    Rom Bios

    I have the following simple code which retreives the amount of memory from a system:

    Code:
    #include <iostream.h>
    #include <dos.h>
    
    int main()
    {
    	const MEM = 0x12;
    	
    	// inregs and outregs variables used in int86() are of union type REGS
    	REGS regs;
    
    	int86(MEM, &regs, &regs);
    
    	cout << "\nMemory size:" << regs.x.ax;
    }
    I compile this program using Visual C++ without any error, but when I execute it I receive an error message saying it cannot execute the program.

    Any ideas?
    Thanks.

    the &reg is actually:
    Code:
    & r e g s  // all together

    You need an old dos compiler. Visual c is a windows compiler.
    Free the weed!! Class B to class C is not good enough!!
