display mirror driver for 2000

OSR_Community_UserOSR_Community_User Member Posts: 110,217
Hi all,

I am developing display mirror driver for 2000. Now I want to load the built
drivers. I have loaded miniport driver using OSRLoader. Now control comes to
DriverEntry routine and VideoPortInitialize returns NULL. But when I say MOD
command in softIce it does not show module name.

Can anybody tell me, where I am going wrong?

What exactly VideoPortInitialize should return?
And if possible how to load display driver( .dll file )?

Has anybody worked in mirror display driver?
There is not much documentation available on mirror driver in NTDDK also..

Many Thanks,
Giri

    Use the ddmlapp.exe app to install the mirror driver. That should take care
    of everything. It works fine if you follow the instructions in the README
    (mirror\app directory). I haven't had any problems loading the driver etc.

    ATB,

    -A!
