Your start up bong should be a single smooth tone. If it is a "melody" of any kind, it is not a startup bong, but rather chimes of doom. The melody will tell you what may be the problem. The first thing is to check the PRAM battery. Many Macs will not start properly with a dead battery. If it is dead, Radio Shack stocks all 3 kinds used in Macs (but ironically, standard PC CMOS batteries are special order). I don't recall if the Performa 47x used the square 4.5 volt, or the 1/2 AA 3.6 volt. I think it might be the 1/2 AA, but either way, it will be pretty obvious when looking at the logic board. Also, press the CUDA button on the logic board (again, I don't recall off the top of my head if the 47x has one, but I think it does). This will be a small red button on the logic board. I seem to recall on the 47x it was either near the ports on the back of the board, or near the front by the floppy and HD connections. But again, it might not be there at all. The CUDA button will do a deep hardware reset, this will clear any screwed up hardware settings it might have (and is usually recommended to do after changing PRAM batteries, or adding or removing cards). Finally, if none of that works, disconnect the HD and floppy. You should get at the very least when no drives are connected, a grey screen with a disk with flashing question mark. If THAT doesn't work... do you have access to another Mac? Can you make a known good bootable floppy disk? (you can download a 7.5 disk tools image (reconnected drive that is), and try to boot from it. If your system is working, but the monitor is dead, you will head the Mac doing a bunch of accessing of the floppy drive as it boots (They will boot fine with no monitor attached). But with all this, I suspect the problem will be a bad PRAM battery, or a need to press the CUDA button. -chris <http://www.mythtech.net>
