ndiscvt question

[ticket at knightowls.dyndns.org]

I am new to freebsd. I have loaded 5.3 on an old IBM thinkpad type
2611-410 with 32mb of ram. Runs just fine. I am trying to bring up an
cisco pcm352 wireless interface, but the system doesn't recognize it. I
get "pccard0 init failed" on insertion. I am trying to use ndiscvt to
create a loadable module for it. I obtained the .sys and .inf files for
the cisco card.

I run:
ndiscvt -i netX500.inf -s pcx500.sys -o ndis_driver_data.h

I get the following error:
ndiscvt: line 456: 100-3FF: syntax error.

this is line 456 from the inf file:
IOConfig=40 at 100-3FF(3FF::)

has anyone encountered this?
Can someone that has done this successfully post the IOConfig line from
your .inf file so I can see the correct syntax.

I am new to freebsd, I have a background of solaris and sunos way back
when.....
