Leopard install freezes up on g4

[Thee]

I have an ibook Power pc g4 with 1.25gig of ram and 10.3.9 os.

I want to change the os to Leopard 10.5 and can get as far as clicking on the icon to install...waiting for the machine to reboot ...and that is all I do....WAIT

The machine shows a spinning wheel and clunks and clicks while the disk is being read.

after 20 minutes of this all goes quite but the little spinning wheel keeps spinning...

Nothing else happens.

I have tried to hold down the c key
the option key
and just did a plain old reboot with the disk in the drive...all to no avail.

After looking around for quite some time I thought I would ask for help...

Help?

Does your G4 have a processor speed of at least 867Mhz? If not, it is not compatible.

I'm assuming you are using a retail leopard disk for your iBook.

yes it does.

I forgot to mention it is a 1.33 ghz ppc g4

Maybe reset the open firmware and the pRAM. Go from there.

yes it is a retail version 10.5

everything I have read has said this would work but it is haunted or something

I did the pram ( i think i did anyway ) by holding down the apple, option, p and r keys until it restarted...
I dont know about resetting the open firmware though

Try resetting the PRAM/PMU then try to reinstall

With the computer off, or after a restart..
Hold down Command + Option + O + F

When the white Open Firmware screen loads up,

type in: reset-nvram

then: set-defaults

then: reset-all

Done...
Restarted with disk in drive.
got the spinning wheel indicator.
and nothing else.

I guess at this point I'd verify the disc is good. But how you accomplish that may be more difficult then the previous steps. Got a mac friend?

Does the optical drive work okay with other discs?

here is some good news....

According to MacTracker the highest OS for an iBook Power PC is OS 10.4+

Thanks for all your very quick responses.
