2.6.3 PCI slots
There are five 32-bit PCI slots on this motherboard, including an ASUS
proprietary BlueMagic PCI slot. The slots support PCI cards such as a
LAN card, SCSI card, USB card, and other cards that comply with PCI
specifications. The following figure shows a LAN card installed on a PCI
slot.
2.6.4 AGP Pro slot
This motherboard has an Accelerated Graphics Port (AGP) Pro slot that
supports +1.5V AGP cards. When you buy an AGP card, make sure that
you ask for one with +1.5V specification. Note the notches on the card
golden fingers to ensure that they fit the AGP slot on your motherboard.
If you installed an incorrect AGP card, such as a SiS305-based AGP card
or any other 3.3V AGP card, the onboard red LED (AGP_WARN) lights up,
an indication that the card is not supported on the motherboard. As long as
this LED is lighted, you cannot turn on the system power even if you press
the power button, thus preventing permanent damage to the motherboard.
Install only 1.5V AGP cards on this motherboard!
