[ubuntu-za] [OT] Make a DOS boot disk

[Charl Wentzel]

Hi Guys

I need to create a DOS boot disk to do a Firmware upgrade on a device. 
Someone sent me the DOS boot files to make it work.  In principle I
should be able to format a USB drive then simply copy the DOS file over
and then it should boot.  However, I'm not having any luck.

I also tried make a FreeDOS disk using UNetbootin, but that didn't boot
either.

Is there an easy way to create a DOS boot disk from an Ubuntu PC? 

Regards
Charl
