2.6.3 PCI slots
There are six 32-bit PCI slots in this motherboard. 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 slot
This motherboard has an Accelerated Graphics Port (AGP) 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 (WARNING) 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!
