PREFACE

Installing Windows NT from CD, HDD or floppies as usual on modern hardware (I mean Pentium4-based and later PCs) it is a difficult task due to installer incompatibility with faster/newer hardware & CPUs. That doesnt mean that Windows NT cannot RUN on such hardware. You CAN install Windows NT in virtialization software (QEMU, VirtualBox, VmWare, VirtualPC, Bochs ...) and then copy intalled OS image on "real" PC harddrive.


General installation notes

On modern systems like Pentium-II CPUs or higher you may expect problems when installing NT 3.1 or updating it with service pack. To resolve these problems you must edit these files:
Differences in writing drivers compared with newer NT systems

  1. The sources file used to build the driver must include the following line:
    DRIVER_ALIGNMENT=0x200
    Windows NT 3.5 (and later) allows image sections to be aligned on 32-byte boundaries, but Windows NT 3.1 requires them to be aligned on 512-byte boundaries. If you do not add this line to your sources file, Windows NT 3.1 will refuse to load your driver, reporting an invalid image format error.
  2. The PE-header of driver file must include the following version numbers: Don't forget to recalculate checksum of driver file. You can use editbin tool from Microsoft's Visual Studio or Platform SDK:
    editbin /RELEASE MSGINA.DLL
  3. Some structures changed when Windows NT 3.51 is released so keep an eye for it. I'll take for example VIDEO_HW_INITIALIZATION_DATA and VIDEO_PORT_CONFIG_INFO structures from video.h.
    //
    // Structure passed by the miniport entry point to the video port
    // initialization routine.
    //
    
    typedef struct _VIDEO_HW_INITIALIZATION_DATA {
    
        ULONG HwInitDataSize;
        INTERFACE_TYPE AdapterInterfaceType;
        PVIDEO_HW_FIND_ADAPTER HwFindAdapter;
        PVIDEO_HW_INITIALIZE HwInitialize;
        PVIDEO_HW_INTERRUPT HwInterrupt;
        PVIDEO_HW_START_IO HwStartIO;
        ULONG HwDeviceExtensionSize;
        ULONG StartingDeviceNumber;
    
        // New for version 3.5 and later - REMOVE IT!!!
    
        PVIDEO_HW_RESET_HW HwResetHw;
        PVIDEO_HW_TIMER HwTimer;
    
    } VIDEO_HW_INITIALIZATION_DATA, *PVIDEO_HW_INITIALIZATION_DATA;
    

    typedef struct _VIDEO_PORT_CONFIG_INFO {
    
        ULONG Length;
        ULONG SystemIoBusNumber;
        INTERFACE_TYPE AdapterInterfaceType;
        ULONG BusInterruptLevel;
        ULONG BusInterruptVector;
        KINTERRUPT_MODE InterruptMode;
        ULONG NumEmulatorAccessEntries;
        PEMULATOR_ACCESS_ENTRY EmulatorAccessEntries;
        ULONG EmulatorAccessEntriesContext;
        PHYSICAL_ADDRESS VdmPhysicalVideoMemoryAddress;
        ULONG VdmPhysicalVideoMemoryLength;
        ULONG HardwareStateSize;
    
        // New for version 3.5 and later - REMOVE IT!!!
    
        ULONG DmaChannel;
        ULONG DmaPort;
        UCHAR InterruptShareable;
    
    } VIDEO_PORT_CONFIG_INFO, *PVIDEO_PORT_CONFIG_INFO;
    
  4. Also you must keep an eye for missing ntoskrnl, ntdll, kernel32, user32, gdi32, advapi32, shell32 and other functions/procedures.
