In map_oprom_vendev_rev(), we look at the cpuid and decide which rom to load. Even though the hardware has the same vendor/device IDs, the vBIOS contains a *different* device ID, confusing the situation even more. config VGA_BIOS_SECOND_FILE string default "3rdparty/amd_blobs/picasso/Raven2GenericVbios.bin" config CHECK_REV_IN_OPROM_NAME bool default y help Select this in the platform BIOS or chipset if the option rom has a revision that needs to be checked when searching CBFS. config S3_VGA_ROM_RUN bool default n config HEAP_SIZE hex default 0xc0000 config SERIRQ_CONTINUOUS_MODE bool default n help Set this option to y for serial IRQ in continuous mode.
