TUTORIAL
HOW TO INSTALL & USE
DOSBOX
ON
64-BIT OPERATING SYSTEM
FIRST OF ALL
We have to download
DOSBOX application from
LMS site.
We have already
installed NASM
assembler in
C:\ directory
Our first code
“ex01.asm” has been
saved in the
“C:\assembly” directory
After installing DOSBOX, You
will get a DOSBOX shortcut on
your desktop.
After opening
DOSBOX, you
will get an
interface like this.
First of all, you have to mount
the c:\assembly folder.
For that you have to type
“mount m: c:\assembly”
And press enter
Now C:\assembly has
been mounted on m:
drive
Now change your
current directory to
m:
You have to write
“m:” and press enter
Current directory has
been changed from Z:
to M:
Now we are going to assemble our first code
that we have saved in C:\assembly drive
named as “ex01.asm”
Just type the command
“nasm ex01.asm –o ex01.com –l ex01.lst”
And press enter.
Our code has
been assembled
without any error
Now we have to run AFD
using DOSBOX.
We have just written the
command
“afd ex01.com”
And press enter.
Debugger has
been opened
After assembling
“ex01.asm”.
“ex01.com” and
“ex01.lst” files has
been created
In order to view you
“ex01.lst” file
We have to use
“type” command
EDIT COMMAND
• In case of DOSBOX, if you want to make
some changes in “.lst” file using “edit”
command as we did in pure NASM. You
have to make changes in main “.asm” file.
• For example:
– If you want to edit “ex01.lst” you have to edit
manually “ex01.asm”.
