Installing FreeDOS in DOSBox-X
FreeDOS is a free and open-source re-implementation of DOS.
This installation method uses the FreeDOS 1.3 LegacyCD download.
Creating a HDD image file
|In addition to the below DOSBox-X command line utility, it is possible to create harddisk images from the DOSBox-X menu. Go to the "DOS" menu, and select "Create blank disk image…". This option allows for various common harddisk types to be created, for less common types you need to use the command line utility.|
From the DOSBox-X command prompt:
IMGMAKE hdd.img -t hd -size 2048 IMGMOUNT C hdd.img
The above example creates a 2GiB HDD image. You can obviously use a different size, up to 2TiB.
Next step is to mount and boot the (El-Torito) ISO CD image.
IMGMOUNT D FD13LGCY.iso IMGMOUNT A -bootcd D BOOT A:
It will now boot to the setup program. You should be able to follow the on-screen installation prompts.
After it finished the installation, it will reboot DOSBox-X and your again at the
Z:\> prompt. Now type the following to boot FreeDOS normally.
IMGMOUNT C hdd.img BOOT C:
These last lines can be added to the
[autoexec] section of your DOSBox-X config file to automatically mount and boot FreeDOS.
