Amiga 4000 3.1.4 GURU 80000004/80000005/8000000B at boot
Hi all,
The following has me puzzled and confused for many months now. I have an A4000 that GURUs at boot all the time. Sometimes it takes 20+ reboots to make it to the Workbench. A4000 with 2MB chip and 16MB fast original 3.1.4 ROMs WarpEngine 4040 SCSI2SD v5.1 with two 1GB "disks" (FFS) Ariadne2 network card with Roadshow IP stack (1.13) Install is a clean 3.1.4 install, nothing weird. Sometimes the machine will go straight to Workbench without issues. If it does that it runs quite stable for many hours. If not then forget about it, it will play bad for many boots to come. I've added the 68040.library from both the WarpEngine disk as well as the library from Mu680x0Libs.lha from Aminet (Babel's version) to LIBS, same result. Any ideas what I'm doing wrong? |

Hi all,
Thank you for having a look. I'n done a clean install of 3.1.4 with the same result. The machine is now without any cards. 68040.library from WarpEngine disk: version 37.30 43888 bytes 68040.library from Mu680x0Libs.lha: version 37.30 43924 bytes S:Startup-Sequence (stock 3.1.4), see screenshots attached. |

When taking version numbers of the libs, just to be sure, say:
version data:warpsoftware/libs/68040.library file and version data:mu680x0libs/libs/68040.library file |

If you’re using mmulibs then you need 680x0.library as well as the cpu library

Err, sorry, no. It is an optional library with some features to control the FPU and its exception processing, but it is certainly not required for 3.1.4. What is required, though, is the mmu.library in LIBS:

OK this has been driving me crazy for a very long time and I'm really happy with your help!
I've gone back to basics. Formatted drive again and reinstalled the machine using 3.1.4 without any boards installed. Then ran a memory test (Memcheck12), no errors. Machine still has only the WarpEngine 4040 with 128MB and a SCSI2SD5.1. Then looked through all my install disks and tried all different 68040 libraries that I could find. Funnily, the last one seems to run stable. At least the 20 or so cold and warm boots have not failed a single time, and I have yet to see a GURU. See screenshot... I've taken "68040new.library" from the Phase5 archives and used that as "68040.library" on the machine. |

More weirdness... I have an IDE Zip drive lying around that I want to use in this machine for file transfer and backups. However, as soon as I connect it to the IDE port the GURUs return. Tried installing IDEfix97 but same result...

OK, quick followup to this GURU weirdness.
I spent the Saturday disassembling the machine and replacing the parts one by one. Swapped the WarpEngine 4040 for the A3640 (recapped etc.), moved the SCSI2SD to my trusted A2091, then swapped the complete motherboard for my spare A4000D motherboard (yes, I have one, recapped and all). No change! The only thing left (besides PSU and floppy) was the SCSI2SD. No... would it, really? I decided to wipe it clean. Connected it to my machine, launched the SCSI2SD tool and killed all IDs on it. Recreated them with different sizes (512MB for ID1 and 2GB for ID1). Connected to the Amiga again, ran HDToolbox, read the disk parameters and reinstalled. No crashes anymore Tried the different 040 libraries, including Thomas' version - works brilliantly. Swapped the A3640 for the WarpEngine, all fine. Runs super fast, no weird crashes... I still expect to see the GURU at startup but it boots straight into my plain 3.1 install... Why? I'm not a disk expert but maybe the RDB on the disk contained some form of filesystem version that made the machine crash? I'm happy now because I spent a weekend but got my A4000D back to a usable state! |
