At 0000H I find C3 03 D3. An easy way to add the routine would be to make the jump go to the user bios area, and then jump to D303H. However, I can't find on the DISK the bytes that live at 0000H in the MEMORY once I have booted. Does anyone know how these three bytes are generated and placed in memory? George
