Simply run ‘mkfs.fat’ on the image to create the filesystem. Now that the partition is defined, it needs to be formatted. Print the partition type using ‘p’ to see the change, and then press ‘w’ to write the changes to the image. Press ‘L’ to find the code to enter for FAT16 (not <= 32M). Next step is to run fdisk on the image itself to create the FAT16 partition: $ fdisk documents.img First, let’s create the actual file itself using ‘dd’: $ dd if=/dev/zero of=documents.img bs=1K count=1440Ī standard 1.44MB floppy image has been created using ‘dd’. On systems like Ubuntu, you should already have these tools installed. The tools needed are ‘dd’, ‘fdisk’, and ‘mkfs.fat’. The command line will be used to create the images. Ctrl-F4 will then go back to the beginning of the floppy list. ![]() To cycle through the loaded images, press Ctrl-F4 to put the next set of floppies into their drives, so “documents.img” goes into A: and “games1.img” into B: Pressing Ctrl-F4 again will put “games1.img” into A: and “games2.img”. ![]() DOSBox will treat the DOS 6.22 image as the A: drive and the “documents.img” file as the B: drive. This will boot into MS-DOS 6.22 with the option to cycle through the images. boot “MSDOS622.IMG” “documents.img” “games1.img” “games2.img” -l a Again, it is recommended to put these floppies in the same directory as the boot image just to make it easier down the track, but that is entirely up to you. Multiple FloppiesĭOSBox can take multiple floppy images as parameters for the boot command. Note that “-l a” simply tells “boot” to boot from the A: drive. boot “MSDOS622.IMG” -l a DOSBox should successfully boot the floppy image. Y: Now run the boot command to boot from the image as well as specifying the drive to boot from. Mount Y: /home/unix_allsort/.dosbox/floppies My recommendation is to mount the directory where you intend to keep your floppies first, then navigate to them to reference the floppy image file. Once the floppy image has been obtained, open up the DOSBox config file and scroll to the bottom of the autoexec section to insert some commands that will allow you to easily boot from an image. Look for an MS-DOS 6.22 boot disk as an example. ![]() This guide will also show you how to load several floppies at once using the “boot” command in DOSBox. To start with, all that is needed is a disk image that will boot into MS-DOS. There are places you can visit on the Internet where you can download DOS systems in the form of bootable disk images. This can be simulated by using a floppy image which is simply a file that represents an entire floppy disk drive. Many floppies contained games or other software that would have automatically booted once the system started (using the autoexec.bat script). Continuing on from the previous tutorial, we move on to boot DOS systems from floppy images. ![]()
