Hello Matt, Thank you for your response. I see that SeaBIOS still can’t handle the FMAP structure. The pointer depends on the FMAP layout and this is different to chromium devices. For the UP squared board I did not find any other solution than to set CONFIG_CBFS_LOCATION=0xFFFC0000 and to patch the 16M coreboot.rom image at address 0x00EBEFFE with 0x44. Then SeaBIOS will find the CBFS to load the APL VGA BIOS ROM.
