Memory Issues in developing 64 bit Driver in ?Windows 64 bit standard edition?

Hi All,

I?m developing a function driver 64bit, on ?Windows 64 bit Standard Edition?.
I encountered with two issues:

  1. Failed to pass pointer buffer (more then 16 Mb size) from 64 / 32 bit application
    To the 64 bit Driver (probe & lock mechanize fails).

  2. Failed to map in 64 bit Driver more then 1 Gb memory (using MmMapIoSpace api).

I will appreciate your assistance.

Thanks.

Could you show us the code that is failing?
