We use a special card in a PC. The first release of software was written under C and MSDOS. We access to this card throught physical location D000:0000 to D300:00FF.
We have to upgrade our software with Delphi 2 and WIN95.
Due the protected mode, we encountered problems to understand how to access to physical memory location -read and write-.

When going to Win95 the freedom of geting direct acces to your card vanish. You have to get premission by Win95 to do anything you want to do.
The best way for you is to get the DirectX-components from microsoft, which makes the direct-acces-process alot easier and you will now be able to make some realy fast stuff again.

Hope this helps, Steff
