I have tried a few more ways to execute the BIOS upgrade file I downloaded from Dell. None of them worked, but I am documenting them here for the record.
Thinking that FreeDOS was the problem, I tried making an XP MS-DOS bootable USB. This failed in exactly the same way, with the 'Test.' message. This seems to indicate that at least FreeDOS is not the issue here.
I then made a Windows 7 bootable image on USB, and added the executable to the root directory. I used [this link](http://www.intowindows.com/bootable-usb/) to make the bootable media. Booting the USB and selecting X64 Recovery Mode I navigated Install Windows->Repair->Use Recovery Tools->Command Prompt. At the prompt I found the USB media as disk C: and again attempted to run the BIOS upgrade .exe. It failed, but this time the message was different:
'The subsystem needed to support the image type is not present.'
When I can work out what that means I will be a step nearer to running the upgrade...
