The NLX EX3 mainboard is a high-performance personal computer
mainboard based on the Pentium
®
II processor. The mainboard supports
Intel
®
82558 Network chip, YAMAHA
YMF715 sound chip and ATI 3D
RAGE PRO/RAGE IIC for graphics accelerator. The Pentium
®
II processor
supports MMX
TM
(Multimedia Extension) technology.
The mainboard uses the highly integrated Intel
®
82440EX AGPset which
optimize the system bandwidth and concurrency with the implementation of
Quad Port Acceleration (QPA). QPA provides 4-port concurrent arbitration
of the processor bus, graphics, PCI bus and SDRAM.
The Intel
®
82371EB chipset integrates all system control functions such as
ACPI (Advanced Configuration and Power Interface). The ACPI provides
more Energy Saving Features for the OSPM(OS Direct Power Management)
function. The Intel
®
82371EB chipset also improves the IDE transfer rate by
supporting Ultra DMA/33 IDE that transfers data at the rate of 33MB/s.
The mainboard also supports the W83781D System Hardware Monitor
Controller as optional function. The System Hardware Monitor function
includes: CPU /power supply/chassis fan revolution detect, CPU/system
voltage monitor, system temperature monitor, and chassis intrusion detect.
