A1200 32bit RAM configuration

I've been having some issues with memory being recognised. I seem to have narrowed it down to a couple of issues. The hardware is set to a standard A1200.

1. With A1200 Kickstart 3.0 (39.106), I can't get any memory recognised when added to the processor slot no matter which settings I choose.

2. With A1200 Kickstart 3.1 (40.68), memory is not recognised with the default 68EC020 configuration. If I disable 24bit addressing, emulating a full 68020, the memory appears fine. (I know that 24bit addressing limits it to 16mb, and I'm trying to add 4-8MB memory, as with real expansions.)

I'm adding it this way, as the default is to add Zorro II RAM, which didn't exist on an A1200, and is only 16bit, while the processor slot expansions were 32bit fast RAM.
