Peripheral Component Interconnect (Pci) Backplane - Compaq AlphaServer DS20E Reference Manual

Peripheral Component Interconnect (PCI)
Backplane
The system board has two P-Chips which create two 3-slot 64-bit PCI buses
running at 33 MHz. There are 6 PCI slots with slot-6 being shared for an ISA
slot. When slot-6 is in use by ISA, the sixth PCI slot cannot be used.
The system uses a Cypress South Bridge (CY82C698), which is a highly
integrated peripheral solution for PCI-based motherboards. It provides a
bridge between the PCI bus, ISA bus, and the IDE peripherals. Support for six
PCI slots is provided when one of the slots is used for the optional 2-way
combination module (Enet and Video). Information for installing PCI options
is provided in Chapter 8.
