Thanks very much Eric, I'll get a PC spec'd up with a motherboard I've been recommended!

Yes it will. You confused AMD with ARM. FreeDOS will run on AMD CPU and I have an AMD based PC with FreeDOS :-) It will not run directly on ARM hardware, which includes devices like most Android smartphones and tablets.

Raspberry Pi, for example, use Broadcom System-on-a-Chip with ARM processor architecture. > I believe you could also use the same tricks to run on a UEFI Intel... People have tried to build DOS compatible CSM for UEFI, but this is still very experimental. Because UEFI is not a BIOS, you have to load additional modules (CSM) to implement the BIOS functionality required to natively run DOS. Until a few years ago, most computers still gave you the choice between booting "legacy" BIOS and modern UEFI based operating systems. Recently, computers without BIOS support became the norm. You cannot easily run DOS directly on such hardware, no matter which brand of processor it includes.
