Sucess! I managed to start IDE from Harddisk as part of the original 5.3-installation:

via command monitor:

Code:

boot -f dksc(1,6,8)sashIP17

and then:

Code:

/stand/ide

after running an io test, which includes VME:

Code:

io test pass, pass count = 20, skip count = 10

(10 skips due to "Disk Write Mode is OFF".)

So I get no VME-bus errors.

---

I installed the MMI-210 ("Vigra") board in VME-slot 1. Then in slot 2, whilst jumpering the IACK and BG jumpers of slot 1, leaving open the IACK/BG jumpers in slots 2-4. In both cases I get in HINV only:

Code:

VME bus: adapter 0

Since I know that the VME bus is working now, there are 2 possibilities: IACK/BG is still not jumpered correctly and/or the Vigra board itself has to be jumpered another way, of which there is no documentation.
