same as any other ARCnet on
354 - Avery's favourite: 3 and 4. Not that it matters.
356 - There may be ETS1 and ETS2 settings. These may or may not make a
357 difference on your card (many manuals call them "reserved"), but are
358 used to change the delays used when powering up a computer on the
359 network. This is only necessary when wiring VERY long range ARCnet
360 networks, on the order of 4km or so; in any case, the only real
361 requirement here is that all cards on the network with ETS1 and ETS2
362 jumpers have them in the same position. Chris Hindy <chrish@io.org>

395 their own particular ARCnet cards. It is officially a mess, and contains
396 huge amounts of duplicated information. I have no time to fix it. If you
397 want to, PLEASE DO! Just send me a 'diff -u' of all your changes.

405 tell me. I had to figure mine out without the manual, and it WASN'T FUN!

459 About the jumpers: On my PC130 there is one more jumper, located near the
460 cable-connector and it's for changing to star or bus topology;
461 closed: star - open: bus
462 On the PC500 are some more jumper-pins, one block labeled with RX,PDN,TXI

719 *) To enable the 8K Boot PROM install the jumper ROM.
720 The default is jumper ROM not installed.
723 Setting the Timeouts and Interrupt
724 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
726 The jumpers labeled EXT1 and EXT2 are used to determine the timeout
727 parameters. These two jumpers are normally left open.
729 To select a hardware interrupt level set one (only one!) of the jumpers
730 IRQ2, IRQ3, IRQ4, IRQ5, IRQ7. The Manufacturer's default is IRQ2.
733 Configuring the PC130E for Star or Bus Topology
734 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
736 The single jumper labeled STAR is used to configure the PC130E board for
737 star or bus topology.
738 When the jumper is installed, the board may be used in a star network, when
739 it is removed, the board can be used in a bus topology.
745 Two diagnostic LEDs are visible on the rear bracket of the board.
746 The green LED monitors the network activity: the red one shows the
749 Green | Status Red | Status

752 blink | reconfiguration off | no data transfer;
753 off | defective board or | incorrect memory or
754 | node ID is zero | I/O address
757 PC500/PC550 Longboard (16-bit cards)
758 ------------------------------------
760 - from Juergen Seifert <seifert@htwm.de>
765 There is another Version of the PC500 called Short Version, which
766 is different in hard- and software! The most important differences
769 - The long board has no Shared memory.
770 - On the long board the selection of the interrupt is done by binary
771 coded switch, on the short board directly by jumper.
773 [Avery's note: pay special attention to that: the long board HAS NO SHARED
774 MEMORY. This means the current Linux-ARCnet driver can't use these cards.
775 I have obtained a PC500Longboard and will be doing some experiments on it in
776 the future, but don't hold your breath. Thanks again to Juergen Seifert for
777 his advice about this!]

789 The PC500 is equipped with a standard BNC female connector for connection
790 to RG-62/U coax cable.
791 The board is designed both for point-to-point connection in star networks
792 and for connection to bus networks.
794 The PC550 is equipped with two modular RJ11-type jacks for connection
795 to twisted pair wiring.
796 It can be used in a star or a daisy-chained (BUS) network.

886 Setting the I/O Base Address
887 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
889 The first six switches in switch group SW1 are used to select one
890 of 32 possible I/O Base addresses using the following table::
893 6 5 4 3 2 1 | Address
894 -------------|--------
909 0 1 1 1 1 0 | 2E0 (Manufacturer's default)
929 Setting the Interrupt
930 ^^^^^^^^^^^^^^^^^^^^^
932 Switches seven through ten of switch group SW1 are used to select the
933 interrupt level. The interrupt level is binary coded, so selections
934 from 0 to 15 would be possible, but only the following eight values will
935 be supported: 3, 4, 5, 7, 9, 10, 11, 12.
946 1 0 0 1 | 9 (=2) (default)
955 The two jumpers JP2 (1-4) are used to determine the timeout parameters.
956 These two jumpers are normally left open.
957 Refer to the COM9026 Data Sheet for alternate configurations.
960 Configuring the PC500 for Star or Bus Topology
961 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
963 The single jumper labeled JP6 is used to configure the PC500 board for
964 star or bus topology.
965 When the jumper is installed, the board may be used in a star network, when
966 it is removed, the board can be used in a bus topology.
972 Two diagnostic LEDs are visible on the rear bracket of the board.
973 The green LED monitors the network activity: the red one shows the
976 Green | Status Red | Status

980 off | defective board or | incorrect memory or
981 | node ID is zero | I/O address
987 - from J.S. van Oosten <jvoosten@compiler.tdcnet.nl>
989 Note: this data is gathered by experimenting and looking at info of other
990 cards. However, I'm sure I got 99% of the settings right.
992 The SMC710 card resembles the PC270 card, but is much more basic (i.e. no
993 LEDs, RJ11 jacks, etc.) and 8 bit. Here's a little drawing::
995 _______________________________________

1006 | .. JP1 +----------+ |
1012 |||||||||||||||||||||
1014 The row of jumpers at JP1 actually consists of 8 jumpers, (sometimes
1015 labelled) the same as on the PC270, from top to bottom: EXT2, EXT1, ROM,
1016 IRQ7, IRQ5, IRQ4, IRQ3, IRQ2 (gee, wonder what they would do? :-) )
1018 S1 and S2 perform the same function as on the PC270, only their numbers
1019 are swapped (S1 is the nodeaddress, S2 sets IO- and RAM-address).
1021 I know it works when connected to a PC110 type ARCnet board.

1029 LCS-8830(-T) (8 and 16-bit cards)
1030 ---------------------------------
1032 - from Mathias Katzer <mkatzer@HRZ.Uni-Bielefeld.DE>
1033 - Marek Michalkiewicz <marekm@i17linuxb.ists.pwr.wroc.pl> says the
1034 LCS-8830 is slightly different from LCS-8830-T. These are 8 bit, BUS
1035 only (the JP0 jumper is hardwired), and BNC only.
1037 This is a LCS-8830-T made by SMC, I think ('SMC' only appears on one PLCC,
1038 nowhere else, not even on the few Xeroxed sheets from the manual).

1149 --------------------
1151 - from Mark Rejhon <mdrejhon@magi.com> (slight modifications by Avery)
1152 - Avery's note: I think PDI508 cards (but definitely NOT PDI508Plus cards)
1153 are mostly the same as this. PDI508Plus cards appear to be mainly
1154 software-configured.
1158 There is a jumper array at the bottom of the card, near the edge
1159 connector. This array is labelled J1. They control the IRQs and
1160 something else. Put only one jumper on the IRQ pins.
1162 ETS1, ETS2 are for timing on very long distance networks. See the
1163 more general information near the top of this file.
1165 There is a J2 jumper on two pins. A jumper should be put on them,
1166 since it was already there when I got the card. I don't know what
1167 this jumper is for though.
1169 There is a two-jumper array for J3. I don't know what it is for,
1170 but there were already two jumpers on it when I got the card. It's
1171 a six pin grid in a two-by-three fashion. The jumpers were
1172 configured as follows::
1176 :-------: ------> Accessible end of card with connectors
1177 o | o o | in this direction ------->
1180 Carl de Billy <CARL@carainfo.com> explains J3 and J4:
1186 :-------: TWIST Technology
1191 :-------: COAX Technology
1195 - If using coax cable in a bus topology the J4 jumper must be removed;
1196 place it on one pin.
1198 - If using bus topology with twisted pair wiring move the J3
1199 jumpers so they connect the middle pin and the pins closest to the RJ11
1200 Connectors. Also the J4 jumper must be removed; place it on one pin of
1201 J4 jumper for storage.
1203 - If using star topology with twisted pair wiring move the J3
1204 jumpers so they connect the middle pin and the pins closest to the RJ11
1210 The DIP switches accessible on the accessible end of the card while
1211 it is installed, is used to set the ARCnet address. There are 8
1212 switches. Use an address from 1 to 254
1214 ========== =========================
1215 Switch No. ARCnet address
1217 ========== =========================
1218 00000000 FF (Don't use this!)
1224 11111111 0 (Don't use this!)
1225 ========== =========================
1227 There is another array of eight DIP switches at the top of the
1228 card. There are five labelled MS0-MS4 which seem to control the
1229 memory address, and another three labelled IO0-IO2 which seem to
1230 control the base I/O address of the card.
1232 This was difficult to test by trial and error, and the I/O addresses
1233 are in a weird order. This was tested by setting the DIP switches,
1234 rebooting the computer, and attempting to load ARCETHER at various
1235 addresses (mostly between 0x200 and 0x400). The address that caused
1236 the red transmit LED to blink, is the one that I thought works.
1238 Also, the address 0x3D0 seem to have a special meaning, since the
1239 ARCETHER packet driver loaded fine, but without the red LED
1240 blinking. I don't know what 0x3D0 is for though. I recommend using
1241 an address of 0x300 since Windows may not like addresses below
1244 ============= ===========
1245 IO Switch No. I/O address
1247 ============= ===========
1256 ============= ===========
1258 The memory switches set a reserved address space of 0x1000 bytes
1259 (0x100 segment units, or 4k). For example if I set an address of
1260 0xD000, it will use up addresses 0xD000 to 0xD100.
1262 The memory switches were tested by booting using QEMM386 stealth,
1263 and using LOADHI to see what address automatically became excluded
1264 from the upper memory regions, and then attempting to load ARCETHER
1265 using these addresses.
1267 I recommend using an ARCnet memory address of 0xD000, and putting
1268 the EMS page frame at 0xC000 while using QEMM stealth mode. That
1269 way, you get contiguous high memory from 0xD100 almost all the way
1270 the end of the megabyte.
1272 Memory Switch 0 (MS0) didn't seem to work properly when set to OFF
1273 on my card. It could be malfunctioning on my card. Experiment with
1274 it ON first, and if it doesn't work, set it to OFF. (It may be a
1275 modifier for the 0x200 bit?)

1416 Setting the I/O Base Address
1417 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1419 The last three switches in switch block SW1 are used to select one
1420 of eight possible I/O Base addresses using the following table::
1425 ------------|--------
1428 ON OFF ON | 2E0 (Manufacturer's default)
1436 Setting the Base Memory (RAM) buffer Address
1437 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1439 The memory buffer (RAM) requires 2K. The base of this buffer can be
1440 located in any of eight positions. The address of the Boot Prom is
1441 memory base + 8K or memory base + 0x2000.
1442 Switches 1-5 of switch block SW1 select the Memory Base address.
1446 Switch | Hex RAM | Hex ROM
1447 1 2 3 4 5 | Address | Address *)
1448 --------------------|---------|-----------

1455 ON ON ON OFF OFF | DC000 | DE000
1456 ON ON OFF OFF OFF | E0000 | E2000
1458 *) To enable the Boot ROM install the jumper JP1
1462 Since the switches 1 and 2 are always set to ON it may be possible
1463 that they can be used to add an offset of 2K, 4K or 6K to the base
1464 address, but this feature is not documented in the manual and I
1465 haven't tested it yet.
1468 Setting the Interrupt Line
1469 ^^^^^^^^^^^^^^^^^^^^^^^^^^
1471 To select a hardware interrupt level install one (only one!) of the jumpers
1472 JP2, JP3, JP4, JP5, JP6. JP2 is the default::
1483 Setting the Internal Terminator on CN120AB/TP/SBT
1484 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1486 The jumper JP12 is used to enable the internal terminator::
1495 Terminator Terminator
1499 Selecting the Connector Type on CN120ST/SBT
1500 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1508 | 0 | | 0 | | 0 | | 0 |
1512 Coaxial Cable Twisted Pair Cable
1516 Setting the Timeout Parameters
1517 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1519 The jumpers labeled EXT1 and EXT2 are used to determine the timeout
1520 parameters. These two jumpers are normally left open.

1582 Setting one of the switches to Off means "1", On means "0".
1588 The eight switches in SW2 are used to set the node ID. Each node attached
1589 to the network must have an unique node ID which must be different from 0.
1590 Switch 1 (ID0) serves as the least significant bit (LSB).
1592 The node ID is the sum of the values of all switches set to "1"

1625 Setting the I/O Base Address
1626 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1628 The first six switches in switch block SW1 are used to select the I/O Base
1629 address using the following table::
1632 1 2 3 4 5 6 | Address
1633 ------------------------|--------
1634 OFF ON ON OFF OFF ON | 260
1635 OFF ON OFF ON ON OFF | 290

1639 OFF OFF ON OFF ON OFF | 350
1640 OFF OFF OFF ON ON ON | 380
1641 OFF OFF OFF OFF OFF ON | 3E0
1643 Note: Other IO-Base addresses seem to be selectable, but only the above
1644 combinations are documented.
1647 Setting the Base Memory (RAM) buffer Address
1648 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1650 The switches 7-10 of switch block SW1 are used to select the Memory
1651 Base address of the RAM (2K) and the PROM::
1653 Switch | Hex RAM | Hex ROM
1654 7 8 9 10 | Address | Address
1655 ----------------|---------|-----------
1656 OFF OFF ON ON | C0000 | C8000
1657 OFF OFF ON OFF | D0000 | D8000 (Default)
1658 OFF OFF OFF ON | E0000 | E8000
1662 Other MEM-Base addresses seem to be selectable, but only the above
1663 combinations are documented.
1666 Setting the Interrupt Line
1667 ^^^^^^^^^^^^^^^^^^^^^^^^^^
1669 To select a hardware interrupt level install one (only one!) of the jumpers
1670 JP3 through JP13 using the following table::
1673 -------|-----------------
1684 13 | 2 (=9) Default!
1688 - Do not use JP11=IRQ6, it may conflict with your Floppy Disk
1690 - Use JP3=IRQ14 only, if you don't have an IDE-, MFM-, or RLL-
1691 Hard Disk, it may conflict with their controllers
1694 Setting the Timeout Parameters
1695 ------------------------------
1697 The jumpers labeled JP1 and JP2 are used to determine the timeout
1698 parameters. These two jumpers are normally left open.

1755 It seems that the bits are considered in reverse order. Also, you must
1756 observe that some of those addresses are unusual and I didn't probe them; I
1757 used a memory dump in DOS to identify them. For the 00000 configuration and
1758 some others that I didn't write here the card seems to conflict with the
1759 video card (an S3 GENDAC). I leave the full decoding of those addresses to

1787 --------------------------
1789 - from Vojtech Pavlik <vojtech@suse.cz> using portions of the existing
1790 arcnet-hardware file.
1792 This is a 90C26 based card. Its configuration seems similar to the SMC
1793 PC100, but has some additional jumpers I don't know the meaning of.

1865 The eight switches in SW2 are used to set the node ID. Each node attached
1866 to the network must have an unique node ID which must not be 0.
1867 Switch 1 (ID0) serves as the least significant bit (LSB).
1869 Setting one of the switches to OFF means "1", ON means "0".
1871 The node ID is the sum of the values of all switches set to "1"
1885 Don't set this to 0 or 255; these values are reserved.
1888 Setting the I/O Base Address
1889 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1891 The switches 1 to 6 of switch block SW1 are used to select one
1892 of 32 possible I/O Base addresses using the following tables::
1904 The I/O address is sum of all switches set to "1". Remember that
1905 the I/O address space bellow 0x200 is RESERVED for mainboard, so
1906 switch 1 should be ALWAYS SET TO OFF.
1909 Setting the Base Memory (RAM) buffer Address
1910 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1912 The memory buffer (RAM) requires 2K. The base of this buffer can be
1913 located in any of sixteen positions. However, the addresses below
1914 A0000 are likely to cause system hang because there's main RAM.
1916 Jumpers 7-10 of switch block SW1 select the Memory Base address::
1920 ----------------|---------
1921 OFF OFF OFF OFF | F0000 (conflicts with main BIOS)
1922 OFF OFF OFF ON | E0000
1923 OFF OFF ON OFF | D0000
1924 OFF OFF ON ON | C0000 (conflicts with video BIOS)
1925 OFF ON OFF OFF | B0000 (conflicts with mono video)
1926 OFF ON OFF ON | A0000 (conflicts with graphics)
1929 Setting the Interrupt Line
1930 ^^^^^^^^^^^^^^^^^^^^^^^^^^
1932 Jumpers 1-5 of the jumper block J1 control the IRQ level. ON means
1933 shorted, OFF means open::

1938 ON OFF OFF OFF OFF | 7
1939 OFF ON OFF OFF OFF | 5
1940 OFF OFF ON OFF OFF | 4
1941 OFF OFF OFF ON OFF | 3
1942 OFF OFF OFF OFF ON | 2
1945 Unknown jumpers & sockets
1946 ^^^^^^^^^^^^^^^^^^^^^^^^^
1948 I know nothing about these. I just guess that J16&J17 are timeout
1949 jumpers and maybe one of J18-J21 selects ROM. Also J6-J10 and
1950 J11-J15 are connecting IRQ2-7 to some pins on the UFSs. I can't
1956 LAN-ARC-8, an 8-bit card
1957 ------------------------
1959 - from Vojtech Pavlik <vojtech@suse.cz>
1961 This is another SMC 90C65-based ARCnet card. I couldn't identify the
1962 manufacturer, but it might be DataPoint, because the card has the
1963 original arcNet logo in its upper right corner.

2032 The last three switches in switch block SW1 are used to select one
2033 of eight possible I/O Base addresses using the following table::
2038 ------------|--------
2041 ON OFF ON | 2E0 (Manufacturer's default)
2049 Setting the Base Memory (RAM) buffer Address
2050 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2052 The memory buffer (RAM) requires 2K. The base of this buffer can be
2053 located in any of eight positions. The address of the Boot Prom is
2054 memory base + 0x2000.
2056 Jumpers 3-5 of switch block SW1 select the Memory Base address.

2296 "0" in the above example means switch is off "1" means that it is on.
2310 ENHANCED----------- 1
2311 COMPATIBLE--------- 0
2323 There is a DIP-switch with 8 switches, used to set the shared memory address
2324 to be used. The first 6 switches set the address, the 7th doesn't have any
2325 function, and the 8th switch is used to select "compatible" or "enhanced".
2326 When I got my two cards, one of them had this switch set to "enhanced". That
2327 card didn't work at all, it wasn't even recognized by the driver. The other
2328 card had this switch set to "compatible" and it behaved absolutely normally. I
2329 guess that the switch on one of the cards, must have been changed accidentally
2330 when the card was taken out of its former host. The question remains
2331 unanswered, what is the purpose of the "enhanced" position?
2333 [Avery's note: "enhanced" probably either disables shared memory (use IO
2334 ports instead) or disables IO ports (use memory addresses instead). This
2335 varies by the type of card involved. I fail to see how either of these
2336 enhance anything. Send me more detailed information about this mode, or
2337 just use "compatible" mode instead.]

2340 =============================
2344 - from Robert Michael Best <rmb117@cs.usask.ca>
2346 [Avery's note: these don't work with my driver for some reason. These cards
2347 SEEM to have settings similar to the PDI508Plus, which is
2348 software-configured and doesn't work with my driver either. The "Waterloo
2349 chip" is a boot PROM, probably designed specifically for the University of
2350 Waterloo. If you have any further information about this card, please
2353 The probe has not been able to detect the card on any of the J2 settings,
2354 and I tried them again with the "Waterloo" chip removed.

2559 ON OFF ON | 2E0 (Manufacturer's default)
2567 Setting the Base Memory (RAM) buffer Address
2568 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2570 The memory buffer requires 2K of a 16K block of RAM. The base of this
2571 16K block can be located in any of eight positions.
2572 Switches 4-6 of switch group SW2 select the Base of the 16K block.
2573 Within that 16K address space, the buffer may be assigned any one of four
2574 positions, determined by the offset, switches 7 and 8 of group SW2.

2879 Setting the jumpers to ON means connecting the upper two pins, off the bottom
2880 two - or - in case of IRQ setting, connecting none of them at all.
2885 The eight switches in SW2 are used to set the node ID. Each node attached
2886 to the network must have an unique node ID which must not be 0.
2887 Switch 1 (ID0) serves as the least significant bit (LSB).
2889 Setting one of the switches to Off means "1", On means "0".

2928 of eight possible I/O Base addresses using the following table::
2933 ------------|--------
2936 ON OFF ON | 2E0 (Manufacturer's default)
2944 Setting the Base Memory (RAM) buffer Address
2945 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2947 The memory buffer (RAM) requires 2K. The base of this buffer can be
2948 located in any of eight positions. The address of the Boot Prom is
2949 memory base + 0x2000.
2951 Jumpers 3-5 of jumper block SW1 select the Memory Base address.

3050 To select a hardware interrupt level set one (only one!) of the dip switches
3051 up (on) SW1...(switches 1-5)
3052 IRQ3, IRQ4, IRQ5, IRQ7, IRQ2. The Manufacturer's default is IRQ2.
3054 The switches on SW1 labeled EXT1 (switch 6) and EXT2 (switch 7)
3055 are used to determine the timeout parameters. These two dip switches
3056 are normally left off (down).
3058 To enable the 8K Boot PROM position SW1 switch 8 on (UP) labeled ROM.
3059 The default is jumper ROM not installed.
3062 Setting the I/O Base Address
3063 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
3065 The last three switches in switch group SW2 are used to select one
3066 of eight possible I/O Base addresses using the following table::
3074 0 1 0 | 2E0 (Manufacturer's default)
3082 Setting the Base Memory Address (RAM & ROM)
3083 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
3085 The memory buffer requires 2K of a 16K block of RAM. The base of this
3086 16K block can be located in any of eight positions.
3087 Switches 1-3 of switch group SW2 select the Base of the 16K block.
