I updated today to the latest 10.4.10 on my PB G4 (1.25 GHz). Before on 10.4.9 (installed a few months ago) it was OK. After the ugrade I noted that the memory in the lower slot (256 MB) is not seen. The upper slot (1 GB) is still visible. Didn't check right before the update. But since the motherboard is relatively young (start 2006), I (still) assume that the m'board did not die.
Reseating the modules and resetting the PMU did not fix it. I still assume it may be a bug (feature ?).
Reboot from disk with 10.3.9 : still memory lost. Argghh.
Noted on several forums similar issues appleinsider on 10.4.10 and the http://lowermemoryslot.editkid.com/
Frequent reports seen on loss on memory with upgrades. Clear: maybe that's the time that you check it.
But the number of reports appear statistically too frequent, to be meaningless.
Ran image backup, noted that a start from disk with 10.3.9 showed still memory loss.
So the upgrade to 10.4.10 appears to be be the cause for my loss of the lower memory slot. @$!&$$*^!!
Apple owes us an explanation, but I fear that 'silence' is a planned strategy here.
Apple should better go after it. Especially assuming that 10.4.10 is the portal to Leopard.
