I have a g4 400 that was upped to a 1.6 aftermarket. I need to boot
in
OS9 and somewhere along the line it stopped booting in 9 all

So, what is the latest version of OSX that will allow me to boot in
OS9? I can't use the program I need (cubase 5.1) in classic mode.
Thank you SOOOOOO MUCH!

The version of OSX doesn't affect OS 9 booting.  (Classic doesn't work,
starting with Leopard 10.5)
If you reformatted the drive and didn't choose the OS 9 driver option,
it won't boot OS 9.  Select the drive in Disk Utility and Get Info on
it.
Some CPU upgrades need a firmware update to allow OS 9 booting.  Look
at the documentation for the upgrade.

I upgraded my Dual 1GHz G4 to 1.8GHz with a PowerLogic upgrade.  As part
of that upgrade, I had to flash new firmware and add a special extension
to my MacOS 9 System>Extensions Folder to get it to boot OS 9 with 1
CPU.  Otherwise it would hang.  It also wouldn't run Classic without
this extension.

Check your disk to be sure you formatted it to have the OS 9 drivers.  
If not, you'll need to backup, reformat, and restore to regain OS 9
booting.

If Classic doesn't run, chances are you're stuck unless you revert to
the 400MHz CPU.  This is one of the reasons I hesitated to buy the
aftermarket CPU accelerator.  In the last system, my OS 9 boot became so
unstable that I had to really be careful of updates.

Good luck.

The speed upgrade was fine when I first put it all together. The
problem happened after I tried to install osx10.5 and it didn't work.
I had to revert back and nothing worked after that. At least I am
smart enough to have kept all of my files on drives OTHER then the
boot drives - I learned that the hard way a while back:-)

So I can must spend a day installing all the software (programs
included) again.... Oh Joy! At least I know where I went wrong and how
to fix it. I've been told now that 10.4.10 will work fine - hope
that's all I need to make this work again.

I have about 20K in recording software that I bought for the old OS9
system and to upgrade it all would be more then I could handle. I
bought some of the stuff for OSX and it never worked as good as the
old stuff so I'm clinging for life to a really old system. When this
dies I don't know what I will do.

Thanks for all your help
