Around 2005, I had a specialized PC104 CPU where I ran a Debian OS on my railcars. Linux kernel code added a dependency on a new CPU instruction that was not supported by the SOC custom CPU on the Diamond Systems PC104 CPU board. I was locked into an old kernel. A change in administration occurred on January 20, 2009. The project was defunded upon the arrival of Obama. I sent the obsolete CPU boards back to the project office. The problem was overcome by events (election) and never resolved.
I hadn’t known that new Linux releases REQUIRE UEFI. Heck, I remember it was controversial when Intel put a unique processor ID on 486 processors. Are there any new Linux releases that do not require UEFI? I thought that was mainly a MS thing.
