OS9.04 stops with starting before ext load


Hi, my OSX runs fine on a separat partition on my G4-450, but when i try to run os9 which is on my first partition the os9 starup screen appears the blue bar starts filling up for half a cm and then the syatem seems to quit. The icon also go out of the dock
I am runnig the international version of 9.04 with 128mb ram
Any one with this problem or an idea what is wrong?

thanks and regards
