L2CacheConfig 3.1 is out — the application enables the L2 cache under Mac OS X for G3 and G4 upgrade cards. The latest version of the freeware product removes features related to Altivec and speculative processing. These features have been determined to be unnecessary with Mac OS X 10.0 or later.
“It turns out that Mac OS X enables Alivec support without my help, so I have removed Altivec support from L2CacheConfig,” developer Ryan Rempel says in a note on the product Web site. “It also turns out that Mac OS X does the correct things to safely use speculative processing, even on machines that originally shipped with a 604e processor. Speculative processing can still conceivably cause some problems very early in the boot process, but L2CacheConfig becomes active far too late to deal with that.”
To use L2CacheConfig 3.1, you’ll need (naturally) Mac OS X 10.0 or later and a G3 or G4 upgraded Mac. It’s a 256k download and can be grabbed at
Rempel’s Web site.
