The problem is, your DDK sample driver may not have the code to handle
a Resource Information request. In this case, the device manager will not
be
able to display anything on its list for your sample driver. I can
explain why you see the listing for network driver, this is how it works: In
a network driver environment, the Device Manager will call
NdisMQueryAdapterResources() function, this functions is finally handled by
a miniport driver, it pulled information from the hardware and send the info
back to the caller (Device Manager) to be displayed. The Device manager
will display at its option simple or detailed information.

---------------------------------------------------------------------------------------------------------------------
a Device Manager will call this function:

NdisMQueryAdapterResources(&stat, WrapperConfigurationContext, resList,
&bufSize);

if (stat == NDIS_STATUS_SUCCESS){
PCM_PARTIAL_RESOURCE_DESCRIPTOR resDesc;
BOOLEAN haveIRQ = FALSE,
haveIOAddr = FALSE,
haveDma = FALSE;
UINT i;

for (resDesc = resList->PartialDescriptors, i = 0;
i < resList->Count;
resDesc++, i++){

switch (resDesc->Type){
case CmResourceTypePort:
if (thisDev->CardType==PC87108 &&
(resDesc->u.Port.Start.LowPart==0xEA ||
resDesc->u.Port.Start.LowPart==0x398 ||
resDesc->u.Port.Start.LowPart==0x150))
{
// This is an eval board and to config io base address

thisDev->portInfo.ConfigIoBasePhysAddr =
resDesc->u.Port.Start.LowPart;
}
else if (thisDev->CardType==PC87308 &&
(resDesc->u.Port.Start.LowPart==0x2E ||
resDesc->u.Port.Start.LowPart==0x15C))
{
// This is an eval board and to config io base address

thisDev->portInfo.ConfigIoBasePhysAddr =
resDesc->u.Port.Start.LowPart;
}
