PCI Local Bus
Your computer's PCI architecture represents the latest in local bus technology. It delivers
maximum computer performance by providing a wider data path, greater speed, and improved
expandability. Simply put, PCI removes various types of peripheral controllers from the slower
ISA bus and connects them directly to a faster 32-bit data path. This results in a faster 32-bit
I/O bus for devices such as SCSI controllers and high-end video adapters.
Some of the PCI local bus features are:
•
Highest performing bus on the market today
•
Offers the best expandability for high-performance peripheral devices
•
Supports multiple bus masters
•
32-bit data transfer at 132 MB per second (maximum)
•
PCI-to-ISA bridge circuitry allows continued use of existing ISA expansion
boards on the market that do not support the high data transfer rate of PCI
