DKB 1240 jumpers and MMU question

[Kitch]

I've been playing around on my A1200 with various cards and CPU's. I've been using Sysinfo V3.23 to test the speeds and I have question regarding my DKB 1240.
Sysinfo keeps telling me that the MMU is not in use even though it lists the CPU as a 68030. The card's previous owner had swaped in an 68EC30 for the original 68030 but I've just refitted the original MC68030RC50B. Any idea's what going on?
Do I need to change a jumper over some where? What are jumpers "J1"and "J3" for? "J3" has what looks like an "Alt" or "CPU" position but I don't no what that does.
Thanks, Andrew

Thanks for the link to SysSpeed but I havn't been able to successfully unpacked it onto a floppy.
So I'm still playing around with SysInfo V3.23. I've seen a screen shot in a magazine with the same version of SysInfo listing the MMU as "enabled", as opposed to my MMU being "not in use".
Any idea what I have to do so that SysInfo sees my MMU as "enabled"?
Thanks Andrew

Thanks for the advice. The A1200 I'm using at the momment doesn't have a hard drive. I'm also quite new to all this and struggling a bit, although JaXanim is trying his best to help me. Until I get SysSpeed up and running SysInfo can fall under the heading of "better than nothing".
