Re: VAX 4000-200 in BA215 chassis. Will NetBSD support the built-in DSSI disks if I install a KFQSA?

[James Robinson <jmr13031%gmail.com@localhost>]

sorry about the split e-mail. (google crashed on me)

My DSSI bus is as follows:

DSSI-ID          Device

7                     SHAC DSSI controller

6                     KFQSA

1                     RF72

0                     RF73

I also just booted it up and I am running NetBSD 9.1. I can send you a copy to try on your systems as I had to MOP boot  it to get it to see my devices. 

If I remember correctly it was an issue with the serial device and the amount of memory I had on the q-bus.

It has been about 4 years.....

Hi Thomas,

How far did you get?

It has been a while since I have hopped on the port-vax mailing list, and I was hoping that you got the answers you were looking for.

I have a VAX 4000-200 with the KFQSA controller looped into the onboard DSSI bus and it is booting my 3 local drives just fine.

I had to change the controller ID for the SHAC to 6 as you can't have the onboard and the KFQSA at the same address. But I have it booting NetBSD 9.0 and I am trying to build 10.0 release now.

I can send pictures of the setup if you need them. 

Here is my DSSI bus setup.

I know NetBSD does NOT support the SHAC DSSI controller on the KA660
CPU cards, but if I take a KFQSA controller from one of my other VAX,
can the chassis "internal" DSSI disks be disconnected and then
re-connected to the KFQSA card bypassing the SHAC chips on the CPU
card?

I've got a couple of VAX 4000-200 boxes, but they only run OpenVMS
now, but I'd like to install NetBSD on them.

has anyone tried this?
Happy 2024 everyone,
