Optimizing PCI and EISA Devices
Compaq has conducted extensive testing to determine optimal
configurations for achieving high performance and ease of use at the initial
installation of a ProLiant 5000 system. These test include integrating the
ProLiant 5000 with network operating system software, such as Windows
NT Server, and installing additional peripherals when the need arises.
This section contains Compaq recommendations for configuring the
ProLiant 5000 server to achieve optimal Windows NT Server performance.
The dual-peer PCI buses capabilities of the ProLiant 5000 server provide
high-bandwidth I/O with two buses operating simultaneously. Dual-peer PCI
buses provide an aggregate bandwidth of 267 MB/s. The I/O board has two
Pentium Pro-to-PCI bridge controllers. The controllers connect the primary
and secondary PCI buses to the host bus. The primary and secondary buses
each have assigned functions.
The configuration recommendations presented in this document focus on:
■ Primary and secondary PCI bus configurations
■ Bridged controllers and the implications of adding additional bridged
controllers
Primary PCI Bus
■ Supports dedicated PCI slots 5-8.
■ Supports the EISA bridged bus.
❏ Supports up to three EISA slots (one dedicated, two shared
EISA/PCI).
❏ Supports integrated EISA peripherals (video, timers,
keyboard, mouse).
Secondary PCI Bus
■ Supports PCI on shared slots 2 and 3 and dedicated slot 4.
■ Supports the Integrated 32-Bit Fast-Wide SCSI-2 controller.

What is a Bridge?
A PCI bridge connects two independent PCI computer buses together and
allows the buses to communicate with each other. By creating hierarchical
PCI buses, the PCI bridge overcomes the electrical loading limits of the PCI
bus.
PCI Bus Numbering
PCI buses are assigned PCI bus numbers beginning with Bus # 0 for the
primary PCI bus (Slots 5-8) and Bus # 1 for the secondary PCI bus (Slots 2-
4).
PCI bus numbering changes depending on how many PCI bridged
controllers are installed (ex: SMART-2/P Controller) and whether they are
installed in the primary or secondary PCI bus, and slot order of each bus.
For example, in the default factory configuration (Table 1), the SMART-2/P
controller is installed in the primary PCI bus (Slot 5), the SMART-2/P is a
PCI bridged controller causing the bus numbering to change. As stated
previously, the default bus numbers for the ProLiant 5000 without any
bridged PCI controllers installed is Bus # 0 for the primary PCI bus and Bus
# 1 for the secondary PCI bus; adding the SMART-2/P controller to the
primary PCI Bus causes the bus numbers to change to Bus # 0 for the
primary PCI bus, Bus # 1 for the SMART-2/P bridged PCI bus, and Bus # 2
for the secondary PCI bus.
Compaq tested the installation and configuration of bridged PCI controllers
and recommends that the configuration tables (Tables 1-6) be utilized to
minimize the possibility of changing the bus numbers and causing device
drivers such as the NETFLX3.SYS to fail when loading. The failure is due to
the initial bus number used while configuring the PCI NetFlex-3 controller
and adding a bridged controller that changes the bus number of the PCI bus
that the NetFlex-3 controller is installed in. Windows NT does not update
the network interface card configuration which causes any network interface
card to fail during device driver initialization.
Any time additional bridged PCI controllers are added or removed from the
primary bus of an existing configuration, the secondary PCI bus number
changes requiring the network interface controllers to be reconfigured

Following the recommended configuration tables minimizes the possibility
of this occurring and having to reconfigure the NetFlex-3 controller and also
gives the best performance configuration by dividing the bus load.
Factory Configuration
Table 1 describes the factory configuration with one Netelligent 10/100 TX
PCI UTP network interface controller (NIC) installed in the secondary PCI
bus (Slots 2-4) and one SMART-2 SCSI Controller installed in the primary
PCI bus (Slots 5-8).

In Table 6, by adding the SMART-2/P controller to the primary PCI bus
(Slot 7), the PCI bus number of the secondary PCI bus changes causing the
NETFLX3.SYS device driver to fail while attempting to load.
The following steps highlight the process to correct the issue:
■ Double-click the Network icon from the Control Panel, record
pertinent information on the network adapters (IP address, etc.)
■ Close the Network Settings dialog box.
■ Double-click the Compaq Net icon to launch the Compaq Advanced
Network Control Utility from the Control Panel.
❏ Highlight the failing adapter and select the Uninstall option.
❏ Highlight the adapter again and select the Install option.
■ Close the Compaq Advanced Network Control Utility dialog box.
■ Enter the information (IP address, etc.) recorded earlier on the
network interface card being reinstalled in the Network Settings
dialog box..
■ Shutdown and reboot the server.
NOTE: Any time additional bridged PCI controllers are added or removed from the
primary bus of an existing configuration, the secondary PCI bus number changes,
requiring the network interface controllers to be reconfigured.

Hardware Abstraction Layer Multiprocessor
Support
This section provides an overview of the Hardware Abstraction Layer
support for the Compaq ProLiant 5000. The Compaq ProLiant 5000 is a
Multiprocessor Specification-based server and takes advantage of additional
capabilities provided by Intel MPS capable processors. The HAL is a layer
of software that interacts directly with the computers hardware and is one of
the modular components that make up the Windows NT operating system.
The Microsoft Multiprocessor HAL (HALMPS.DLL) included with
Windows NT will function on the Compaq ProLiant 5000 server and
provides basic HAL functionality
