When searching for an UNDI ROM to match against a PCI device, search in order of increasing ROM address (within the 128kB BIOS option ROM area). This is likely (though not guaranteed) to match the order of the original enumeration performed by the BIOS, which is in turn likely to match the order of enumeration on the PCI bus. Since we load at most one UNDI ROM, the net result is that we increase our chances of loading the ROM corresponding to the selected PCI device (rather than loading a ROM corresponding to a higher-numbered PCI device with the same vendor and device IDs.)
