Here are a few more adventures with PCMCIA cards:

1. Controll your sockets! 

When wanted to do some more tests with the wifi-card on the Pentium
III, I lost nearly an hour due to the fact, that I inserted the card
into the second socket instead of the first. 

2. IRQ numbers 

But this experience was a good preparation for the following: 
If a packet driver loads into memory, that does not mean that 
it will work. Even hopeful blinking means nothing ;-)

Without reason I changed the IRQ number from 10 to 11. And suddenly 
even on this machine all Wattcp.cfg problems evaporized. 

3. Memory address

An unknown amount of problems may have their origin in wrong 
memory specification. 

It is cleat that the command line paramaters of the PCMCIA enable 
must to correspond to the excluded area in EMM386.EXE, eg.

    DEVICE=C:\DOS\DOS\EMM386.EXE X=DE00-DFFF NOEMS
    ...
    DEVICEHIGH=C:\DOS\CONNECT\PKTDRV\AVAYA\WVLANCAD.SYS 
        /i=11 /b=300 /m=de00

But: 

   - This memory seems also to be used by other drivers. 
     Certainly by USB drivers, but presumably not only by
     them. 
     
   - How will I know, how much memory the packet driver will 
     need. DF00-DFFF failed on this machine, DE00-DFFF seems
     to work.
