To change disks simply press Ctrl-F4 until the next disk is in the A: drive.Īfter the installation is complete, you will be asked to remove any floppies and restart. The reason why this tutorial recommends to run DOSBox from the terminal so you can see which floppies are currently loaded in the A: and B: drives.

The installation will prompt you to change disks. Then all you need to do is follow the prompts on the screen. You may now launch DOSBox from the terminal, which will boot from the first floppy image referenced so make sure it’s the correct disk.

Now add the relevant floppy images to the “BOOT” parameter so that DOSBox will boot from the first installation disk to install MS-DOS 6.22. 520 is the calculated number of cylinders. The numbers ‘512,63,16’ can remain unchanged. Open the DOSBox config file, go to the ‘autoexec’ section, and insert the IMGMOUNT command that needs to run. I have used random cylinder numbers without issue however, I would still recommend that you follow what the DOSBox Wiki recommends to ensure that you run into a few problems as possible. If you used ‘dd’ instead, you can calculate the number of cylinders by multiplying the size of the image in megabytes by 2.03125 (C = S * 2.03125). You will need it for the DOSBox IMGMOUNT command as it requires data about the disk structure. Take note of the number of cylinders from bximage. All you do is run the command in the terminal and accept all of the defaults, but you may, of course, want to change the filename.

You can download and install this without having to download Bochs itself. The other program you can use is bximage. To do this, run dd: $ dd if=/dev/zero of=./256MBHDD.img bs=1M count=256 Using ‘dd’ Or ‘bximage’Ī hard drive with a reasonable capacity should be created. The other (which is covered here) is using ‘dd’ and fdisk.

The first is using the disk image generator that comes with Bochs PC (bximage) to create the disk image. This step would have to be the most complicated as it involves not only creating the image but also gathering a few details of the image such as disk information.

This guide continues on from that as it goes through step by step how to properly create a hard disk image, hook it up to DOSBox, and install whichever DOS you want, be it MS-DOS, PC-DOS, or DR-DOS. So if you know the '8.3' file name of a file (which is always stored as exactly 11 bytes on the disk), you will not search the disk for the 'long' name.The previous tutorial demonstrated the simplicity of booting from floppy images and creating other images using the tools provided by Linux. However, the 'long' file name is more difficult to read from the disk than the '8.3' file name.

If you store a file named ' StackOverflow.html' to a FAT-formatted disk, the file will actually be named ' STACKO~1.HTM' (8 + 3 characters) and Windows stores some additional information that the file is also named ' StackOverflow.html'. Windows internally still uses this '8.3' scheme, however, it additionally stores a 'long' file name visible to the user for each file. Trying to store a file named ' StackOverflow.html' would have resulted in storing a file named ' STACKOVE.HTM'. that MS-DOS only supported upper-case file names and it did not support file names that did not match the 'up to 8 characters + up to 3 characters' scheme. The two parts are filled with space characters if the are not long enough. On the disk, the name is always stored as exactly 8 characters followed by exactly 3 characters with no dot in between. ') are stored this way:Ī file has a name of up to 8 characters, optionally followed by a dot followed by up to 3 characters. On FAT-formatted floppy disks, all files (with exception of the special directory names '. The next question is why io.sys and msdos.sys are 11 characters long with no dot ('. For example using a program or tool that is delivered together with the operating system.Įarly Linux versions (for example) came with a tool named ' rawrite.exe' that allowed writing a boot disk image (or a boot sector) when MS-DOS or Windows was already installed on the computer. Other operating systems (for example self-written operating systems) use special boot sectors in this case the boot sector must be written later on. However, in later MS-DOS versions, the ' sys' tool (copying io.sys and msdos.sys to the disk) wrote the boot sector to the floppy disk anyway to ensure that the correct boot sector is installed in some earlier MS-DOS versions the ' sys' tool seemed to rely on the fact that the disk already contained a correct boot sector. Under MS-DOS the program which formats the floppy disk (the format program): All floppy disks formatted by MS-DOS initially contain a boot sector that allows booting MS-DOS (or Windows 9x).
