NT NDIS problem in NdisRegisterIoPortRange

Hallo, people

I´m new in this list.
I´m developing in my work a NT4.0 NDIS miniport driver for
a ISA card. In the last week I studied and create a setup (INF)
file specific to my driver that I believe is Ok. I can write
information in the NT registry using my INF file and read it
from my driver.
Unfortunately I´m having problems, when I try to registry
the driver´s I/O Port address in the NDIS library. I call
NdisMSetAttributes before call NdisMRegisterIoPortRange, like
is indicated in the DDK document, but I always receive
NDIS_STATUS_FAILURE as response.
I make a lot of tests but until now I couldn´t solve
this initial problem. It´s very strange.
Someone here have already developed a NDIS NT driver to
a ISA card or have similar problems in the first implementation?
Any information about this could be useful.
Thanks in advance,

Ronaldo Husemann

This is OK.

You using the rigth bus type in NdisMSetAttribute(Ex) ?
(Must be the same in INF file)

Ok, I know this is bad question … You are shure you
IoAddress and range are free ?

Yes I got the information from NT registry and printed it.
It?s really NdisInterfaceIsa…

Not totally sure, because this problem is very strange
and I?m doubting about everything. :slight_smile:
I read information from NT Diagnosys and in the field
Resouces - IOport this area isn?t appear. Looks like no
device is occuping it then it?s free.
