I'm not a VME expert but since no one has replied yet I would guess that without bus termination the board may not boot. There could be other requirements specific to your board.

İ think that i should have to power +5v to STANDBY pin. İ will test next week.
When i power these pins (pins names up) harddisk is working display card is working. Only cpu is not working.

Being a hardware guy, I would advise against it. It's an accident waiting to happen.
