Yeah. SwapMMUMode: Trap=$A05D
You can check the current mode by looking in Low Mem. Location is:
MMU32bit EQU $0CB2
Possible values:
false32b EQU 0
true32b EQU 1
FYI, I have confirmed a value of 1 on a 32 bit system, though I don't
have a 24-bit system to test on except my PB145 and I don't have FB
installed on it's micro hard-drive (40 Mb).
It shouldn't be hard to check that and make the call if necesary. I
suspect that's most of what MODE32 does. It's part of the OU OS
Utilities (manager). It seems call-able in C with SwapMMUMode(); or in
Assembly with _SwapMMUMode. Hope this means something to someone.
Later,
