I have programmed the ROM to instantaneously copy my ROM to RAM and run. The entire system is running instantly as soon as I power on. There is absolutely nothing else.
Because everything else is a big mess:
Intel ME, BIOS, UEFI, kernels are signed by companies with Microsoft's blessing, EFI, FAT, TPM, anything with the word "Secure" in it, ...
I want this because right now I use camera cards to boot. The key needs to be wired directly to the processor and be the first and only entry point. Instantaneous boot is what I want, not resuming from hibernation but "instant on" of the full system.
> What are you booting?
I am booting Linux, BSD, custom systems, lightweight bootstrap programs that do a specific task like diagnostics.
> On which architecture / machine?
Agnostic / various. For instance, instantaneously booting / running only on GPU(s).
