Hi all.
Playing with my PowerBook g4, and I've noticed that when the splash screen is displayed, it tells me that I have 1.667ghz power PC but only 1.5ghz of system ram. Is this normal? I have 2gb of system ram installed...
Regards Lee

Around 1.5 GB is max. Thats normal.

Memory addresses bigger than 2 GB are causing negative values which broken software, mostly 68K stuff, is handling wrong.

The missing address space is used for system data and functions.

Where does that system data go on systems with less than 1.5GB ?

So there is an advantage to having more then 1.5 GB?

As far as I understand, it's not about data but solely about address space. So even on Efika 5200B with only 128 MiB RAM, the 1.5 to 2.0 GiB address space range is used for PCI etc.

No. From a MorphOS perspective, there's no difference between having 1.5 GiB and 2.0 GiB physical RAM installed.

Thanks Andreas,
Good clarification.
Address ranges, not physical memory.
