Enabling L2 cache

[Viro]

I've found out that in the hardware section in System Preferences, my L2 cache is always marked "None" by default. Even after I select 512 KB, it defaults back to "None"

Is this a problem? It doesn't seem to have any adverse effect on the system and XBench still recognises the 512 KB of L2 cache even with it set to "none".

My question is, should I worry that the L2 cache always defaults to "None"? Is this normal?

I was also wondering about this. This will essentially make the computer faster, no doubt?

Also on the same tab, there's a Nap option that is selected. Can anyone shed some light on what this does?

After running the 10.3.5 update, it seems to resolve my problem with cache not being enabled. I think it was enabled prior to the update, just that it wasn't shown.

Nap mode AFAIK is a feature of later G4 and G5 processors that allows the CPU to dynamically scale it's clock speed and perhaps turn off parts of the processor that aren't being used. This results in a much better cooler processors and lowered power consumption. Initially, some reported crashes when nap mode is enabled. I think Apple has sorted out most of the teething problems.
