The jumpers are pretty well labeled and described on the board.   You can jump the speed of the RAM (60ns or 70ns I believe)   And the other jumper lets you cache the ROM data to RAM for theoretically better performance but you loose 512kb.   That's about it...

To disable on start-up hold down the "2" key.  To re-enable hold down the Ctrl-A-A (reboot) keys for more then 10 seconds.  (It's also re-enabled after powering off the system)
