by Dustin Cogburn

This is a tutorial about windows Debug command. This tutorial is made by dustin cogburn and is based off what i have learned about the debug command. This tutorial is for Windows XP home

Ok, we will start by making a hello world display in your ram.

1. go to start/run/cmd
2. type debug and hit enter
3.Type the following and hit enter after EVERY line
-E 0100 BE 0D 01 B4 0E B1 0C AC CD 10 E2 FB C3 48 65 6C
-E 0110 6C 6F 20 57 6F 72 6C 64 21
-g
*note do not type the little - also when you hit g and enter it should execute "hello world"
by typing "g" you execute the program.
it should look similar to the following
