Put the BIOS int13 program address into the interrupt vector table under DOS.
How do I do this, and how do I find out the int 13 address? |

Program it with debug
First clear interrupts, that is: CLI ; Then change the memory address pointer corresponding to the interrupt vector you want to modify so that it points to the memory address of the program you wrote yourself; Finally set interrupts again: STI |
