What have I done?? - DEFAULT CATCH!

[jem71]

What have I done now?? On restart I get a white screen with....

DEAFULT CATCH! code=fffffff6 at ....[lots more other codes]
Apple Powerbook 3,2 4.1.8f5 BootROM

Welcome to Open Firmware.

I then have to type mac-boot to get it to find the system disk.
Can anyone help me get rid of this screen???

It came after I was going to re-install system and restarted with installer disk, I had to abort but didnt do any installing, basically didnt touch anything and now this screen at startup plagues me... Can anyone help??

Thanks
Jeremy

I think I may have figured it out - a usb hub was causing the trouble...
