Installing Fast Peripherals On The Pci Bus - HP Vectra XW Optimization Manual

The PCI Bus

Installing Fast Peripherals on the PCI Bus

The HP Vectra XW provides six slots for accessory boards. Two of these
slots are already occupied by your advanced graphics controller and
LAN controller. The remaining four slots are available for installing
accessory boards and can be used to add extra peripheral devices to
your Personal Workstation. These slots are of two different types.
The HP Vectra XW uses the Peripheral Component Interconnect (PCI)
bus as the main channel for connecting peripheral devices. Your system
also provides an Industry Standard Architecture (ISA) bus for
backwards compatibility with any ISA accessory boards you may need
to use.
The difference in performance between the PCI bus and the ISA bus is
significant; the PCI bus can transfer data more than 16 times faster
than the ISA bus.
The ISA bus is 16-bits wide
and can transfer data at up to
8 MB per second
