Oh, a 512k rom. Where does that come from? The ones shipped by qemu are all between 128k and 256k in size, which gets rounded up to 256k (0x40000). Has not changed since we added efi boot rom support ... If you supply your own versions for some reason you must make sure they have identical size on all host machines. take care, Gerd
