Correct.  They don't.  I'm trying to see what it will take to make them.

I don't need general expansion rom support.  All I need for ADLO is a 
valid memory range assigned to the VGA expansion ROM.  Then my chipset 
code can enable the rom and do the shadowing copy.

"PCI Hardware and Software. Architecture and Design" by Edward Solari 
and George Willse.  It has a red cover.
