Hello, I recently upgraded my PowerBook Pismo to G4 500mhz, and with 512MB of RAM. I have installed Sorbet Leopard but it gives this error at boot.

Is there a solution or is it incompatible?

I think max OS officially for Pismos is Tiger ie. 10.4.x, the Sorbet is a Leopard-variation ie. 10.5. There are some rumors that Pismo could run Leopard but it needs some third party software (and the G4 update you have) to do it. I have no knowledge of what software is needed. But out of the box it might not work like you are finding out. You could find a solution though so keep on looking.

You could try Shuriken if you want readily tuned Tiger.

There is a firmware update for the Pismo that should solve it. I don’t remember what it is off hand but if you search you should be able to find it. I had the same issue. The update fixed it.

Also, you can add 1gb of ram to the Pismo despite Apple’s official specs.

Almost forgot, after you successfully install Leopard, you should add the Rage 128 driver. It’s available on Macintosh Garden on the Sorbet Leopard page.

Even with the 128 patch you will still have some glitches. The graphics seems to be the greatest limitation for G4 upgraded Pismo’s.

Thanks!! I did a quick search for "Pismo firmware Sorbet Leopard" on Google and I didn't find anything. Where can I find that firmware? Does anyone have it available?

I'm going to download the Ati RAge drivers, thanks a lot for the detail.

Delete the Sorbet from your search. Sorbet only couple of years old. What you are looking for was something that was released 20 something years ago by somebody (who?).

So, try to search for info on how to install Leopard to Powerbook Pismo (or whatever version number it has).

Sorry, I explained myself badly in the "edit". I downloaded the firmware that I linked, installed it and now Sorbet Leopard works, it has installed the "f5".

Thanks for your help.
