- In the manual for the A530, there is talk of jumpers which control
- the 'emulation' of MMU functionality to allow the ROM to be shadowed
- into 32bit ram. To use the MMU '030, it talks of having to short
- (or close?) a set of jumpers on the motherboard, which disables the
- on-board 'GVP MMU' (such that it is ...). Could this explain your
- problems with setcpu not working properly?
