These commands are to be used with the DOS Wedge utility, which was published on the floppy disk that shipped with the 1541 Floppy Disk Drive.
Using the DOS Wedge utility saves the user from having to start each disk command with
OPEN15,8,15 and end with
:CLOSE15. This is a great time saver if you have to perform a lot of disk commands during one session.

Rather than having to load and run the DOS Wedge boot program, you can directly load the “DOS 5.1” ML program and then execute
SYS 52224. To make it even easier to get DOS Wedge running, I have renamed the program from “DOS 5.1” to simply “!”. So, now to load up the DOS Wedge, I just type
In the RUN magazine's special issue of 1986, there was a helpful little program that was published which made it very easy to copy the DOS Wedge utility from memory to floppy disk.
To use the DOS Wedge Improver program, follow these instructions:
NEWand press RETURN.
SYS 52224and press RETURN.
SYS 52400and press RETURN.
The DOS Wedge will now be copied onto the floppy disk in the disk drive, and the computer will then reset itself. To copy to another disk, restart the DOS Wedge utility by typing
SYS52224 and press RETURN, then make drive 8 the active drive by typing
@#8 and press RETURN. Then, save DOS Wedge to a new disk by typing
SYS52400 and press RETURN.
The DOS Wedge Improver makes a small change to the DOS Wedge program, allowing you to copy it to floppy disk by using the
