Accessing physical memory

I would like to use an I/O board (8255 chip set) that uses lets say a base address range of 300H (Prototype function range).

How does one bypass the "virtual memory" and get/set some physical memory?

Any help would be appreciated.

OS-MS 2000, MS C++ v6.x

WinNT doesn't give you direct access to anything outside your processes virtual memory space without some form of driver or hack. Do a search for 'giveio' in your favourite search engine.

Go figure, thanks for the help

So what's a good template for an NT driver?
