fit-PC sells a box (the Intense PC) that is rebranded as the MintBox 2, which has Linux Mint preinstalled, with the Linux Mint project getting a cut of the profits.
Clement Lefebvre, the honcho at Linux Mint, notes[1] that the firmware has a security vulnerability which needs to be patched. Hilariously, the manufacturer's instructions call out a MS Windows-only tool.
[1] In the comments there, Clem responds to Kim, saying that Linux Mint has the tools available to get the job done. In the comments attached to a clickbait article at BetaNews, it was mentioned that dd (sometimes referred to as Data Dump), an app that comes with pretty much every Linux distro, will also do the task.

If I had to implement something of the sort, FreeDOS is likely what I would use as well.
That said, the procedures referred to above seem to call for Win32 Disk Imager, a utility built for Windows using QT 5.2.1 and MinGW 4.8, so the said firmware seems quite accessible.
dd is more direct than the 'Windows' procedure and it would be trivial to hide the procedure under a GUI layer if there was any motivation from the manufacturer of fit-PC to enhance their product for non geeks.
This said, they at least have a linux option.
