He instructions want you to put a formated DOS boot disk in your first
floppy drive and cp it to an image file so that pcemu can use that
image to boot from.

Part of the unix file system mantra is that everything can be treated
as a file. This means that you don't need a special command to copy
the entire contents of a disk or tape to a file, cp will do just fine
since there are no devices, only "special files". If you don't believe
this and want to use an esoteric command to make the boot floppy use:
$ dd if=/dev/fd0 of=DriveA
don't be surprised if it does the same thing as the cp command though.

He just needs the image of a boot disk so he has a copy of the files
needed to run ms-dog. pcemu can interpret them from either the disk or
the file. It's that unix a-device-is-a-file thing again.

Try them as written or use the dd command I gave you. Though the
wording is a bit more sarcastic then I would use the content is 100%
correct.
