Instead, AMD needs to issue an update to AGESA, fixing this issue, followed by sending AGESA to affected manufacturers (only two seem to use this chipset anyway, including HP), and HP releasing a firmware update that bundles the updated AGESA, solving the issue. It appears AGESA is incapable of disabling the integrated graphics chipset inside of the CPU, because it does not support that function on the AMD Promontory FCH chipset, unlike other AMD chipsets, which can disable the integrated graphics chipset on the exact same included CPU, the AMD Ryzen 5 2400G, meaning it would be impossible for HP to actually fix this issue. ![]() This appears not to be an issue with the BIOS, but an issue with AGESA (or, AMD Generic Encapsulated Software Architecture), and poor support for the AMD Promontory FCH chipset, which the HP Sunflower motherboard uses on the HP Pavilion 690-0024.
