1 The EtherWORKS 3 driver in this distribution is designed to work with all
2 kernels > 1.1.33 (approx) and includes tools in the 'ewrk3tools'
3 subdirectory 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
5 subdirectory to make the tools).
6
7 The supported cards are DE203, DE204 and DE205. All other cards are NOT
8 supported - refer to 'depca.c' for running the LANCE based network cards and
9 'de4x5.c' for the DIGITAL Semiconductor PCI chip based adapters from
10 Digital.
11
12 The ability to load this driver as a loadable module has been included and
13 used extensively during the driver development (to save those long reboot
14 sequences). 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
38 The performance we've achieved so far has been measured through the 'ttcp'
39 tool at 975kB/s. This measures the total TCP stack performance which
40 includes the card, so don't expect to get much nearer the 1.25MB/s
41 theoretical Ethernet rate.
42
43
44 Enjoy!
