Lion reset pram?

[malcolmx99]

Dear all,
Have upgraded to Lion about a month or so, it's often beach ball and frozen of the OS have made me decide if I should Format and do a clean install of the OS. However, that would be my last resort, as I would like to try some more things before I go that far.
Currently, I have done the repair permissions, have more than 50% of hard disk of empty space.
What to do a Reset the PRAM (boot with Command-Option-P-R), but when I boot it up pressing the keys, it goes into disk utility. Does Lion have Reset PRAM?
Can I Reset Nonvolatile Firmware (boot with Command-Option-O-F and type "reset-nvram" at the command prompt) ??

Thanks in advance!

You can't use Open Firmware because it's not a PowerPC (cmd-opt-o-f). I do recall resetting PRAM in Lion before I whipped it and rolled back to Snow Leopard in July. As I recall, the key sequence is identical. That said, since the recovery partition is cmd-r, it's possible that having the cmd-opt-p-r keys held down is far more time sensitive than it used to be.

FWIW, Apple hasn't changed their technote on resetting PRAM/NVRAM.

Resetting the PRAM is going to do nothing to speed up your Mac when you're running it with only 15% free space according to your post in this thread.

You need to either free up more space, defrag the drive, replace your drive with a larger one or some combination of these. My standard recommendation without knowing much more about individual situations is pretty much always to get a larger drive when you hit 30% free space on your system partition. If you have an iMac, then I'd probably start considering other options for storage of your data rather than opening it up.

A format, install and restore via Time Machine would accomplish a defrag. But with 15% free space, you're still going to have slow downs in my experience. It becomes unbearable for me at 30% free space - even after a clean install and restore.
