Notes
does not support DMA to its 32 bit RAM – DMAfix solves this
after a reboot, DMA into Zorro II memory larger than 512 bytes causes the machine to hang, this affects the A2091 but not the GVP Series II – DMAfix helps here too
68000 fallback mode – the software can switch from 68030 to 68000 but cannot switch back, the machine has to be switched off
memory is not available in fallback mode
