An asterisk (*) indicates the default value of each jumper. NOTE: For two-position jumpers (3-post), "RIGHT" is toward the bracket end of the board; "LEFT" is toward the memory sockets. JU80 CRT TYPE SELECT TOP = Color * BOTTOM = Monochrome JU81 PASSWORD CLEAR INSTALL = Reset to null REMOVE = Normal operation * JU82 WATCHDOG TIMER LEFT = Normal reset * RIGHT = Enable watchdog JU83 CMOS CLEAR INSTALL = Clear CMOS REMOVE = Operate * JU84 P5A SPEAKER CONNECT INSTALL= Connect speaker data signal to pin 8 of Combo I/O connector (P5A) * REMOVE= Disconnect JU85 P5A RESET CONNECT INSTALL= Connect reset data signal to pin 1 of Combo I/O connector (P5A) * REMOVE= Disconnect JU86 INTERRUPT 12 (IRQ12) SELECT INSTALL = Dedicate IRQ12 to PS/2 mouse. * Trenton Support Center – T2V Technical Information -- Jumpers, Connectors and Memory 1 TRENTON Technology Inc. 2350 Centennial Drive • Gainesville, Georgia 30504 Sales (800) 875-6031 • Phone (770) 287-3100 • Fax (770) 287-3150 REMOVE = Make IRQ12 available for system use. JU88 P4B PS/2 MOUSE/KEYBOARD INTERFACE DATA SELECT LEFT = Keyboard data RIGHT = Mouse data * JU88A P4B PS/2 MOUSE/KEYBOARD INTERFACE CLOCK SELECT LEFT = Mouse clock * RIGHT = Keyboard clock NOTE: JU88 and JU88A must be set to the same function (either mouse or keyboard) for the peripheral to function properly. JU89 3.3V MONITOR ENABLE INSTALL = Enable 3.3V monitor. REMOVE = Disable 3.3V monitor. * NOTE: JU89 enables the 3.3 volt monitor, which monitors the 3.3V power plane of the backplane. This voltage is routed to the SBC via the PICMG® connector. The monitor generates a RESET to the SBC if 3.3V is below tolerance. If your system does not supply 3.3V to the backplane, this jumper must be removed (disabled).

Normally only the Main Block is updated when a new BIOS is flashed into the system.

The jumper settings depend on the bare board revision level as indicated in the following charts.
