*Notes:
This register handles the base address and size information for the expansion
ROM. It functions exactly like the Base Address registers, except that the
encoding of the bits is different.
The Expansion ROM Enable bit, bit 0, is the only bit defined in this register.
This bit controls whether or not the device accepts accesses to its expansion
ROM. When the bit is set, address decoding is enabled, and a device is used with
or without an expansion ROM depending on the system configuratio. To access
the external memory interface, also set the Memory Space bit in the Command
register. It exists in function 0 only!
