Failed reboot into OS9, now can't boot at all |

System: PTP 200 w/ 192MB RAM, 2 SCSI drives(OSX, OS9.1), Sonnet G4/450. I needed to boot in OS9(separate harddrive) so I used the Startup Disk app. This has worked before. However, this time when I try to boot up into OS9 it appears that it was successful but after mounting the drives to the desktop the watch cursor appears and spins very rapidly. The machine is basically locked up at this point. The only successfull boot that I can do is using a OS8 boot floppy. I thought that my System Folder may have become "unblessed" so I dragged the System and Finder files out of the System Folder an back in. Didn't work. The fast watch cursor even happened when I tried to boot of the OS9 install CD. I have tried the following: 1. Attempt to boot into OS9 on OS9 drive and OSX drive 2. Zapping the PRAM 3. CUDA switch 4. Re-blessing the system folder. Since I can't boot into OS9, I also can't boot back into OSX. Any ideas? To make matters worse I also just purchashed a 120 GB IDE drive, and 256MB RAM plus Sonnet ATA100 card from OWC. |

Here are a couple of ideas. I remember that I used to get a problem occasionally where, at boot time, the watch cursor would appear and disappear very quickly over and over again forever. That was solved by deleting a preference file, but unfortunately I can't remember which one :-) I suppose you could boot with your Mac OS 8 floppy, rename your Preferences folder (in your System Folder) and then try to reboot into Mac OS 9 to see if that helps. It seems possible that the Finder is choking on some problem with one of your hard drives. The fact that the problem happens even when you boot from a CD suggests this. If that is the case, then what might work is booting without mounting the hard drive, and the running Disk First Aid, or DiskWarrior, or something of that kind to see if it can find a problem and fix it. The easiest way to do this is with a DiskWarrior CD. It comes with an extension that, if you hold down the "d" key, will ask before mounting any drives. That way, you can leave the drives unmounted, and use a utility to diagnose the problem. |

I haven't installed anything new yet. The hardware is the same as it was when I originally installed OSX last week. I did upgrade from OSX 10.1 to 10.1.5 after my last successful boot to OS9, however. I haven't tested the battery. I did remove it overnight to see if that would help but it didn't. I haven't disconnected everything but I did disconnect the OS X drive but it didn't help. The only difference that I know of is that I moved all the SCSI devices to the external bus to get my CDRW drive to work for the OSX install and moved them back to the internal bus at a later point. I believe that I booted into OS9 after moving the SCSI devices back to the internal bus. |

Need a new PRAM battery? If it is weak, CUDA/PRAM resets may not work. Disconnect everything you don't need to boot into 9 (eg OS X drive, PCI cards ) etc. Have you put in the new RAM yet? |
