Plug And Play; Nlx Design; Isa Bus; Pci Local Bus - NEC POWERMATE 5100 Service Manual

Plug and Play

The system comes with a Plug and Play BIOS in support of Plug and Play
technology. Plug and Play simplifies setup procedures for installing Plug and
Play expansion boards. With Plug and Play, adding a Plug and Play expansion
board is done by turning off the system, installing the board, and turning on the
system. There are no jumpers to set and no system resource conflicts to resolve.
Plug and Play automatically configures the board. (Some Plug and Play devices
may need to be jumpered if used in a system running the Windows NT
operating system.)

NLX Design

The system is designed to conform to the NLX standard. Electrical and
mechanical interfaces and board dimensions are standardized.
T
Signal and power connections to the system board are carried through the
riser board.
T
The system board is free of internal cabling.
T
A chassis latch releases and secures the system board for easy removal
and replacement.

ISA Bus

The system board uses the ISA bus for transferring data between the processor
and some I/O peripherals and expansion boards. The ISA bus supports 16-bit
data transfers and typically operates at 8 MHz.

PCI Local Bus

The 32-bit PCI local bus is the primary I/O bus for the system. The PCI bus is a
highly integrated I/O interface that offers the highest performance local bus
available for the Pentium processor. The bus supports burst modes that send
large amounts of data across the bus, allowing fast displays of high-resolution
images.
The PCI local bus is a high-performance bus that provides a processor-
independent data path between the CPU and high-speed peripherals. The PCI
bus is a robust interconnect mechanism designed specifically to accommodate
multiple high performance peripherals for graphics, full motion video, and
LAN.
The PCI local bus supports memory transfer rates of over 100 MB per second
for reads and over 120 MB per second for writes, depending on processor
configuration.
