From: Patrick Rudolph <[email protected]> The Option ROM scanner can't work as enumeration was done by the first stage bootloader. Running it will disable the ability of the PCIPlatform code to scan for ROMs.
Required for the following patch that enables custom Option ROM scanning using gPciPlatformProtocol.
