This particular driver supports both the 3c90x and +- the 3c90xB revision cards. 3C90xC family support has been tested to some +- degree but not extensively. +- +- Here's the licensing information: +- +- This program Copyright (C) 1999 LightSys Technology Services, Inc. +- Portions Copyright (C) 1999 Steve Smith. +- +- This program may be re-distributed in source or binary form, modified, +- sold, or copied for any purpose, provided that the above copyright message +- and this text are included with all source copies or derivative works, and +- provided that the above copyright message and this text are included in the +- documentation of any binary-only distributions.

Please read the associated +- documentation "3c90x.txt" before compiling and using this driver. +- +- +-II FLASH PROMS +- +- The 3c90xB cards, according to the 3Com documentation, only accept the +- following flash memory chips: +- +- Atmel AT29C512 (64 kilobyte) +- Atmel AT29C010 (128 kilobyte) +- +- The 3c90x cards, according to the 3Com documentation, accept the +- following flash memory chips capacities: +- +- 64 kb (8 kB) +- 128 kb (16 kB) +- 256 kb (32 kB) and +- 512 kb (64 kB) +- +- Atmel AT29C512 (64 kilobyte) chips are specifically listed for both +- adapters, but flashing on the 3c905b cards would only be supported +- through the Atmel parts. Any device, of the supported size, should +- be supported when programmed by a dedicated PROM programmer (e.g. +- not the card). +- +- To use this driver in such a PROM, visit Atmel's web site and download +- their .PDF file containing a list of their distributors. Contact the +- distributors for pricing information. The prices are quite reasonable +- (about $3 US each for the 64 kB part), and are comparable to what one would +- expect for similarly sized standard EPROMs. And, the flash chips are much +- easier to work with, as they don't need to be UV-erased to be reprogrammed. +- The 3C905B card actually provides a method to program the flash memory +- while it is resident on board the card itself; if someone would like to +- write a small DOS program to do the programming, I can provide the +- information about the registers and so forth. +- +- A utility program, 3c90xutil, is provided with Etherboot in the 'contrib' +- directory that allows for the on-board flashing of the ROM while Linux +- is running. The program has been successfully used under Linux, but I +- have heard problem reports of its use under FreeBSD. Anyone willing to +- make it work under FreeBSD is more than welcome to do so! +- +- You also have the option of using EPROM chips - the 3C905B-TX-NM has been +- successfully tested with 27C256 (32kB) and 27C512 (64kB) chips with a +- specified access time of 100ns and faster. +- +- +-III GENERAL USE +- +- Normally, the basic procedure for using this driver is as follows: +- +- 1. Run the 3c90xcfg program on the driver diskette to enable the +- boot PROM and set it to 64k or 128k, as appropriate. +- 2. Build the appropriate 3c90x.fd0 or 3c90x.fd0 floppy image with +- possibly the value CFG_3C90X_XCVR defined to the transceiver type that +- you want to use (i.e., 10/100 rj45, AUI, coax, MII). +- 3. Run the floppy image on the PC to be network booted, to get +- it configured, and to verify that it will boot properly. +- 4. Build the 3c90x.rom or 3c90x.lzrom PROM image and program +- it into the flash or EPROM memory chip. +- 5. Put the PROM in the ethernet card, boot and enable 'boot from +- network first' in the system BIOS, save and reboot. +- +- Here are some issues to be aware of: +- +- 1. If you experience crashes or different behaviour when using the +- boot PROM, add the setting CFG_3C90X_BOOTROM_FIX and go through the +- steps 2-5 above. This works around a bug in some 3c905B cards (see +- below), but has some side-effects which may not be desirable. +- Please note that you have to boot off a floppy (not PROM!) once for +- this fix to take effect. +- 2. The possible need to manually set the CFG_3C90X_XCVR value to +- configure the transceiver type. Values are listed below. +- 3. The possible need to define CFG_3C90X_PRESERVE_XCVR for use in +- operating systems that don't intelligently determine the +- transceiver type. +- +- Some things that are on the 'To-Do' list, perhaps for me, but perhaps +- for any other volunteers out there: +- +- 1. Extend the driver to fully implement the auto-select +- algorithm if the card has multiple media ports. +- 2. Fix any bugs in the code <grin>.... +- 3. Extend the driver to support the 3c905c revision cards +- "officially". Right now, the support has been primarily empirical +- and not based on 3c905C documentation. +- +- Now for the details.... +- +- This driver has been tested on roughly 300 systems. The main two +- configuration issues to contend with are: +- +- 1. Ensure that PCI Busmastering is enabled for the adapter (configured +- in the CMOS setup) +- 2. Some systems don't work properly with the adapter when plug and +- play OS is enabled; I always set it to "No" or "Disabled" -- this makes +- it easier and really doesn't adversely affect anything. +- +- Roughly 95% of the systems worked when configured properly. A few +- have issues with booting locally once the boot PROM has been installed +- (this number has been less than 2%). Other configuration issues that +- to check: +- +- 1. Newer BIOS's actually work correctly with the network boot order. +- Set the network adapter first. Most older BIOS's automatically go to +- the network boot PROM first. +- 2. For systems where the adapter was already installed and is just +- having the PROM installed, try setting the "reset configuration data" +- to yes in the CMOS setup if the BIOS isn't seen at first. If your BIOS +- doesn't have this option, remove the card, start the system, shut down, +- install the card and restart (or switch to a different PCI slot). +- 3. Make sure the CMOS security settings aren't preventing a boot. +- +- The 3c905B cards have a significant 'bug' that relates to the flash prom: +- unless the card is set internally to the MII transceiver, it will only +- read the first 8k of the PROM image. Don't ask why -- it seems really +- obscure, but it has to do with the way they mux'd the address lines +- from the PCI bus to the ROM. Unfortunately, most of us are not using +- MII transceivers, and even the .lzrom image ends up being just a little +- bit larger than 8k. Note that the workaround for this is disabled by +- default, because the Windows NT 4.0 driver does not like it (no packets +- are transmitted). +- +- So, the solution that I've used is to internally set the card's nvram +- configuration to use MII when it boots. The 3c905b driver does this +- automatically. This way, the 16k prom image can be loaded into memory, +- and then the 3c905b driver can set the temporary configuration of the +- card to an appropriate value, either configurable by the user or chosen +- by the driver. +- +- To enable the 3c905B bugfix, which is necessary for these cards when +- booting from the Flash ROM, define -DCFG_3C90X_BOOTROM_FIX when building, +- create a floppy image and boot it once. +- Thereafter, the card should accept the larger prom image. +- +- The driver should choose an appropriate transceiver on the card. However, +- if it doesn't on your card or if you need to, for instance, set your +- card to 10mbps when connected to an unmanaged 10/100 hub, you can specify +- which transceiver you want to use. To do this, build the 3c905b.fd0 +- image with -DCFG_3C90X_XCVR=x, where 'x' is one of the following +- values: +- +- 0 10Base-T +- 1 10mbps AUI +- 3 10Base-2 (thinnet/coax) +- 4 100Base-TX +- 5 100Base-FX +- 6 MII +- 8 Auto-negotiation 10Base-T / 100Base-TX (usually the default) +- 9 MII External MAC Mode +- 255 Allow driver to choose an 'appropriate' media port. +- +- Then proceed from step 2 in the above 'general use' instructions. The +- .rom image can be built with CFG_3C90X_XCVR set to a value, but you +- normally don't want to do this, since it is easier to change the +- transceiver type by rebuilding a new floppy, changing the BIOS to floppy +- boot, booting, and then changing the BIOS back to network boot. If +- CFG_3C90X_XCVR is not set in a particular build, it just uses the +- current configuration (either its 'best guess' or whatever the stored +- CFG_3C90X_XCVR value was from the last time it was set). +- +- [[ Note for the more technically inclined: The CFG_3C90X_XCVR value is +- programmed into a register in the card's NVRAM that was reserved for +- LanWorks PROM images to use. When the driver boots, the card comes +- up in MII mode, and the driver checks the LanWorks register to find +- out if the user specified a transceiver type. If it finds that +- information, it uses that, otherwise it picks a transceiver that the +- card has based on the 3c905b's MediaOptions register. This driver isn't +- quite smart enough to always determine which media port is actually +- _connected_; maybe someone else would like to take on that task (it +- actually involves sending a self-directed packet and seeing if it +- comes back. IF it does, that port is connected). ]] +- +- Another issue to keep in mind is that it is possible that some OS'es +- might not be happy with the way I've handled the PROM-image hack with +- setting MII mode on bootup. Linux 2.0.35 does not have this problem. +- Behavior of other systems may vary. The 3com documentation specifically +- says that, at least with the card that I have, the device driver in the +- OS should auto-select the media port, so other drivers should work fine +- with this 'hack'. However, if yours doesn't seem to, you can try defining +- CFG_3C90X_PRESERVE_XCVR when building to cause Etherboot to keep the +- working setting (that allowed the bootp/tftp process) across the eth_reset +- operation. +- +- +-IV FOR DEVELOPERS.... +- +- If you would like to fix/extend/etc. this driver, feel free to do so; just +- be sure you can test the modified version on the 3c905B-TX cards that the +- driver was originally designed for. This section of this document gives +- some information that might be relevant to a programmer. +- +- A. Main Entry Point +- +- a3c90x_probe is the main entry point for this driver. It is referred +- to in an array in 'config.c'. +- +- B. Other Important Functions +- +- The functions a3c90x_transmit, a3c90x_poll, a3c90x_reset, and +- a3c90x_disable are static functions that EtherBoot finds out about +- as a result of a3c90x_probe setting entries in the nic structure +- for them. The EtherBoot framework does not use interrupts. It is +- polled. All transmit and receive operations are initiated by the +- etherboot framework, not by an interrupt or by the driver. +- +- C. Internal Functions +- +- The following functions are internal to the driver: +- +- a3c90x_internal_IssueCommand - sends a command to the 3c905b card. +- a3c90x_internal_SetWindow - shifts between one of eight register +- windows onboard the 3c90x. The bottom 16 bytes of the card's +- I/O space are multiplexed among 128 bytes, only 16 of which are +- visible at any one time. This SetWindow function selects one of +- the eight sets. +- a3c90x_internal_ReadEeprom - reads a word (16 bits) from the +- card's onboard nvram. This is NOT the BIOS boot rom. This is +- where the card stores such things as its hardware address. +- a3c90x_internal_WriteEeprom - writes a word (16 bits) to the +- card's nvram, and recomputes the eeprom checksum. +- a3c90x_internal_WriteEepromWord - writes a word (16 bits) to the +- card's nvram. Used by the above routine. +- a3c90x_internal_WriteEepromWord - writes a word (16 bits) to the +- card's nvram. Used by the above routine. +- +- D. Globals +- +- All global variables are inside a global structure named INF_3C90X. +- So, wherever you see that structure referenced, you know the variable +- is a global. Just keeps things a little neater. +- +- E. Enumerations +- +- There are quite a few enumerated type definitions for registers and +- so forth, many for registers that I didn't even touch in the driver. +- Register types start with 'reg', window numbers (for SetWindow) +- start with 'win', and commands (for IssueCommand) start with 'cmd'. +- Register offsets also include an indication in the name as to the +- size of the register (_b = byte, _w = word, _l = long), and which +- window the register is in, if it is windowed (0-7). +- +- F. Why the 'a3c90x' name? +- +- I had to come up with a letter at the beginning of all of the +- identifiers, since 3com so conveniently had their name start with a +- number. Another driver used 't' (for 'three'?); I chose 'a' for +- no reason at all. +- +-Addendum by Jorge L. deLyra <delyra@latt.if.usp.br>, 22Nov2000 re +-working around the 3C905 hardware bug mentioned above: +- +-Use this floppy to fix any 3COM model 3C905B PCI 10/100 Ethernet cards +-that fail to load and run the boot program the first time around. If +-they have a "Lucent" rather than a "Broadcom" chipset these cards have +-a configuration bug that causes a hang when trying to load the boot +-program from the PROM, if you try to use them right out of the box. +- +-The boot program in this floppy is the file named 3c905b-tpo100.rom +-from Etherboot version 4.6.10, compiled with the bugfix parameter +- +- CFG_3C90X_BOOTROM_FIX +- +-You have to take the chip off the card and boot the system once using +-this floppy. Once loaded from the floppy, the boot program will access +-the card and change some setting in it, correcting the problem. After +-that you may use either this boot program or the normal one, compiled +-without this bugfix parameter, to boot the machine from the PROM chip. +- +-[Any recent Etherboot version should do, not

V0.4 is a complete re-write with only the kernel interface +- remaining from the original code. +- +- 1) Lance.c code in /linux/drivers/net/ +- 2) "Ethernet/IEEE 802.3 Family. 1992 World Network Data Book/Handbook", +- AMD, 1992 [(800) 222-9323]. +- 3) "Am79C90 CMOS Local Area Network Controller for Ethernet (C-LANCE)", +- AMD, Pub. #17881, May 1993. +- 4) "Am79C960 PCnet-ISA(tm), Single-Chip Ethernet Controller for ISA", +- AMD, Pub. #16907, May 1992 +- 5) "DEC EtherWORKS LC Ethernet Controller Owners Manual", +- Digital Equipment corporation, 1990, Pub. #EK-DE100-OM.003 +- 6) "DEC EtherWORKS Turbo Ethernet Controller Owners Manual", +- Digital Equipment corporation, 1990, Pub. #EK-DE200-OM.003 +- 7) "DEPCA Hardware Reference Manual", Pub. #EK-DEPCA-PR +- Digital Equipment Corporation, 1989 +- 8) "DEC EtherWORKS Turbo_(TP BNC) Ethernet Controller Owners Manual", +- Digital Equipment corporation, 1991, Pub. #EK-DE202-OM.001 +- +- +- Peter Bauer's depca.c (V0.5) was referred to when debugging V0.1 of this +- driver. +- +- The original DEPCA card requires that the ethernet ROM address counter +- be enabled to count and has an 8 bit NICSR. The ROM counter enabling is +- only done when a 0x08 is read as the first address octet (to minimise +- the chances of writing over some other hardware's I/O register). The +- NICSR accesses have been changed to byte accesses for all the cards +- supported by this driver, since there is only one useful bit in the MSB +- (remote boot timeout) and it is not used. Also, there is a maximum of +- only 48kB network RAM for this card. My thanks to Torbjorn Lindh for +- help debugging all this (and holding my feet to the fire until I got it +- right). +- +- The DE200 series boards have on-board 64kB RAM for use as a shared +- memory network buffer. Only the DE100 cards make use of a 2kB buffer +- mode which has not been implemented in this driver (only the 32kB and +- 64kB modes are supported [16kB/48kB for the original DEPCA]). +- +- At the most only 2 DEPCA cards can be supported on the ISA bus because +- there is only provision for two I/O base addresses on each card (0x300 +- and 0x200). The I/O address is detected by searching for a byte sequence +- in the Ethernet station address PROM at the expected I/O address for the +- Ethernet PROM. The shared memory base address is 'autoprobed' by +- looking for the self test PROM and detecting the card name. When a +- second DEPCA is detected, information is placed in the base_addr +- variable of the next device structure (which is created if necessary), +- thus enabling ethif_probe initialization for the device. More than 2 +- EISA cards can be supported, but care will be needed assigning the +- shared memory to ensure that each slot has the correct IRQ, I/O address +- and shared memory address assigned. +- +- ************************************************************************ +- +- NOTE: If you are using two ISA DEPCAs, it is important that you assign +- the base memory addresses correctly. The driver autoprobes I/O 0x300 +- then 0x200. The base memory address for the first device must be less +- than that of the second so that the auto probe will correctly assign the +- I/O and memory addresses on the same card. I can't think of a way to do +- this unambiguously at the moment, since there is nothing on the cards to +- tie I/O and memory information together. +- +- I am unable to test 2 cards together for now, so this code is +- unchecked. All reports, good or bad, are welcome. +- +- ************************************************************************ +- +- The board IRQ setting must be at an unused IRQ which is auto-probed +- using Donald Becker's autoprobe routines. DEPCA and DE100 board IRQs are +- {2,3,4,5,7}, whereas the DE200 is at {5,9,10,11,15}. Note that IRQ2 is +- really IRQ9 in machines with 16 IRQ lines. +- +- No 16MB memory limitation should exist with this driver as DMA is not +- used and the common memory area is in low memory on the network card (my +- current system has 20MB and I've not had problems yet). +- +- The ability to load this driver as a loadable module has been added. To +- utilise this ability, you have to do <8 things: +- +- 0) have a copy of the loadable modules code installed on your system. +- 1) copy depca.c from the /linux/drivers/net directory to your favourite +- temporary directory. +- 2) if you wish, edit the source code near line 1530 to reflect the I/O +- address and IRQ you're using (see also 5). +- 3) compile depca.c, but include -DMODULE in the command line to ensure +- that the correct bits are compiled (see end of source code). +- 4) if you are wanting to add a new card, goto 5. Otherwise, recompile a +- kernel with the depca configuration turned off and reboot. +- 5) insmod depca.o [irq=7] [io=0x200] [mem=0xd0000] [adapter_name=DE100] +- [Alan Cox: Changed the code to allow command line irq/io assignments] +- [Dave Davies: Changed the code to allow command line mem/name +- assignments] +- 6) run the net startup bits for your eth?? interface manually +- (usually /etc/rc.inet[12] at boot time). +- 7) enjoy! +- +- Note that autoprobing is not allowed in loadable modules - the system is +- already up and running and you're messing with interrupts. +- +- To unload a module, turn off the associated interface +- 'ifconfig eth?? down' then 'rmmod depca'. +- +- To assign a base memory address for the shared memory when running as a +- loadable module, see 5 above. To include the adapter name (if you have +- no PROM but know the card name) also see 5 above. Note that this last +- option will not work with kernel built-in depca's. +- +- The shared memory assignment for a loadable module makes sense to avoid +- the 'memory autoprobe' picking the wrong shared memory (for the case of +- 2 depca's in a PC). +- +- ************************************************************************ +- Support for MCA EtherWORKS cards added 11-3-98. +- Verified to work with up to 2 DE212 cards in a system (although not +- fully stress-tested). +- +- Currently known bugs/limitations: +- +- Note: with the MCA stuff as a module, it trusts the MCA configuration, +- not the command line for IRQ and memory address. You can +- specify them if you want, but it will throw your values out. +- You still have to pass the IO address it was configured as +- though. +- +- ************************************************************************ +- TO DO: +- ------ +- +- +- Revision History +- ---------------- +- +- Version Date Description +- +- 0.1 25-jan-94 Initial writing. +- 0.2 27-jan-94 Added LANCE TX hardware buffer chaining. +- 0.3 1-feb-94 Added multiple DEPCA support. +- 0.31 4-feb-94 Added DE202 recognition. +- 0.32 19-feb-94 Tidy up.

See the revision +-history in the tulip.c file for information on changes. This version +-of the driver incorporates changes from Bob Edwards and Paul Mackerras +-who cantributed changes to support the TRENDnet TE100-PCIA NIC which +-uses a genuine Intel 21143-PD chipset. There are also various code +-cleanups to make time-based activities more reliable. +- +-Of course you have to have all the usual Etherboot environment +-(bootp/dhcp/NFS) set up, and you need a Linux kernel with v0.91g +-(7.16.99) or later of the tulip.c driver compiled in to support some +-MX98715 based cards. That file is available at: +- +- http://cesdis.gsfc.nasa.gov/linux/drivers/test/tulip.c +- +-NOTES +- +-I've tested this driver with a SOHOware Fast 10/100 Model SDA110A, +-a Linksys LNE100TX v2.0, and a Netgear FA310TX card, and it worked at +-both 10 and 100 mbits. Other cards based on the tulip family may work as +-well. +- +-These cards are about 20$US, are supported by Linux and now Etherboot, +-and being PCI, they auto-configure IRQ and IOADDR and auto-negotiate +-10/100 half/full duplex. It seems like a pretty good value compared to +-some of the pricier cards, and can lower the cost of building/adapting +-thin client workstations substantially while giving a considerable +-performance increase. +- +-On some PCI tulip clone chipsets (MX987x5, LC82C115, LC82C168) this driver +-lets the card choose the fastest speed it can negotiate with the peer +-device. On other cards, it chooses 10mbit half-duplex. +- +-I burned an AM27C256 (32KByte) EPROM with mx987x5.lzrom and it worked. +-According to the data sheet the MX98715A supports up to 64K (27C512) +-EPROMs, +- +-I've liberally commented the code and header files in the hope that it +-will help the next person who hacks the code or needs to support some +-tulip clone card, or wishes to add functionality. +- +-Anyway, please test this if you can on your tulip based card, and let +-me (mdc@thinguin.org) and the netboot list (netboot@baghira.han.de) +-know how things go. I also would appreciate code review by people who +-program.
