No cmos.dat saved when changing configuration.

[Scott Moore]

I'm not getting any cmos.dat file saved when changing CMOS settings in RISC OS.

I created a cmos.dat file full of zeros, and this is loaded when the core first boots up, but if I make any changes, these aren't saved back to the file. Deleting the file loads the default settings from the core, but any changes aren't saved.

Any help would be greatly appreciated.
