There are two different models of Graphite clamshell iBooks.
Which of these two is it?
What is the hard drive capacity?
Do you have the original system CDs that came with the iBook when it was new?
Which OS 9 disc do you have?
What does the OS 9 disc say on it (as far as version is concerned)? It's a tricky thing to install it without the original system CDs.
Hope the firmware was updated before you installed OS X?
When the later iBook G3s came out with OS X and OS 9 both installed on their hard drives, the two installations resided on the same partition.
So, you don't have the original OS 9 disc to know exactly which version it is?
Here is the PDF on installing OS 9:
If that doesn't help, I would suggest posting in the OS 9 Discussions, maybe:
All good advice from Ronda.
When you mention "tried starting up with os 9 disk but. no such luck", did the OS 9 disk boot? As it was a copy, CD's from that era can fade, original CD's are pressed and do not fade.
If the OS 9 CD boots, can you see the partition you created for OS 9? If not, you might not have ticked the OS 9 box when initialising and partitioning from OS X.
