I have changed my INF file to have LogConfigOverride
section with resources specified. But still I haven’t
got call to hwFindAdapter. Pls let me know if any
changes reqd.
[*Servide_inst.LogConfigOverride]
ConfigPriority = HARDRECONFIG
IOConfig =
130-133(3FF::),230-233(3FF::),330-333(3FF::),134-137(3FF::),234-237(3FF::),334-337(3FF:
IRQConfig = 9,10,11,12,14,15
My Driver entry looks like below:
HW_INITIALIZATION_DATA hwInitializationData;
ULONG Status;
UCHAR VendorId[4] = {
‘8’, ‘0’, ‘8’, ‘6’ };
UCHAR DeviceId[4] = {
‘1’, ‘0’, ‘5’, ‘E’ };
ON_INIT(DbgPrint(“==>Entering DriverEntry,
DriverObj=0x%p\n”,DriverObject)
_asm int 3;
BreakPoint();
pDriverObject = DriverObject;
///////////////////////////////////
