I have DOS 7.1 and have gone to their site to try and find out how to edit config.sys but I couldn't figure it out.

I need to add two lines to it.  If someone could tell me in a SIMPLIFIED manner how I MIGHT go about doing this, it'd be great.

I also don't KNOW how to edit or copy from and paste into text files.  This would be helpful as I have a file that has the two lines in it if I wanted to easily add onto the config file.At the c:\ prompt, type edit config.sys<enter>
You cannot cut and paste in DOS unless you have a utility that permits it. You will have to do your editing manually. Cut or Copy and Paste is a function of the Windows clipboard.thank you much.

how do I save and exit out of config?Press the alt key to activate the menu bar. You can navigate with the arrow keys or simply press the highlighted letter for a particular function. F for file drop down menu. Select save. Do it again and select exit.Alternatively you could install DOS mouse drivers.

Add a line in your autoexec.bat to make it AUTOMATICALLY load.
