    DevC++ SVGA

    I am using DeVC++ on win2k. I am playing around with the following code but it will not work, my guess is that win2k will not allow me to access vesa bios. Thanks in advance , Oh if this thread double post I'm sorry, do not know what happened the firest time

    [code]

    #include <iostream.h>
    #include <stdlib.h>

    void set_mode(void)
    {
    asm("movw $0x4f02, %ax");
    asm("movw $0x0103, %bx");
    asm("int $0x10");
    }

    int main(int argc, char *argv[])
    {
    cout <<"This is just a test" <<endl;
    set_mode();
    system("PAUSE");
    return(0);
    }

    Nope....welcome to a proper protected mode OS.....

    You need to run in ring 0 to be able to access bios directly......

    Best bet for graphics, spend some time learning OpenGL or DirectX
