Vbox used MMIO and port I/O before moving the splash support to the VGA device.

I think Vbox used run-length encoding for the innotek logo bitmap. Its size was
about 10 KB. If this could be used for Bochs we could put the logo into rombios32.bin
and load it from the 0xe000 segment. This should be comparable to other BIOSes.
