The VXIpc 800 uses the PCI local bus and ISA bus for peripheral 
expansion. The PCIbus is a 32-bit multimaster bus that achieves a top 
throughput of 132 MB/s and can handle numerous peripherals. The ISA 
bus is the legacy peripheral bus found on current and older PCs.

For information on installing and configuring these peripherals for use 
with the VXIpc 800, refer to the 

c:\images\manuals

 directory. The 

drivers.txt

 file explains how to install support for each peripheral. 

This directory also contains manufacturer’s documentation for the 
video, PCMCIA, and SCSI peripherals. Also refer to the 

readme

 files 

for the most up-to-date information.

Table 1-1 lists the various peripherals and describes the external 
connector, its bus interface, and its function.
