I’m no expert by far but all PNP devices are enumerated
by bus drivers. If your card has no ISA PNP functionality
then the ISA PNP bus won’t enumerate it. Therefore you
can’t write a wdm driver for it. You would have to write
regular drivers for it.
In order to use the device at all you would have to reserve
an irq in the perticular computers BIOS setup so that the
required irq isn’t allocated to a pnp device.
I’m writing a driver for a old style ISA card which has no PnP
functionality for use on Win98/W2k.
As I understand the WDM, the PnP manager calls the
StartDevice function
of the driver with the needed recourcelist as parameter.
The PnP manager now about recourse of a device when this
device is PCI
or ISA-PnP, but what to do, if its none of them?
My old style ISA card uses 2 Interrupts (IRQ 10/11) and some ports
beginning from 0x300.
How can I tell the PnP Manager to call my StartDevice
function with that
parameter?
Is there a way to define this settings through the drivers
INF file, or
have I to add some registry keys which the PnP Manager will
read before
calling StartDevice?
