The ROM startup is configured to boot the I386 from its reset
vector. I only ever tested it on the Bochs simulator, never on real
hardware. At the very least it would probably need some additional
hardware-specific code to complete the hardware initialization.
I don't know what the requirements for booting an application from
flash via the BIOS might be. There is no support for that in the
current sources.
