Don't forget, amiga 2000 was limited to 9mb, starting with 1mem chip ram and 8 fast ram, when you added other boards, that required to be in that space...it would just not see the other mem....
You had to add mem above the 9mb space (like the megachip adding 2mb of chip)
and accelerators that added mem above the mail space.

I am sure he knows that, the VXL is an accelerator with 32bit RAM which should not conflict with the 16bit ZorroII 8mb RAM limit.  Re-read his post and you will see that I think.

It's not the zorro space...it's the auto- config space and
Actually, all accellerators of that era tried first to fit into auto-config space.

My 2620 and my 2630 each had 4mb of fast ram at 32bit when I added my Picasso card it lost ram...
happened to folks who tried to add the 2megs on the 2091 mem and scsi card
The 9 mem limit really played havoc on the bridgeboard folks who were limited to 6megs.

I fixed these problems for tens of LAAUG AND AUGLB AND SACC users when they were upgrading.
