G4 cube dual boot OS X and OS 9

[Mustermann]

Recently I got a Mac G4 Cube with OS 10.3 installed which is working well.

Tried to install OS 9 on a second existing partition at the same hard drive from Mac G4 Cube Recovery CD.

When starting from that (OS 9) partition it take 25s with a grey screen, then 25s with a Mac with a question mark, then booting onto OS 9.1

I installed the same on a USB stick. This stick is booting into OS 9.1 without the question mark.

Did a parameter RAM reset: Mac booted into OS X partition. When switched back same procedure as before.

OS 9 driver is installed on that partition.
Firmware is 4.1.9
Selected boot device to OS X and back to OS 9: Same procedure as before.
OS X boots without question mark.

What can I do to boot into OS9 without the Mac with question mark delay?

do you have a good PRAM battery installed?

Yes I installed a new battery before the installation.

I have had very long flashing question mark on the Cube when I had an IDE conflict between the SSD and DVD. But that would not explain Mac OS X booting quickly, would it.
