This site has links to what are supposed to be live floppy and cd images. Try at own risk.
"Balder requires NO hard disk install, therefore requires no hard disk partition or other dangerous activity. Everything is on the floppy you boot from.
Freedos is also available as an iso for CD in a 39MB installable version - no live version just now. Note- now version 1.1. Note that installing Freedos may overwrite other operating systems or data on your computer. A live CD iso of version 1.0 is available at Freedos 1.0 live CD- download the 153MB iso.
The img file for Balder you have downloaded from the link above needs to be placed onto a real (formatted) floppy as a bootable image-
in Linux the command is:
dd if=/fullpathto/wheretheimagefileis/odin1440.img of=/dev/fd0
where fd0 is the device name in my system for my floppy drive, which for the purpose of this command should be unmounted (a Linux thing). It will be fd0 for the first floppy drive in almost all Linux systems."
I haven't tried them so good luck.
