ExpRomBaseAddress allows the system to define the base address for the adapter’s Expansion ROM.
ExpRomBaseAddress is disabled (read only with a value of 0x00000000) when the IP100 is in Multi-Function
Mode (see the Reserved/MultiFunction bit in the AsicCtrl register).

AddressDecode-
Enable
IP100’s Expansion ROM is disabled. If AddressDecodeEnable is a
logic 1, and the MemorySpace bit in the ConfigCommand register is
a logic 1, the IP100 will respond to accesses to the expansion ROM
space.

RomBaseAddress
R/W
ROM Base Address. RomBaseAddress contains the expansion
ROM base address, or the upper 16 bits (or 15 bits, depending on
the state of the ExpRomSize bit in the AsicCtrl register) of the
Expansion ROM address range.
If the ExpRomSize bit in the AsicCtrl register is a logic 0, all 16 bits
of RomBaseAddress are valid. If the ExpRomSize bit in the AsicCtrl
register is a logic 1, bits 31 through 16 of RomBaseAddress are
valid, with bit 15 ignored (set to a logic 0) during write operations.
