Not an expansion ROM, that suggests the ROM is part of a PCI
expansion card (sound card, networking card, graphics card, RAID card
etc) but some southbridges support decoding the BIOS address range to
the PCI bus. There has to be a jumper for this on the board in order
to work.

In that case, a simple PCI card could be designed with just a flash
chip and probably little more, and this could be booted from.

The board would likely need to be double sided though, so not trivial
to produce at home. (But prototype quality boards can be gotten
fairly cheap.)
