    Exclamation Using BIOS int 10H and int 16H

    need help understanding how to create this program my teacher has explain this only twice and expects me to know it already here are the details.


    Using BIOS int 10H and int 16H interrupts create an elevator floor indictator display simulator (lighted numbers for floors 1-5) . Use int 10H services to create a graphic representation the elevator floor indication display. Use int 16H service 0 to read a number 1 - 5 entered by the user. DO NOT use printf or scanf at all, with the exception that you may use printf to prompt the user for input.

    Entering a 1' or 2 or 3 or 4 or 5 will turn on the corresponding floor indicator light and turn off all others.


    need help someone please respond

    You're kidding right?

    This is MS-DOS stuff.... circa 1985

    What operating system is on the computer, and what IDE/compiler are you using?

    If it's DOS, what version of DOS?

    I think he is using a Power C compiler.

    yes i am using power c compiler

    here is what i have so far

    Code:
    //#include "libepc.h"
    #include "dos.h"
    
    int main(void)
    {
    	char attr1;          // any floor unlit
    	char attr2;         //  any floor lit
    	union REGS r;		//Holds register values for the bios services	
    	int row =12;		//Screen position
    	char ch;			//Character entered by the user
    
    	//  Set Video Mode
    	r.h.ah = 0x00;			//set mode
    	r.h.al = 0x03;			//mode 80 x 25 16 color
    	int86(0x10, &r, &r);
    
    	// create a solid rectangle using the block character
    	for(row = 0; row < 5; row++)

    1: << !! Posting Code? Read this First !! >>

    2: It doesn't matter what version of DOS he's using, 10 and 16 are BIOS interrupts. In general, 1-1F are reserved by Intel for their(and BIOS) use.

    o_O ... What is that, a unreal mode emulator??? Because you know that BIOS can't directly be used in protected mode, right?

    Edit: Oh, now i get it. It's a MS-DOS emulator, hence the "dos.h"
