Amusingly, to this day it's debatable as to whether EFI has actually got to the point where it's as useful/functional as OpenBoot was 20 years ago, and I'm leaning towards 'no'. Without special server hardware, you still can't hook up a random EFI-equipped PC to a serial line, issue your break and do "boot net"... but I could do that on any Sun box 20 years ago, and a lot more besides. You could even test/enable/disable individual memory banks, disable CPUs on SMP boxes and there was a memory testing function similar to memtest+ built in directly to the hardware, along with a whole bunch of other low level, platform independent tools. > Strangely I thought of a really handy use for it the other day, technically > illegal so never mind.. Oh come on, don't tease us like that. Now I really want to know...
