[edk] AtapiPassThru

[Ian N. <ian...@ho...>]

 Hello,

Doing a build of OptionRomPkg, I got the AtapiPassThruDxe.efi and AtapiPassThruDxe.rom

Using load AtapiPassThruDxe.efi, I always failed in AtapiScsiPassThruDriverBindingSupported () as soon as I loaded 
Status = gBS->OpenProtocol (
                  Controller,
                  &gEfiPciIoProtocolGuid,
                  (VOID **) &PciIo,
                  This->DriverBindingHandle,
                  Controller,
                  EFI_OPEN_PROTOCOL_BY_DRIVER
);

So, what's the reason?

I've
 an Asus P8H67V motherboard with EFI BIOS and it has an IDE connector on
 it.  An IDE drive is hooked up and in EFI shell, I see it as fs0:

Thanks!
