System Board 4-13
The Flash ROM allows the system and video BIOS to be upgraded with the
BIOS Update utility, without having to physically remove the ROM (see
Section 2 for further information on the BIOS Update utility). The Flash ROM
supports the reprogramming of the system BIOS and the video BIOS.
System Memory
The system comes with between 32 MB and 256 MB of SDRAM installed in
DIMM sockets on the system board.
The memory configuration consists of two sockets. The DIMM sockets accept
168-pin, 64-bit (non-ECC) 16-, 32-, 64-, and 128-MB DIMMs. See “DIMM
Sockets” for a list of supported DIMMs.
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.)
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 Celeron or 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 and full motion video.
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.
