aibb tells me MMU status - OFF

[Boot_WB]

Hello,

Wondering if anyone has had &/ resolved this problem.

HW: A1200, 3.1 roms, Blizzard 1240 (DCE ver) @33MHz , 128mb Ram (1 simm).
SW: OS3.9 fresh install.  
Wordworth7.0/multiplot/mathscript/turboprint/MUI/magicWB/idefix97 also installed.

When I run AIBB or Sysinfo the MMU status is OFF.  

I've tried installing 68040.library from aminet/biz/p5
Following the readme instructions I renamed:
68040dummy.library to 68040.library
68040.library to 68040new.library.  
As I didn't have an existing 68040.library I didn't rename it 68040old.library - as it didn't exist.
I got multiple recoverable alerts 0100 000F (task 7800ca58) on bootup which froze and crashed eventually.  I understand this is something to do with exec, but don't know any further.

Have also tried installing mmulib from aminet - same problem, repeated 0100 000f errors - can't remember if it was the same task.
(ended up knackering my partitions aswell in all the reboots, had to reinstall from scratch :¬( )

Is it a knackered MMU? A not-quite-properly working blizzard? Is it something missing form the software environment?

Any suggestions most appreciated - I've tries everything I can think of for now.

Regards

Good call!

Changed the SIMM, put the libraries back in: no more recoverable errors, and AIBB now says MMU on.
Should've thought of that myself, really, as had a similar PC (yuk!) problem a while back.

Many thanks
