From: E Hoffman <[EMAIL PROTECTED]> Date: 06 May 2005 17:02:44 -0400 Hi Robert,
Thanks for your reply. Here's how my S900 is set up:
1 GB RAM. G4 450 Mhz processor USB card in bottom PCI slot. OS 9.1 on internal SCSI OS 9.2.2 on internal IDE w/ ATA card in top PCI slot.
Before the black screen problem appeared I had selected the CD-ROM as the startup drive in the control panel. I did this because I wanted to be assured of being able to boot from the Mac Install CD. I turned the computer off and relocated the ATA card from the top PCI slot to the one directly below the video card. When I powered up again I had no video. The chime did play and I heard activity from the SCSI drive and the CD-ROM light flashed but I couldn't get anything to boot, but then the screen was black so I couldn't tell what was happening (if anything). Even though your suggestion of disconnecting power to the internal SCSI and bypassing it had to do w/ OS X problems, I think I'll try that anyway, because at the time I chose the CD-ROM as the startup drive, the SCSI was the startup drive. I've only been holding down the key combination to Zap the PRAM about a minute and a half, maybe two and then given up. But I will do as you (and also Paul C.) suggested and hold the keys down for at least five minutes and see if I can get the chimes to repeat.

At last some clues that may lead to an answer. Was the Mac OS install disk an OSX disk?? You can not install OSX by choosing it in the startup control panel on an old world Mac. This leads to the classic "Black screen of death" which if it was an OSX disk you now have ! You said you removed the battery . Was the machine unplugged from the wall plug? This point is nearly always missed for some reason. Jeff's uber pram zap should also work but needs to be done from off not a restart for "Black screen of death" Removing the battery and unplugging and using the cuda button is pretty much fool pruff. I'm going to go out on a limb here and state that most motherboard replacements are a waste of time and money. Unless the motherboard is physically damaged or you smell smoke it's likely fine. If it's not an OSX cd in the drive well we may have to re-think this. Most Cd drives have a pin hole which lets you use a paper clip to force the drive open so you can remove the disk. Let us know how this goes. Will S
