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

[C++ Programming]

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.
