The TF530 board is a little odd in that it is 32bit ram that lives in the Z2 autoconfig space. Reason for this is that doing Z3 needs 8 more address lines which means a bigger CPLD. It will need a firmware update to let it give up the autoconfig space after the ram is configured... After that it should play ok with "well behaved" autoconfig cards. Unfortunately some cards like the Kipper2k one (he didnt design the firmware) seem to hard code their RAM at $200000 and just turn it on when poked by autoconfig.. these RAM board will not work unfortunately because the OS will expect them to appear at $400000.

EDIT: I have considered doing a patch of the kipper2k RAM firmware to make it play nicer with the TF530 but i havent had time.
