 You can us the 'lspci' command to list existing pci devices.
 
+The 'rombar' option determines whether or not the device's ROM will be visible in the guest's memory map (default is 'on').
+
+The 'driver' option is currently ignored.
+
 Note: This option allows direct access to host hardware. So it is no longer possible to migrate such machines - use with special care.
 
 Experimental: user reported problems with this option.
