I need to type this in open firmware, because my mac shows the wrong speed (500 mhz, should be 667)

set enter to ASCII character 13
set cmd to "\" /\" select-dev" & enter & "7efdc44 \" clock-frequency\" get-my-property 2drop !" & enter & "un
select-dev" & enter & "\" /cpus/PowerPC,G4@0\" select-dev" & enter & "27af4d54 \" clock-frequency\" get-my-pr
operty 2drop !" & enter & "7efdc44 \" bus-frequency\" get-my-property 2drop !" & enter & "1fbf711 \" timebase
-frequency\" get-my-property 2drop !" & enter & "unselect-dev" & enter
set cmd to quoted form of cmd

do shell script ("/usr/sbin/nvram nvramrc=" & cmd) with administrator privileges
do shell script "/usr/bin/sudo /usr/sbin/nvram use-nvramrc\\?=true"


How do I do this? I really need a detailed description

Thanks

That's AppleScript, not Open Firmware commands. (Though the 'nvram' parts do update Open Firmware settings.)

To run it, open the Script Editor application (in the AppleScript folder in the Applications folder), paste that code into the window, and click the Run button.

I hope whoever gave you this code knows what they're doing, since I am in no position to check that it will solve your problem without doing Bad Things to your Mac.

Its not an Applescript. Ive been lookin around the internet and this is an open Firmware script.

My maschine is running at 100 bus, I need it to run at 133

Thanks

Try this first and see if it works:

From the open firmware prompt.

Code:
reset-nvram
Press Return
reset-all
Press Return

Well it's not an open firmware script. I don't think open firmware can run shell commands.

Thanks for your help folks. I havnt solved the issue yet though.

I can give you some more info:

The pb TI is originally a 550/100. But I OC it to 667/133 following instructions on this site:

http://www.macbidouille.com/article.php?id=142

Everything works perfect, all my benchmarks are up by almost 30%

But my ASP shows 500/100, which is normal, according to this site. But there is a script on the OC site that I need to run to make the ASP show 667/133, but I dont know how. The script is exactly like the one I first posted

The author of the page hasnt answered me yet, so I am turning to you guys.

Thanks

I'm sorry, but that is most definitely an AppleScript. As goMac said, Open Firmware can't run shell commands (which is what the "do shell script" parts do).

Beyond that, I have no idea what you should do as I've never overclocked a Mac.

This is an AppleScript wrapper for the OpenFirmware script, which apparently does nothing but override the builtin CPU/Bus speed indicator. Don't blame me if it breaks anything, though.

All this does is set the "cmd" variable to the complete OpenFirmware "nvramrc" (kinda like a startup script) and then tell the "nvram" command, a user-level application, to set the actual firmware nvramrc to the value of what you assigned to "cmd".

It should ask you for your admin password when you run this.
