Thank you for your help.
Before your mail, I tried to re-install the ibook with an other
partitioning...
I selected "Removes all partitions and creates default partitions" ...
With this option, I get a F9 system with no swap problem !
Now it works ! :)
About my previous swap problem, there are 2 options:
- I made a bad personnal partitioning... possible, but I don't know why
and I did not get any anaconda warning/error...
- Anaconda and/or F9 have a bug on PPC when using personal partitioning...
(I installed 3 times F9 on this ibook with personal partitioning and 3
times I get this swap problem...)
