This means only onboard graphics can be used until +the OS or SeaBIOS initialise PCI graphics cards. +This patch allows us to do a little hack. We can set "Use native graphics +init" to "Run VGA Option ROMs" and activate "Load Option ROMs on PCI +devices". This way coreboot will load the Option ROM on PCI graphics cards +which means payloads like GRUB can display graphics. +There's only one catch: onboard graphics won't work anymore. Because of this +we'll include seavgabios.bin (compiled by SeaBIOS) in CBFS. This will give +us the option to use both PCI graphics cards and onboard graphics that work +with native graphics init. +--- + src/mainboard/asus/kcma-d8/Kconfig | 1 - + 1 file changed, 1 deletion(-) + +diff --git a/src/mainboard/asus/kcma-d8/Kconfig b/src/mainboard/asus/kcma-d8/Kconfig +index d568ff579b..adba4df782 100644 +--- a/src/mainboard/asus/kcma-d8/Kconfig ++++ b/src/mainboard/asus/kcma-d8/Kconfig +@@ -29,7 +29,6 @@ config BOARD_SPECIFIC_OPTIONS + select SPI_FLASH + select DRIVERS_I2C_W83795 + select DRIVERS_ASPEED_AST2050 +- select MAINBOARD_FORCE_NATIVE_VGA_INIT + select POWER_STATE_DEFAULT_ON_AFTER_FAILURE + + config MAINBOARD_DIR +-- +2.25.1 + diff --git a/resources/coreboot/fam15h_rdimm/patches/0003-Tweak-cmos-defaults-for-KCMA-D8-for-a-little-speed-b.patch b/resources/coreboot/fam15h_rdimm/patches/0003-Tweak-cmos-defaults-for-KCMA-D8-for-a-little-speed-b.patch new file mode 100644 index 00000000..5a39bd69 --- /dev/null +++ b/resources/coreboot/fam15h_rdimm/patches/0003-Tweak-cmos-defaults-for-KCMA-D8-for-a-little-speed-b.patch @@ -0,0 +1,38 @@ +From 7a00638cea41ad939a59fc0e5996959435fbdb7f Mon Sep 17 00:00:00 2001 +From: "D.d.P.F.
