 Apparently, only the first 128K of the rom are mirrored to the
 0xc0000-0xfffff area under qemu, so make sure to copy the rom (via
 make_bios_writable) in the non-init part of the startup code.  This
 ensure the copy code is itself available.
This is pretty typical... the BIOS is supposed to fit within the
0xe0000..0xfffff area during actual execution.
