A revised version of the Tech Note (#176) will be out in February to include
the new SE motherboard as well as the IIx and SE/30 memory configurations.
Until that time, here are the jumper settings for memory on the newer SE
motherboards with the jumpers...

512K       Jumper on 2/4MB
1 MB       Jumper on 1MB 
2 MB       Jumper on 2/4MB
2.5 MB     Jumper off
4 MB       Jumper off
 
We would have had this info out sooner, but we just found out ourselves a
very short time ago.
