A fix of sorts for PowerBooks with lower RAM slot issues
Authored by: k0t1k968 on Mar 08, '08 04:57:39PM

Unfortunately trick with nvedit/use-nvramrc? does not work. To the best of my understanding how boot process works, the reason is that nvramrc script gets executed before step on which memory gets "discovered". I do believe that it is possible to avoid it (by explicitly invoking that hardware-testing step from nvramrc script), but could not figure out how to do it :(.

Obviously some % of "broken" PB will become even more "broken" after this fix. If you really have fried memory slot and/or fried memory, fulling with firmware will not make it work. But it does work wonderfully on my wife's PB. She really can feel the difference when playing WoW, so it is quite obvious that PB is able to use memory in that slot.
