I have a laptop that will not allow anything but UEFI and I must run FreeDOS… (or one of many other OSes that wont boot via UEFI)
Is there a UEFI Bios shim? UEFI thinks it is an OS, but It loads the BIOS boot block and runs it?
Is that even possible?
might be possible to use seabios as a UEFI boot and have it act as a bios (as it is a bios “emulator”), never been down that rabbit hole, but perhaps there is someone who has if you search / ask around
Git repo of seabios: https://github.com/coreboot/seabios/tree/master
not sure if it will work, just hit me when I read this. anyways, good luck, hope you get it sorted/working 🙂
