There are two files on your computer that will need to be changed, AUTOEXEC.BAT and CONFIG.SYS. You will need a plain DOS text editor to make the changes, one that does not create special characters in a text file. If you look at this it will give you the basic idea of what you need to do. However I am pretty certain that Acer will not be able to supply you with the DOS drivers you need as Windows 3.1 is so old.

Well, if forty-eight million, two hundred thousand, seven hundred and one people died I'd be Queen.
