I numbered the slots for you. I think the modules are 32 bit, the bus
must be 32 bit also. My VS 4000 VLC uses normal PS/2 modules from PC's,
but with parity and i think this really needs two at once. But the 3100
uses a little bit strange modules. DEC-specific. Looks like PS/2 but has
2 pins more.

I'm not sure, but try to put the module 3 onto place 1 and leave module
Then test again. (maybe some more times to get sure).
It it's an error, try every single module and kick out the bad one (and
hope, it's only one. 8 MB is really the minimum to efficiently boot)
Ok, i'll look in again this evening.
