10: references the MMU chip to set memory size. This is patched to the

12: is not needed (as yet). We also patch DMA devices and Hard Drives.

15: real STfm. These were for the STe machine ONLY. They access the
16: DMA/Microwire addresses on boot-up which (correctly) cause a
17: bus-error on Hatari as they would in a real STfm. If a user tries
18: to select any of these images we bring up an error. */
