Initially the only I/O will be a serial port or two, but I'll add an interface for an SD card if I can get as far as booting from flash into a monitor.
Has anyone written an open-source x86 (386 or newer) 32-bit protected mode boot/debug monitor for bare metal?
There won't be any secret motherboard/BIOS vendor binary blob code doing sneaky stuff in System Management Mode, and they didn't have the secret Management Engine (ME) crap back then either.

I might eventually try to get FreeBSD 1.1.5 or a tiny Linux running on it. The first iteration will likely have only about 4 MiB of fast (10 ns) static RAM.
