Lab (6): Loading the DEBUG Program
Objectives
Explain Loading the DEBUG Program.
Part 1:
Start Emu8086 by selecting its icon from the start menu, or by running
Emu8086.exe.
2. Select " Samples " from " File " menu.
3. Click [Compile and Emulate] button (or press F5 hot key).
4. Click [ Single Step ] button (or press F8 hot key), and watch how the cod
is being executed.
5. Try opening other samples, all samples are heavily commented, so it's a
great learning tool.
Part 2: Examining and Modifying the Contents of the 80x86's
Internal Registers
1. Use the REGISTER command to display the current contents of all of the 80x86's internal registers. List the initial values held in CS, DS, and SS. _____________ ,_____________ ,______________
2- Here is a short program that demonstrates the use of MOV instruction:
#MAKE_COM# ; instruct compiler to make COM file. ORG 100h ; directive required for a COM program. MOV AX, 0B800h ; set AX to hexadecimal value of B800h. MOV DS, AX ; copy value of AX to DS. MOV CL, 'A' ; set CL to ASCII code of 'A', it is 41h. MOV CH, 01011111b ; set CH to binary value. MOV BX, 15Eh ; set BX to 15Eh. MOV [BX], CX ; copy contents of CX to memory at B800:015E RET ; returns to operating system.
