I can't get classic to work or start on 10.4.11. I have an OS 9.1 install disk, but can't get my iBook to start from it or install classic from it. Any help? Thanks!
Ibook, Mac OS X (10.4.2)
Some OS9 Discs are machine specific, is there any defining text or numbers on the Disc?
Does Disc Utility in 10.4.11 show that OS9 drivers are installed on the drive?
Which exact model iBook? Some cannot boot to OS9 at all so if this is a retail OS9 installer it won't boot the computer.
Here is a list of Macs that can only boot with OS X: http://support.apple.com/kb/HT2321

Upgrade to Leopard
Those wishing to upgrade to Leopard should be aware that install disks can be expensive unless you contact Apple. Details: http://lowendmac.com/deals/best-os-x-leopard-prices.html Standard Leopard installers impose several hardware limitations including speed and RAM size but all these restrictions can be overcome. Google for details. Leopard works well at 500 MHz with 1 GB of RAM and many happy users have less than this.
Upgrade beyond Leopard
OSs beyond OS X 10.5.8 require an Intel processor. If in doubt check this: Click the apple at the top left of your screen and select 'About this Mac'. This will give you your OS number. Then click 'More Info' to see which processor you have. If it says PowerPC you cannot upgrade to Snow Leopard and above. If you have an Intel Mac it is well worth upgrading to Snow Leopard now and then considering other options after that. You can buy Snow Leopard here: http://store.apple.com/us/product/MC573Z/A

Important
Check that your Mac complies with any requirements. If you are not in the US you should use the Change Country link at the bottom of Apple pages.
