try zapping pram

apple-option-p-r at startup, you will hear a few startup chimes. Se if that does the trick

No i tried every-thing zapping pram
resetting the Cuda button ., removing the battery for one hour..

Tried these commando's in the open firmware ;

bye ( commando for leaving the open firmware )

reset-all

boot-mac ( boots in OS 10.2 )

shut-down

reset-nvram

-boot up from cd
-run first aid

if it doesn't help:
-archive and restore

have you got the latest firmware update? check apple.com for update for your mac

for example http://docs.info.apple.com/article....howSurvey=false&sessionID=anonymous|165964367

dont know if this is the right one but have a look around
