Few PCI cards have ROMs any more.  Your graphics card is just about the
only one left.

The only way to get this information authoritatively is to enumerate
through the configuration space of all of the devices on your PCI bus. 
You
can do that using the PCI BIOS interrupt, INT 1A.  The expansion ROM base
address is in the configuration space at offset 30h.
