Dead 7600/120 |

I tried installing Jaguar on a 7600/120 with 128 megs ram, one 2 gig internal and a secondary 8 gig internal drives. It also has a PowerLogix G4/450 upgrade card. After installing XPostFacto and attempting to boot from the Jaguar CD, the computer would not boot properly I tried using other startup disks and the computer won't boot from them either. It seems to be dead, It wants to power up, but all it does is power on the monitor for about 2 secs and then back to limbo. Any ideas from anyone would be appreciated, I'm basically at the point where even if I can never use OS X with this machine I wouldn't care, I just need it running. |

I've encountered the "black screen of death" many times before (as have many others according to previous posts) usually due to an imcompatible PCI card (adding a G4 makes it even trickier) and have managed to escape most every time with one or more startup key strokes. so, restart your computer and immediately after the chime press: C (to start up from a CD), or; OPTION (to start up from the OS9 folder), or; CMD-OPTION-SHIFT-DELETE (to start from a partition other than the one set for startup) hope one of those helps for you. |

Try using an OS 9.1 install CD to start up with. If you have zapped the pram and it still doesn't boot try putting your original CPU back in. The cuda button is right in front of the processer slot. Then try booting up. If you can get it to boot off the CD you can set the start up disk to one of your OS 9 disks. If you are using a Video card you can remove it and try the on board video. Just make sure that you still have video ram installed. |

Actually I did try all those suggestions, I have tried disconnecting both the drives and trying them one by one, I have disconnected all the peripherals and I even cut all the power and took out the battery overnight, I don't know where the CUDA button is or even if the computer has one? Maybe if someone could tell me where it is I could try that. I have tried zapping the PRAM and after the third time it still stays dead. I would like to know why that is and why I can't just reformat and start from scratch? Did XPostFacto software do something to the motherboard? Thanx. |

Try zapping the PRAM. you should have gotten a PRAM restore disk with your G4 upgrade card. just insert it at start up. if that does not work try the keystroke (i think its command option P R(i not 100% on that but its some combination of the command option control keys with PR) hold the keys for three chimes. after that your computer wont start up you need to use that PRAM restore disk again because it changes something in the pram to let you use the G4. |
