Re: PC/104 PCMCIA configuration problem

Hello Doug,

many many thanks for your help.
Fortunately i can now (it works since just 3 minutes) confirm that the
MIP520 / PCMCIA-1 combination works. There's a BIOS entry "memwin and
memwin-base" that i disabled (because i didn't know what it meant, and
it's disabled in the "safe factory settings")
Now that i enabled it - everything works fine. i'm pretty happy - because
this was the missing piece for having WaveLAN connectivity.

regards and thanks
 ralf
