From: abrody@worldweb.net (Don't Panic) Subject: Type-1-FAQ-9-28-95.txt Folks, Anyone who has not heard the answer to this FAQ should read this: Why does my ... Application unexpectedly quit? Finder report a Type 1, 2, 3, or 28 error? Finder report an F-line error? Finder report a BusError (Type 1)? All four of these happen basically due to any of the following problems: Your desktop file is corrupted Your PRAM is corrupted An INIT conflict A fragmented hard drive Incompatibility with machine or system Lack of math coprocessor (usually followed by a Finder error 90) Preference file corrupts Internet connection through TurboGopher, Fetch, Telnet, Mosaic, Eudora, or other TCP/IP client application quits with a type 1 error. Solution: To uncorrupt (or rebuild) your desktop file, after the About this Macintosh screen disappears during startup, press the Apple and Option keys simultaneously. This results in the loss of file comments in the Get Info of the Finder. To uncorrupt (or ZAP) your PRAM, hit the Apple, Option, P, and R keys simulataneously when your Mac starts up. The screen will blink, and when the Mac is done loading, you will have to reset your control panels to your desired settings. Also, if you don't want AppleTalk on, zapping the PRAM turns it on. To fix the AppleTalk problem, just enter the Chooser DA, and turn it off. An INIT conflict. Extensions Manager 2.0.1 is Free and available at many sites on the Net and at Mac BBSs. It is made by Apple, and allows you to select which INITs (Extensions in System 7) are loaded. Sometimes the conflicting INIT can be loaded by itself without any problems. If you isolate the conflicting INIT, try renaming it either the last or the first name in the alphabet of INITs. Entering a space in the name puts it before the other INITs that begin with a number or alphabet character. Control keys are even earlier. Finally, all programs that do not require extensions loaded, will work fine with all extensions off. To turn off all extensions, press the SHIFT key upon startup. Conflict Catcher 3.0 by Cassady & Green (commercial) will also all this, but it has a much more sophisticated system for catching INIT conflicts. Two utilities are available commercially to fix fragmented hard drives: Speed Disk (by Norton), and DiskExpress by Alsoft (I forget who bought Alsoft, but somebody will probably reply to this FAQ mentioning who did). Turn off all your extensions except the DiskExpress control panel (if using Alsoft's product), when you do a defragmentation. For preference files that corrupt, Virex (commercial), the virus detection program can detect the individual preference file that got corrupted. There may be other software to detect corrupted preference files, but that is the only one I am aware of. Removing the preference file once isolated, will fix the problem. If none of these solutions appear to fix the problem, then you need to contact the author and tell them what System you are running, the RAM installed on your system, whether your machine has an FPU, and what machine you are using. The system can be found by selecting About This Macintosh (or About Finder) >From the Apple Menu when you are in the Finder. The RAM installed is also in that window. The author can tell you if the software is compatible with your machine. All LC machines lack FPUs (except those that have had them specifically installed). Please note, all Blackbird 68040 Powerbooks lack FPUs, even if they are not advertised as such (the exception may come with the PowerMac upgrade due later this year). In addition there are times when too much multi-tasking may cause a BusError. This is due to the fact that some machines have pathways half the size of the CPU leading to the CPU. The 68020 is a 32bit CPU, with 16bit pathways. Hence there is a logjam of information. Similarly, the PowerPC 601 and 603 processors have a 64bit processor with a 32bit Bus. Only True 68030, 68040 (Quadra AVs, some 63x, 700, 800, 900 series), and PowerPC 604s are devoid of this problem along with the FPU problem. PowerPC chips have a built in FPU, and SoftFPU for PowerMac (shareware) will make it so that programs requiring the external FPU notice the one in the PowerPC. Internet type 1 errors. Your connection was improperly setup before you attempted loading the TCP/IP client application. Connect to a registered Domain Nameserver before attempting to load any TCP/IP. If you don't know how to do this, I'd be happy to help with any MacPPP style connection for single user connections. Above all, read the documentation that comes with the software. Most of the time the author specifies what is required in the documentation. If there is no documentation use the software at your own risk. Standard disclaimers apply. Hope this helps.
