For UEFI it was just a matter of translating the UEFI scancodes/modifier mask into an ANSI escape. For BIOS, I had to jump through some hoops since scancodes change based on modifiers (and didn't follow any patterns), but it was nothing a lookup table couldn't fix. u-boot was a bit of a different story though, since it already provides input via ANSI escapes, but doesn't implement all special keys or all key/modifiers combos. Beyond needing upstream changes, I also ran into the problem of my changes not having any effect. Both physical and virtualized hardware didn't seem to reach my code (despite it being present in the binary). I assume this is simply for a u-boot/non-x86 specific reason I don't fully understand yet. Since I didn't specifically plan for u-boot support in my proposal, I'm just going to let this problem stew while I get more familiar with the non-x86 booting world and try again later on. Connor
