Every GVP board I've ever had autoconfigs all of the accelerator memory, it's built into the faastrom on the board. The maximum on that particular board is 16mb if it has 4 of the 4mb gvp 64-pin simms. The maximum ram installable in a so equipped A2000 would be 24 if you installed an 8mb ZII ram board like an 8-up or GVP HC+8 board fully populated. This of course is going to eat up all of the ZII card autoconfig space so a bridgeboard or graphics card is going to conflict. Better to install only 6Mb of ZII memory on such a card.
