  ChangeLog:

  Thu Dec 6 22:40:00 1996  Markus Gutschke  <gutschk@math.uni-muenster.de>

  * disabled all "advanced" features; this should make the code more reliable

  * reorganized the reset function

  * always reset the address port, so that autoprobing will continue working

  * some cosmetic changes

  * 2.5

  Thu Dec 5 21:00:00 1996  Markus Gutschke  <gutschk@math.uni-muenster.de>

  * tested the code against a CS8900 card

  * lots of minor bug fixes and adjustments

  * this is the first release, that actually works! it still requires some
    changes in order to be more tolerant to different environments

  * 4

  Fri Nov 22 23:00:00 1996  Markus Gutschke  <gutschk@math.uni-muenster.de>

  * read the manuals for the CS89x0 chipsets and took note of all the
    changes that will be neccessary in order to adapt Russel Nelson's code
    to the requirements of a BOOT-Prom

  * 6

  Thu Nov 19 22:00:00 1996  Markus Gutschke  <gutschk@math.uni-muenster.de>

  * Synched with Russel Nelson's current code (v1.00)

  * 2

  Thu Nov 12 18:00:00 1996  Markus Gutschke  <gutschk@math.uni-muenster.de>

  * Cleaned up some of the code and tried to optimize the code size.

  * 1.5

  Sun Nov 10 16:30:00 1996  Markus Gutschke  <gutschk@math.uni-muenster.de>

  * First experimental release. This code compiles fine, but I
  have no way of testing whether it actually works.

  * I did not (yet) bother to make the code 16bit aware, so for
  the time being, it will only work for Etherboot/32.

  * 12
