2-4 Install VGA / AGP4X with LED2 & Jp11 Safeguard
1. To install on-board VGA, please connect your monitor directly to VGA
connector on board. Default Jp11 (2-3 closed) is designed to assure
booting system with 1.5V on-board VGA or 1.5V AGP4X add-on card.
User can choose either VGA or AGP4X as the initial display by
changing BIOS Setup (see "PNP/PCI Configurations" in BIOS Setup).
However, if 3.3V AGP 2X card is mistakenly inserted for booting the
system, the high voltage will burn the 1.5V circuitry on board. Never
use a 3.3V or an unknow AGP card on this mainboard.
2. A safe installation of AGP4X add-on card is set Jp11 to 1-2 closed,
resulting in allowing only 1.5V AGP 4X card to boot system. With
Jp11 1-2 closed, system even cannot boot with on-board VGA. In
this case, if user cannot boot with an AGP card inserted in AGP slot,
it indicates that the AGP card is not a 1.5V AGP card. The AGP card
should be changed until a 1.5V AGP4X card is inserted.
3. LED2 is a Warning LED. Whenever Jp11 is set at 1-2 closed for an
AGP4X card installation, and if the AGP slot is yet left empty, or if
the AGP card is not a correct one, LED1 will light up until a proper
installation is done.
