Old machine, yeah, PPC... I know about disabling L3 using CHUD hwprefs, but the computer needs to succeed booting to get there in the first place. I've always wanted to kill L3 cache at the hardware level on the CPU card so that it boots starting with L3 cache Off instead of always On (in order to overclock CPU higher since L3 cache speed is synchronous with CPU core speed). I doubt Firmware programming would help because not even Firmware begins executing soon enough to overclock CPU core faster than the L3 chips can be pushed.
Got a way to make the CPU card power up without L3?? I tried disconnecting power to the cache chips, but then it didn't boot at all, and I reconnected power.
Any help will be apprecited.
I didn't find the right solution from the Internet.
