You see, the voltage is inverted but that has nothing to do with
your problem. The card is stuck at a middle initialization stage,
and is not working because it's irq=0, and not 106.
It is an interesting card if it really needs Vpp.
The right configuration (IMHO) should be:

My ne2000 card is
manfid:	0x8a01, 0x0100
and 
TDK modem (standard for the european j820E)
manfid:	0x0105, 0x3e0a

Both work.

The problems of Francois are of absulutely different nature, since his
card is at least properly configured:

 Oleg.

PS. I can send you the modified hpcboot that will monitor the
       changes of pcmcia control register PCCR, so we will know
       how wince configures your card.
