In menuconfig, when you open the help on an item, there is a line "Depends on". If the requirement is not met, the option is not visible but can be found by searching (press /). There might also be a line "Selects" which contains automatically activated dependencies and "Selected by" which contains the reverse dependencies. >> Are there patches for older computers? >> Don't think so.
