Execute the following command to observe one bye of the memory content at CS:0100h -d cs:100 100 What command would you use to display 8 bytes of the memory contents starting at CS:0100h? Command, Use the command f to fill the memory with data. The following command fills "5A" into the memory locations from offset Oh to ffh in the data segment. -f 0 ff 5A What command would allow you to see if the command above works? Command Use the command e to enter memory contents. -e 100 'Hello' What command could you use to see the word Hello in memory? Command What are the ASCII values you see in debug for each of the letters of the word Hello?

CMPE 3437/ELEE 3435 Lab 01: DOS Debug A. Objectives: to get familiar with the debug program and use debug commands to examine registers and memory contents. B. Resources 1. Online resources 2. Textbook C. Lab Preparation 1. Read the online guide or textbook to understand the debug commands used in the assignment. 2. Start the Debug Application. Note that in the lab report, you will be required to show the results you obtained in your experiments. You thus need to take screenshots of your work. D. The Lab You will practice some commands useful in debug, such as the dump, enter, and fill commands. First, execute the following command to fill the memory with some data: -f 0 fff ac cb f5 4e 65 8d 1. Execute the command r to examine the contents of registers. You can change the value of a register by doing the following. -r IP IP 0100 Now you can enter a new value for the IP register after the prompt. 2. Display and modify memory contents. Use the command d to dump (display) the memory contents from the data segment. -d 100 120 This will display the memory contents from DS:0100h to DS:0120h (all numbers are in HEX). The 100h and 120h are offset addresses. Document the values you see in the following lines. DS:0100h =. DS:0108h = DS:010eh = Execute the following command to observe 128 bytes of memory content in the stack segment starting at the offset of 0100h. -d ss:100
