Immediately after the start-up sound plays is the time to hold the key you want to hold. I'd personally go with Option, as it'll let you make sure you're doing what you want.

Oh, and to add info without making a new post, just click Edit in the lower right.

Leopard requires a 867 MHz processor, and it sounds like you were using a Leopard disc from an Intel Mac, not a retail version.

It would help if we knew what kind of PowerMac it is.

You definately need more memory, and you can always upgrade the processor if you wish.

Leopard requires a 867 MHz processor...

Did he mean Leopard? I was under the impression that he actually meant Panther... When people don't know the order, it's hard to tell...

Cheetah, Puma, Jaguar, Panther, Tiger, Leopard...

I can rattle them off like that *snap*... I'm such an AppleGeek.

mac os X 10.2.8
Machine speed 400 mhz

Well, Panther itself is a fine upgrade from Jaguar, but you won't be able to get it to Leopard without hacking, anyway. Even then, unless you have über RAM, it'll run too slowly to be usable.

400Mhz does not a Leopard make.

its ok i jsut want panther on it for now ahhh lolol

ok i think i know the problem...theres something wrong with my cd rom i switched it out for another one and nothing....i was wondering if theres a way to boot from a flash drive?

Mar 6, 2008, 07:35 PM
No, you aren't going to be able to boot from a flash drive. Dude, put the old drive back in if it's a problem.

Is it an AGP or PCI-based G4? That affects the options you can upgrade it with (even OS... if it's a PCI-based G4, you can't install Leopard.. assuming you even care to).

I'd recommend putting in another 512 MB of RAM in that... 512 MB often isn't enough when you get to Panther, and especially Tiger, though to be honest, 768 MB works all right (though why bother.. 512s are cheap).

You cannot boot from USB. If you were to have an external DVD drive, that might help, but it must be Firewire. Try a different keyboard (maybe that is the problem). Also, just to make sure, is it a greyish/purpleish machine or a blue machine?

the exact computer without the cool monitor

im good with windows based pcs....this mac things a whole new world for me tho lol

i dont no what else to do here it wont even read the disk...i checked all the wire connections and switched the drive...everything...

Mar 6, 2008, 08:32 PM
ok i figured out the problem....its something to do with the drive...when i turn on the computer it works fine... but...when it finally gets booted up if i try to open the drive or do anything with it its not responsive...the green light doesnt light up nothing...anyideas?

Apple actively mounts discs, so you have to either use the eject key on the keyboard or drag the image on the desktop to the trash to eject a disc. If you are already in Jaguar, use the Startup Disk Preference pane and see if that will allow you to select the Panther Disc as your startup disc. If it does, do it, then restart. You should then be able to install. Also, you may need a DVD drive to use the Panther Disc (not sure about that).

You'll only see it if there is a disc in it. Go to the Apple Menu and select "About this Mac" then more info. You'll get a screen similar to Device Manager in Windows. See if the drive appears there. If not, you should try another drive if you can. You may also need to check the jumpers on the drive. It would be best to try it in a master or cable select position without any other drives on the ribbon, and make sure the ribbon is securely attached to the logic board.
