Installing Fast Peripherals On The Pci Bus - HP Vectra XU 6/XXX Optimization Manual

The PCI Bus

Installing Fast Peripherals on the PCI Bus

The HP Vectra XU PC 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 PC. These slots are of two different types.
Your PC uses the Peripheral Component Interconnect (PCI) bus as the
main channel for connecting peripheral devices. Your PC 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
