| Quadra 950 -- system quirks & bus errors |
Posted by: ktkm on 2021-08-17 01:55:17
Hello,
I have a Quadra 950, with a SCSI2SD version 6, set up for four SCSI HD devices at 2 GB each (ID 0, 1, 2 and 3).
After installing A/UX on SCSI ID 1 using the partition map and the guidance from the A/UX Server Penelope, I have some trouble installing and using System 7.5.3 (only with Open Transport), System 7.5.5 and System 7.6/7.6.1. However, System 7.1.1 (ID 2) and 8.1 (ID 3) are working just as anticipated, except they were installed before A/UX.
Symptoms:
7.5.3 (with Open Transport) -- ’Bus Error’ at boot (with or without Extensions off).
7.5.5 -- ’Bus Error’ at boot (with or without Extensions off).
7.6/7.6.1 -- Re-builds the desktop at every boot, and all the icons are gone (except for folders), even when booting from CD.
What is going on? |

Looks like a damaged SD Card to me, but maybe I'm missing something. That or the drivers partition was damaged by some disk util. |

Agreed. Try a different SD card. That sounds like critical bits of parts of your SD card aren't behaving themselves. |

Good input!
I have tried a couple of drivers, but no difference in behaviour.
I’m gonna try a new SD-Card. Next, I’ll remove the A/UX partitions just to see what happens. |

You don’t happen to have the WGS PDS card in there?
That one doesn’t really play well with anything newer than 7.1. (didn’t try 8.1 though so far) |

You don’t happen to have the WGS PDS card in there? No PDS card, but a WGS card would be fun to have. I’m running tests in HDT 2.0 right at this moment and ID 0 just failed! So, there is definitely something going on with SD or SCSI2SD card. I’ll have to dig deeper. |

I finally got around to do some more testing, and it seems as if my SCSI2SD 6 2020c has some issues regarding the stock SCSI-bus in the Quadra 950? It worked without a hitch together with a Jackhammer, but since I wanted to Install A/UX, I had to choose between the Jackhammer and Apple CD 300. But, of course, everything works better after installing a SCSI2SD 5.1. |

Interesting. I have an earlier v6 in mine and have not had any trouble. A regression? |
