Upgrading Your System 4-19
Option Boards
This section describes how to install and remove ISA and PCI option boards.
The system board has two ISA bus expansion slots and four PCI bus expansion
slots. One of the ISA connectors shares a chassis expansion slot with a PCI
connector.
The high-performance PCI local bus allows the adoption of newer networking
technology, such as 100 MB/second Ethernet NICs, with a minimum of effort
and without concern for I/O bottlenecks. The PCI local bus offers up to 133
MB/second bandwidth.

Installation Considerations
Newer adapters, designed for Plug-and-Play systems, are automatically
configured by the system without any user intervention. Older ISA adapters
must be manually configured as detailed below. Once the manual configuration
is complete, the Plug-and-Play adapters are configured around the manually
configured adapters without causing any resource conflicts.
ISA adapters can be Plug-and-Play. ISA adapters that are not Plug-and-Play
must be manually configured following the instructions supplied with the board.
The configuration is defined to the system by creating the ISA configuration file
when running the SSU. If you are adding a non-Plug and Play ISA option board,
run the SSU before installing the board. For details on running the SSU, refer to
Appendix B.
