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

Don't trust SysInfo for any system information or benchmarks. The application is way too old to give any reliable results on modern systems.

I'd recommend SysSpeed. Granted, it's not that fresh either, but at least it gives more reliable results for faster 030, 040 and 060 systems.

68030 MMU is not in use by default. You need to run some application using the MMU before it is reported as being in use.

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

Sysinfo has been called "Mysinfo" for years! It is not reliable! specially for cpu information.
Why are you trying to use a floppy to unpack SysSpeed? Use your hard drive.
As to your last question, you really can't do anything to Mysinfo to get real world answers from it. It just cannot be trusted.

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".
