Supported cards:
  Should: many of the DEC's DEPCA-family. However, I currently
  could only test the driver against a DE200 (Turbo etherlink)
  Together witch information received from others, it seems to
  work with  (25-Sep-93)
    DE200 64K
    DE200 32K
    DE202
    DE100
    DEPCA rev E
  (currently) NOT: any etherlink III devices.

  Since Rel. 0.5 it should also be possible to have more than
  one depca in a PC (since the cards only support io-bases
  0x200 and 0x300, the `more' actually says `up to 2'). They need to 
  have different irq's, base-addresses and iobases (and, of
  course, each needs an entry in Space.c (e.g de0 and de1)).

Base for installation:
  plain lx99pl14 (Release version)

Installation:

a. place the driver (its a diff containing all) into /usr/src 
   cp ... /usr/src/depca-0.8.tar.z
   cd /usr/src
   zcat depca-0.8.tar.z|tar xvf -
   results in depca-0.8.diffs and this file (README.DEPCA)
b. apply the patches contained in depca-0.8.diffs:
   patch -p0 <depca-0.8.diffs 2>&1 >depca.log
c. verify that depca.log contains no failed hunks
   you may want to remove README.DEPCA from /usr/src (because its duplicated 
   in /linux/net/inet)
d. Make sure your DEPCA matches the settings in Space.c (ETH0_BASE,
   ETH0_ADDR,ETH0_IRQ in the CONFIG_DEPCA - #ifdef section)
e. cd /linux
   make config
f. put formatted, erasable disk in /dev/fd0
g. goto /linux and make new system:
   cd /linux
   make zdisk
h. go to /conf/inet/rc.inet1 and change the adapter passed
   to ifconfig to eth0 (no longer de0 or anything else):
   ifconfig eth0 ...
i. reboot....
j. If the driver complains about rx timeouts, your box is to fast
   You need to modify the two SlowerOut?-routines in depca.c (add
   some loops...) The current ones work fine on my 386DX-40 
   If the driver doesn't detect your card, defining ANY_SIGNATURE
   in depca.c may help
k. If you ar forced to switch the depca-card down to 32K (due to other
   devices overlapping all of the switchable 64k-ranges of a depca)
   and use a faster box (486 25+), the driver will probably not work. 
   Please fix this bug and send the patch to me. 8->
l. If the driver reports "xmit full", you may want to comment out the
   according printk

Todo:
- Test against other DEPCA-boards
- The driver code could be optimized
- ...

If you suceed in using this driver, and your type of depca isn't yet
listed here, send me a mail
If you fail in using this driver, send me a mail. (or a patch :-)
