Business idea: eprom based firmware

And put the EPROM in a socket, like it's 1987?

Some motherboards just have a physical jumper that prevents BIOS flashing. This happens infrequently enough as to warrant it for one server, or 10 servers, or maybe 100 servers. Likely unpractical for 1000 servers though.

If they can put the jumper on the exterior it might be feasible, if its inside its out of the question if you have to unrack the chassis to change. Rolling in a server lift for an 8u thats half full of copper is not a nice process

The next idea, a second oob management for the first oob managemen. A BMC for the BMC. It only does updates and maybe credential management.

Make this one simple enough and add an EPROM for it. Effectively a security chip for the oob. Extra points for secure enclave-like verified boot.
