My computer, like most, has 2 serial ports. I want to disable Windows from
using this hardware. More accurately, I want my NDIS driver to use this
hardware. I want to assign address range 0x2f8-0x2ff and IRQ3 to my NDIS
miniport driver, and not to COM2. But nothing I do seems to get Windows to
release these resources, and thus, there is a conflict with my device.
I’ve tried modifying serial.sys and serenum.sys so that they fail in
DriverEntry, (DriverManager still showed these resources belonging to
COM2). I tried removing these files, (On re-boot, the files were
restored).
What does it take to tell Windows that this hardware is not a serial port,
but is in-fact my NDIS driver?
Are there some registry settings I have to delete?
Any help is appreciated.
Thanks,
Brian

Can UpdateDriverForPlugAndPlayDevices destroy the serial’s INF file and install the Brian’s driver’s INF file instead as a FD for
serial ports?

When you change any known windows drivers with your own version, make it with safe boot
option. I mean your changes never used from the system.
Other try, search for the given serial inf file in \windows\inf and
delete it. I hope the serenum.sys is unloaded too.
Now remove the drivers with device manager.
