We are currently using 486/SX 25 Megahertz processors on these mother boards.  The 25 mghz needs to be set by jumpering jp10 and jp11 and jp18. Two of these jumpers are located almost straight under where the end of the floppy will be.  Jp18 is located in a row of jumpers near the middle of the board, towards the power supply from the center.  The rest of the jumpers by Jp18 are used to set up cpu type. To select a 486/25 all the jumpers are off, Jp16 set to pins 1 and 2 jumpered.

To jumper board for 486/SX-25, jp10,11,18 on, jp16 to 1-2, all others in vicinity open.
