Hello everyone, I'm new in this forum. I have four floppy image files (*.img) of the diskettes of MS-DOS 6.22 and I want to combine them into one *.iso file in order to make a bootable USB drive (I use Rufus for that). Is there a way to do that? P.S.: I've already searched a solution on web, and I found a bootable *.iso image of MS-DOS 6.22 on allbootdisks.com, but there is a problem: the edition of MS-DOS 6.22 of my four *.img files is different from the one of the *.iso image found on that website... P.P.S.: pardon my English.
