Expansion Boards; Locating Expansion Slots - NEC PowerMate Professional 9000E Series User Manual

Expansion Boards

Your system supports industry standard architecture (ISA)
8- and 16-bit expansion boards (Plug and Play and
non-Plug and Play). It also supports 32-bit Peripheral
Component Interconnect (PCI) expansion boards, which are
Plug and Play.
With Plug and Play expansion boards, you can install a board
in an expansion slot without changing the hardware settings.
There are no system resource conflicts to resolve. Plug and
Play automatically configures the board for the system.

Locating Expansion Slots

The system has five expansion slots (see the following
figures):
T
one ISA slot
T
three PCI slots
T
one shared PCI/ISA slot.
ISA expansion slots support industry-standard 8-bit or
16-bit expansion boards. The PCI/ISA slot also supports PCI
expansion boards.
The three PCI slots 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, being
wider as well as faster than the standard ISA bus. PCI boards
can send and receive data much faster, boosting system
performance.
