Function

Label

Autoconfigure mode jumper

E2

Note:The function of E2 is to signal to the configuration program that the configuration of the board has changed. To trigger this function, before powering on the computer change the setting of jumper E2 from pins 1 & 2 closed to pins 2 & 3 closed, or vice-versa. Then the configuration program will auto-detect the amount of memory currently installed.
