PCI Slots
There is a total of five Peripheral Component Interconnect (PCI)
32-bit, 33 MHz connectors on the system board.
The PCI slots accept 3.3 V and 5 V PCI 32-bit 33 MHz cards, and
Universal PCI cards (which are 3.3 V or 5 V compatible). Refer to
the table on the following page for the different PCI board
installations.
If an AGP Pro graphics card is present in the AGP Pro graphics slot
(Minitower models only), the PCI slot nearest the AGP slot
cannot be used.
The maximum supported power consumption per slot is 25W, either from
the 5V or the 3.3V supply and must respect the electrical specifications of
the PCI 2.2 specification. Total power consumption for the PCI slots must
not exceed 60 W.
The power consumption of each PCI board is automatically reported to the
system through the two Presence Detect pins of each PCI slot. These pins
code the following cases:
No accessory board in the PCI slot.
7 W maximum PCI board in the PCI slot.
15 W maximum PCI board in the PCI slot.
25 W maximum PCI board in the PCI slot.
The following table shows the various PCI board installations for the
different PCI slots:
