As indicated before, I also have a Debian 8 latop, which is perfectly fine for my daily tasks, and hence, I do not have the desire to discard the Linux running on it, in particular since everything, including WLAN is running perfectly on this hardware.
This latop, a HP/Compaq nx6110, was also able to run the FreeDOS live-CD.
Anyway, I installed FreeDOS on a virtual drive on this particular computer. Again, the hardware, i.e. keyboard, is just perfect for my regular use under Linux.
When installing the FreeDOS image, I encountered some minor problems getting the networking to up and running. Finally, I ended up with a script as follows:
#!/bin/bash
qemu-system-i386 -m 32M -drive file=drivec.img,media=disk,format=raw -net nic,model=pcnet -net user
With this script, I am able to browse the internet using Lynx. I am pretty sure that I will be able to use other network services too.
