8500 Dead - What I've done - What I need to do? |

My souped-up 8500 (xlr8-400mhz G4) seemed to be OK when I loaded XPFO 2.2.2 and restarted with the Jaguar CD, but it froze. When I attempted a restart - OUCH - a flashing icon. I've done what everyone suggests: Zap the Pram, OS9-CD, remove the battery, even more. It won't recognize any of the internal hardware, CD, SCSI drives, etc and wants to reformat them. I removed the two HD's and put them and the G4 into an 8600 I've got and viola - good to go. So how do I "restore" my 8500. It will start up in OS8 CD in a external CDRW drive, but it won't see the internal SCSI drives. Frustrated 8500 user. |

Thank you all who assisted! My 8500 is back after its first, then second, then third Death. It was necessary to replace the processor with the original 120mhz 604 chip to get a restart on internal drives. Tried XPOST twice again (god I'm either stupid or brave) and it died on restart both times. It appears to be an issue with the SCSI drives. Both are pretty old and NOT formatted with Apple drivers. I'm going to try a brand new 10k cheetah that has been formatted with apple tools into two partitions - One OS9 and one OSX. We'll see....thanks, Stephen |

This has happened to me 2 times now. you have to zap the pram (keyboard thenn the pram restore disk) like 50 billion times then it just randomly starts. after it starts once (off a hard drive) you find nothing wrong with your drives and it works fine from then on.(i just did it today installing jag) my system: Umax J700(8500 i think) Sonnet G4 400 408mb ram ATI radeon mac eddition Firewire usb combo card external firewire HD and CDRW |

On the OS8 CD, in utilities I think, there should be a disc image of a boot floppy. The XLR8 software CD also has a disc image. These will boot the machine if everything else fails. You will most likely need another mac to to make boot floppys from the disc images though. You could try booting from your CD and inserting a floppy to see if it is recognized. If so then that is a good sign. You can then copy the contents of the disc image to your floppy disc and restart. You might also have to pull out your PCI cards and reinstall the original processor if you have it. One way or another a boot floppy should work. I had to do that a few times after installing a Sonnet G4 800 into my Power Tower Pro. |

Marcush. Yes, I'm running the same HD's from the 8500 on the 8600 with the same G4 card. What "Boot Floppy" do I make? Just a naked system and Startup Control Panel? I made a new HD with only the System 9.1 on it so that nothing gets corrupted, but it won't access it either. Yes, all the cables are fine as I can see them with software and it asked if I wish to Initialize them. Obviously didn't want to do that with my good HDs. |

Your NVRAM is probably corrupted. If you have access to another mac you can fix this by booting with a OS 8.6 boot floppy or the XLR8 restore disk image that comes on the XLR8 software CD. |

Sorry, I should be more clear. Make the boot floppy on another mac if you have one handy or access to one then boot with the restore floppy in your 8500. |

boot up with 9.1 in the external CD drive. You can also install system software onto the drives in your G4 and then move them back. CHeck the internal SCSI cable and make sure it's undamaged and connected. Good Luck. |
