@ -21,6 +21,8 @@ New in 0.5.95 - XXXX-XX-XX:
"grub-install" has the same effect as to the command "install".
* The configure script doesn't accept the option
`--disable-lba-support-bitmap-check' any longer. Use the option above.
* The network support is updated to Etherboot-4.5.8. So now we have
3Com59x and DEPCA drivers.
New in 0.5.94 - 2000-03-06:
* Stage 1 supports both the LBA mode and the CHS mode.

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

it is resident on board the card itself; if someone would like to write a

Better yet, for those using Linux it might be even better if the programming
could be done while Linux is running, either via a modification to the 3c59x
driver or via some other program/driver. That way, a system administrator
on a private network could update all the NC flash images from a centrally
managed location.
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!
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. Edit Config (in the src-32 directory) and define the
90X_SIGNATURE for your particular adapter (model numbers and
corresponding values are listed in the file)
3. Build the 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, etc.)
4. Run the floppy image on the PC to be network booted, to get
it configured, and to verify that it will boot properly.
5. Build the 3c90x.rom or 3c90x.lzrom PROM image and program
it into the flash memory chip.
6. Put the PROM in the ethernet card, boot and enable 'boot from
network first' in the system BIOS, save and reboot.
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 verify that
it will boot properly.
4. Build the 3c90x.rom or 3c90x.lzrom PROM image and program
it into the flash 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. A picky BIOS that may work better with NO_PNP_PCI_HEADER
defined to boot the prom image.
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.
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.

3. The possible need to define CFG_3C90X_PRESERVE_XCVR for use in

transceiver type.
Some things that are on the 'To-Do' list, perhaps for me, but perhaps
for any other volunteers out there:
1. Write a DOS- or Linux- based flash programmer for the 3c905b
card, so PROM users don't have to buy a $200 programmer....
2. Extend the driver to fully implement the auto-select
algorithm if the card has multiple media ports.
3. Fix any bugs in the code <grin>....
4. Extend the driver to support the 3c905c revision cards
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.

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).

no reason at all.

/* depca.c: A DIGITAL DEPCA & EtherWORKS ethernet driver for linux.

This software may be used and distributed according to the terms of

This driver is written for the Digital Equipment Corporation series
of DEPCA and EtherWORKS ethernet cards:
DEPCA (the original)
DE100
DE101
DE200 Turbo
DE201 Turbo
DE202 Turbo (TP BNC)
DE210
DE422 (EISA)
The driver has been tested on DE100, DE200 and DE202 cards in a
relatively busy network. The DE422 has been tested a little.
This driver will NOT work for the DE203, DE204 and DE205 series of
cards, since they have a new custom ASIC in place of the AMD LANCE
chip. See the 'ewrk3.c' driver in the Linux source tree for running
those cards.
I have benchmarked the driver with a DE100 at 595kB/s to (542kB/s from)
a DECstation 5000/200.
The author may be reached at davies@maniac.ultranet.com
=========================================================================
The driver was originally based on the 'lance.c' driver from Donald
Becker which is included with the standard driver distribution for
linux. V0.4 is a complete re-write with only the kernel interface
remaining from the original code.

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.

Tulip and clone Etherboot Driver
By Marty Connor (mdc@thinguin.org)
This software may be used and distributed according to the terms
of the GNU Public License, incorporated herein by reference.
Based on Ken Yap's Tulip Etherboot Driver and Donald Becker's
Linux Tulip Driver. Supports N-Way speed auto-configuration on
MX98715, MX98715A and MX98725. Support inexpensive PCI 10/100 cards
based on the Macronix MX987x5 chip, such as the SOHOware Fast
model SFA110A, and the LinkSYS model LNE100TX. The NetGear
model FA310X, based on the LC82C168 chip is also supported.
Documentation and source code used:

MX98715A Data Sheet and MX98715A Application Note
on http://www.macronix.com/ (PDF format files)
Source for Linux tulip driver at

Adapted by Ken Yap from
FreeBSD netboot DEC 21143 driver
Author: David Sharp
date: Nov/98
Some code fragments were taken from verious places, Ken Yap's
etherboot, FreeBSD's if_de.c, and various Linux related files.
DEC's manuals for the 21143 and SROM format were very helpful.
The Linux de driver development page has a number of links to
useful related information. Have a look at:

*/
/*********************************************************************/
/* Revision History */
/*********************************************************************/
/*
11 Jan 2000 mdc 0.75b4
Added support for NetGear FA310TX card based on the LC82C168
chip. This should also support Lite-On LC82C168 boards.
Added simple MII support. Re-arranged code to better modularize
initializations.
04 Dec 1999 mdc 0.75b3
Added preliminary support for LNE100TX PCI cards. Should work for
PNIC2 cards. No MII support, but single interface (RJ45) tulip
cards seem to not care.
03 Dec 1999 mdc 0.75b2
Renamed from mx987x5 to ntulip, merged in original tulip init code
from tulip.c to support other tulip compatible cards.
02 Dec 1999 mdc 0.75b1
Released Beta MX987x5 Driver for code review and testing to netboot
and thinguin mailing lists.

Etherboot DEC Tulip driver
adapted by Ken Yap from
FreeBSD netboot DEC 21143 driver
Author: David Sharp
date: Nov/98
Known to work on DEC DE500 using 21143-PC chipset.
Even on cards with the same chipset there can be
incompatablity problems with the way media selection
and status LED settings are done. See comments below.
Some code fragments were taken from verious places,
Ken Yap's etherboot, FreeBSD's if_de.c, and various
Linux related files. DEC's manuals for the 21143 and
SROM format were very helpful. The Linux de driver
development page has a number of links to useful
related information. Have a look at:
ftp://cesdis.gsfc.nasa.gov/pub/linux/drivers/tulip-devel.html

Tulip and clone Etherboot Driver
By Marty Connor (mdc@thinguin.org)
This software may be used and distributed according to the terms
of the GNU Public License, incorporated herein by reference.
FreeBSD netboot DEC 21143 driver
Based on Ken Yap's Tulip Etherboot Driver and Donald Becker's
Linux Tulip Driver. Supports N-Way speed auto-configuration on
MX98715, MX98715A and MX98725. Support inexpensive PCI 10/100 cards
based on the Macronix MX987x5 chip, such as the SOHOware Fast
model SFA110A, and the LinkSYS model LNE100TX. The NetGear
model FA310X, based on the LC82C168 chip is supported.
The TRENDnet TE100-PCIA NIC which uses a genuine Intel 21143-PD
chipset is supported.

Known to work on DEC DE500 using 21143-PC chipset.
Even on cards with the same chipset there can be
incompatablity problems with the way media selection
and status LED settings are done. See comments below.
Some code fragments were taken from verious places,
Ken Yap's etherboot, FreeBSD's if_de.c, and various
Linux related files. DEC's manuals for the 21143 and
SROM format were very helpful. The Linux de driver
development page has a number of links to useful
related information. Have a look at:

/*********************************************************************/
/* Revision History */
/*********************************************************************/
/*
29 Feb 2000 mdc 0.75b7
Increased reset delay to 3 seconds because Macronix cards seem to
need more reset time before card comes back to a usable state.
26 Feb 2000 mdc 0.75b6
Added a 1 second delay after initializing the transmitter because
some cards seem to need the time or they drop the first packet
transmitted.
23 Feb 2000 mdc 0.75b5
removed udelay code and used currticks() for more reliable delay
code in reset pause and sanity timeouts. Added function prototypes
and TX debugging code.
21 Feb 2000 mdc patch to Etherboot 4.4.3
Incorporated patches from Bob Edwards and Paul Mackerras of
Linuxcare's OZLabs to deal with inefficiencies in tulip_transmit
and udelay. We now wait for packet transmission to complete
(or sanity timeout).
04 Feb 2000 Robert.Edwards@anu.edu.au patch to Etherboot 4.4.2
patch to tulip.c that implements the automatic selection of the MII
interface on cards using the Intel/DEC 21143 reference design, in
particular, the TRENDnet TE100-PCIA NIC which uses a genuine Intel
21143-PD chipset.
11 Jan 2000 mdc 0.75b4
Added support for NetGear FA310TX card based on the LC82C168
chip. This should also support Lite-On LC82C168 boards.
Added simple MII support. Re-arranged code to better modularize
initializations.
04 Dec 1999 mdc 0.75b3
Added preliminary support for LNE100TX PCI cards. Should work for
PNIC2 cards. No MII support, but single interface (RJ45) tulip
cards seem to not care.
03 Dec 1999 mdc 0.75b2
Renamed from mx987x5 to tulip, merged in original tulip init code
from tulip.c to support other tulip compatible cards.
02 Dec 1999 mdc 0.75b1
Released Beta MX987x5 Driver for code review and testing to netboot
and thinguin mailing lists.
