Expansion Boards
Your system supports 32-bit PCI Plug and Play expansion boards. With
Plug and Play expansion boards, you can install a board without changing
the hardware settings. There are no system resource conflicts to resolve.
Plug and Play automatically configures the board for the system.
The PCI connectors support bus mastering and accept PCI expansion
boards that run at half the system board’s bus speed. The PCI bus handles
32 bits of data at a time, boosting system performance.
The following sections include procedures for installing and removing
expansion boards.
