Hi,
try
http://www.amiga-hardware.com/drivers/A500_Accelerators/mtec020and030.dmsIt includes two AddMem-tools. "Add32Bit" and "Add32Bit_special".
They add the memory if it's not set to autoconfig and shows
the memory adresses and size.
The "special"-version makes it reset proof.
AFAIR there's a tool on the disc which can change the adressmask of the partitions to not use DMA to 32Bit.
