Pci Slots - HP Vectra VL800 Technical Reference Manual

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.
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:

1.
A 64-bit card can be installed in a 32-bit slot. However, this card will only operate in 32-bit
mode.
2.
A 66 Mhz card can be installed in a 33 MHz slot. However, this card will only operate in
33 MHz mode.
The system board and BIOS support the PCI specification 2.2. This
specification supports PCI-to-PCI bridges and multi-function PCI devices,
and each of the five PCI slots have Master capabilities.
The PCI slots are connected to the ICH2 PCI 32-bit 33 MHz bus.
