Thanks Neil, I use both, especially if grepping does not reveal what I am looking for. > The search results show what they are and whether they are set.

Fine, my eyesight is not what it used to be, but it can't be this bad! :p Symbol: MICROCODE [=n] Type : boolean Prompt: CPU microcode loading support Location: (1) -> Processor type and features Defined at arch/x86/Kconfig:1125 Depends on: (CPU_SUP_AMD [=y] || CPU_SUP_INTEL [=y]) && BLK_DEV_INITRD Selects: FW_LOADER [=y] I built this 4.4.6 kernel with oldconfig, so it *should* retain previously selected modules, like MICROCODE. Either way, why would it not show in menuconfig, if a search says it is? -- Regards, Mick
