Compaq ProLiant 1000 PCI Bus Numbering in a Microsoft Windows NT Environment - Page 6

PCI Bus Numbering in a Microsoft Windows NT Environment 6 PCI Architecture and Bridged Controllers There are four primary bus expansion schemes for PCI systems, namely the PCI-to-PCI bridge architecture, Dual-Peer PCI Bus architecture (see Figure 1), Highly-Parallel Bus architecture (see Figure 2), and Triple-Peer PCI Bus architecture (see Figure 3). The Compaq servers discussed in this white paper and used in the Integration Lab testing include these PCI architecture system designs. Refer to the "Compaq Server and Option Hardware" section of this white paper for more information. 133MHz FSB Pentium III 133MHz FSB Pentium III 133MHz 1.06GB/s 133MHz SDRAM DIMMs 133MHz 1.06GB/s RCC 3.0 PCI/Memory Controller 267 MB/s OSB4 133 MB/s 2 x 64-Bit PCI Slots SuperIO Controller ISA Slot 4 x 32-Bit PCI Slots Server Feature Card in 32-bit PCI slot Figure 1.
