   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.

  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!
