2-4 Install AGP4X with LED1 & JP4 Safeguard
1. To install AGP 4X add-on card, please insert the card into the AGP
slot on board, and connect your monitor directly to the AGP 4X card.
To protect the system from burning out by an incorrect AGP card,
please set JP4 1-2 closed, so it will allow only 1.5V AGP 4X card to
boot system. If users cannot boot up the system with an AGP card
inserted in the slot, then the card is not a correct one. Simply
changing the AGP card to a 1.5V AGP 4X card will solve the problem.
2. LED1 is a Warning LED. Whenever an AGP card is not inserted to
the AGP slot, or if the card is not a correct one, LED1 will keep
lighting up until a proper installation is done.
Warning: if 3.3V AGP 2X card is mistakenly inserted for
booting the system, the high voltage will burn out the 1.5V
circuitry on board. Never use a 3.3V or an unknow AGP in
this case.
