A while back I sent some instructions that came with Rempel's old world support software. It describes what happens when you do a motherboard reset.
I was totally freaking out last Friday when I was stuck in that loop of dark screen, one startup chime on a keyboard induced restart, and no ability to get to anything PERIOD, and not even the ability to zap the PRAM. Thank the stars above that I remembered Ryan's advice. I couldn't quite remember the specifics and I could not get to my computer to read the file. It was only using motherboard reset that got me back to where I could zap the pram and bring everything back to life. Man, I was depressed thinking I had really done it then, and even made a trip to CompUSA thinking I would have to be considering another computer. I knew the data was safe and I could just move hard drives, but still the hassle and expense of all that was very disheartening. I was not sure if I had somehow scrambled the motherboard firmware into oblivion. Just for good measure I'll go ahead and send those instructions here again. It just might help someone when they need it the most. `````````````````` Problems using the Startup Disk in OS 9 It is particularly important to use System Disk, and not Startup Disk, to choose the OS X partition to boot from. I have had reports that the OS 9.1 Startup Disk control panel may cause problems if you use it to boot from an OS X partition on an unsupported machine. Several users have done this and been unable to boot. Rebooting with the option key down has not returned them to booting in OS 9, as it should. Zapping the parameter RAM has also been unsuccessful for them. Booting a CD with the "c" key down also didn't work. Should this problem occur to you, it appears that it can be solved with the following steps: 1. Unplug the system from the wall. 2. Remove the battery. 3. Press the Cuda reset button for 30 sec. (It is usually near the processor slot) 4. Put the system back together. Make sure you orient the battery as it was before. What this accomplishes is a very thorough reset of the NVRAM (more thorough than the ordinary option-p-r to zap the parameter ram at startup). If this doesn't work, you could try steps 1 and 2, and then leave the battery out for an hour before replacing it. >Thanks to Larry Coltharp writing on Tue, 27 Aug 2002 17:39:33 -0400 for >the following comment: > >>I would say, shut down and pull the old card and try rebooting.
