accessing PCI memory in Windows 95 DOS Box
We want to access PCI memory in a windows 95 DosBox.
The PCI memory resides eg on address 0xe4000000 to 0xe40800000
Everytime we access the memory, we get an invalid page exception.
The program is written in turbo pascal and works great in plain DOS (so no
DOSBOX), so I am pretty sure the code is correct .
Do we have to reserve the memory or ..... any other suggestions?
