1The EtherWORKS 3 driver in this distribution is designed to work with all
2kernels > 1.1.33 (approx) and includes tools in the 'ewrk3tools'
3subdirectory to allow set up of the card, similar to the MSDOS
4'NICSETUP.EXE' tools provided on the DOS drivers disk (type 'make' in that
5subdirectory to make the tools).
6
7The supported cards are DE203, DE204 and DE205. All other cards are NOT
8supported - refer to 'depca.c' for running the LANCE based network cards and
9'de4x5.c' for the DIGITAL Semiconductor PCI chip based adapters from
10Digital.
11
12The ability to load this driver as a loadable module has been included and
13used extensively during the driver development (to save those long reboot
14sequences). To utilise this ability, you have to do 8 things:
15
16    0) have a copy of the loadable modules code installed on your system.
17    1) copy ewrk3.c from the /linux/drivers/net directory to your favourite
18    temporary directory.
19    2) edit the source code near line 1898 to reflect the I/O address and
20    IRQ you're using.
21    3) compile ewrk3.c, but include -DMODULE in the command line to ensure
22    that the correct bits are compiled (see end of source code).
23    4) if you are wanting to add a new card, goto 5. Otherwise, recompile a
24    kernel with the ewrk3 configuration turned off and reboot.
25    5) insmod ewrk3.o
26          [Alan Cox: Changed this so you can insmod ewrk3.o irq=x io=y]
27          [Adam Kropelin: Multiple cards now supported by irq=x1,x2 io=y1,y2]
28    6) run the net startup bits for your new eth?? interface manually
29    (usually /etc/rc.inet[12] at boot time).
30    7) enjoy!
31
32    Note that autoprobing is not allowed in loadable modules - the system is
33    already up and running and you're messing with interrupts.
34
35    To unload a module, turn off the associated interface
36    'ifconfig eth?? down' then 'rmmod ewrk3'.
37
38The performance we've achieved so far has been measured through the 'ttcp'
39tool at 975kB/s. This measures the total TCP stack performance which
40includes the card, so don't expect to get much nearer the 1.25MB/s
41theoretical Ethernet rate.

43
44Enjoy!
