Power Macintosh G4 (PCI Graphics):
•1 Beep: No RAM is installed or detected.
•2 Beeps: Incompatible RAM types are installed (for example, both SDRAM and EDO installed).
•3 Beeps: No RAM banks passed memory testing.
•4 or 5 Beeps: Bad checksum for the remainder of the boot ROM block. The ROM is bad and probably cannot be fixed.
