Option Boards

The following paragraphs describe how to install and remove ISA and PCI option boards. The system I/O board has two dedicated ISA bus master expansion slots and nine dedicated PCI bus expansion slots (see Figure 4-13).

The high-performance PCI local bus allows the adoption of newer networking technology, such as 100 Mega-bit/second Ethernet NICs, with a minimum of effort and without concern for I/O bottlenecks. The PCI local bus offers up to 133 Mega- byte/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.
