you wrote before:
"AFAIK boot managers like Grub can boot a SeaBIOS image from a regular storage media. A SeaBIOS image can be a full BIOS implementation or a CSM depending on how it was compiled. So you can theoretically chain-boot to DOS even on an UEFI class 3 machine."

here theoretically is the word to watch. has it been shown in practice?

complete nonsense. DOS doesn't provide ANY BIOS interface. DOS entirely relies on BIOS to provide services. BIOS interface would/should be served by SEABIOS. DOS is not involved in BIOS stuff.

whatever combination of bootmanagers, UEFI or SEABIOS is involved: it's fairly well documented what is expected from the environment for 'DOS'
