| Can't Boot: DEFAULT CATCH!, Code=1800 iMac G5, struck by lightning about 2 months ago. Started having boot problems after that. It would take about 5-7 tries before it would finally boot. Intermittent crashes, freezes and lockups since then. I've suspected a corrupted disk (still gives the Happy Mac chime during power on) and have been pulling all my important files off of it (onto my new intel iMac) over the past few weeks. This morning, it won't boot for anything and gives me a constant, scrolling message: DEFAULT CATCH!, Code=1800 at %SRR0 00000000 ff845b6c %SSR1: 100000000.0200b030 The fan comes on and it just scrolls that message over and over. I tried to use my 10.5.2 disk to boot from and now it won't let me have my disk back. Any help on how I can: A: eject my OSX 10.5.2 disk? B: get this to boot so I can reformat the drive. Any help would be greatly appreciated. Thanks. patrick  |

| A. Boot while holding down the mouse button. That should eject the CD during the startup phase. If that doesn't work, try booting into open firmware and ejecting the CD that way: http://www.macosxhints.com/article.p...31210193237190 B. If you can't boot from the CD to install the operating system holding down the 'c' or 'option' key at boot, then you can try installing from another Mac via FireWire Target Disk Mode.

| El Diablo, Neither of those options worked. Anyone else got a suggestion? Am I going to have to crack open the case to get to the little manual eject hole? |

| Can't Boot: External Interrupt Hi, Found this previous post http://macosx.com/forums/mac-os-x-sy...de-1800-a.html This subject Can't Boot: DEFAULT CATCH!, Code=1800 This error message DEFAULT CATCH!, Code=1800 at %SRR0 00000000 ff845b6c %SSR1: 100000000.0200b030 I also can't boot BUT have a slightly different error message on a "white screen of death" External Interrupt at %SRR0: 00000000 ff845b6c %SSR1: 10000000.0200b030 Tried several of the suggestions in previous post but none worked - including ejecting from the cd/dvd drive. Seems like it never gets to the OS. The last part of the initial error message (including "Welcome to Open Firmware" etc) before the endless scrolling of the error message, reads Reducing System Power... Any ideas? TIA |

| Can't Boot: DEFAULT CATCH!, Code=1800 I was so relieved to find that the motherboard was dead. Problem solved! Of course, YMMV but we got a new mac mini so I can do my work instead of working at trying to find what's not working. I like it when things are broke/dead rather than just limping along and intermittently driving me nuts. Good luck, though. Maybe you'll find a fix. inquiring_mind |

My G4 just did the exact same thing.. A scrolling DEFAULT CATCH!, Code=1800 at %SRR0 00000000 ff845b6c %SSR1: 100000000.0200b030 with the fan over exerting itself. |
