3.16.2 What to Do

1. Locate the jumpers on the main logic board.

   A main logic board jumper is identified by its jumper address, labeled on the board with the letter "J" followed by four numbers (JXXXX). Jumper pins are located immediately adjacent to the jumper address. On the board, pin 1 is marked with an asterisk.

   For information about jumper locations, see "3.15 How to Set the Serial Port Jumpers".

2. Set the main logic board jumpers J2703 and J2804.

   Using long-nose pliers, place a shunt over the appropriate pins according to the following table.

   Flash PROM jumper	A shunt on pins 1 and 2 selects	A shunt on pins 2 and 3 selects	The default shunt is on pins	Signal that is controlled
   J2703	Write-protect	Write-enable	1 and 2	FLASH PROM PROG ENABLE
   J2804	High-half booting	Normal (low-half) booting	2 and 3	XOR LOGIC SET
