I don't think this is as easy as it used to be, with
all the chipsets, etc.
On an old PC, you could put a magic header and a
checksum on a 2716, and basically load an .EXE file
into the EPROM. After initialization, the PC BIOS
would look for "extra" chips just "under" the BIOS and
above the EGA area for additional code. To this day, I
beleive that this is the way network cards with BOOTP
capability work. on a "real" PC, you can remove the
BASIC chips and do this.
