Intel 855GME Chipset
The CPCI-7806/CPCI-7806RC incorporate the latest Intel chipset technology, the
855GME. This chipset utilizes Advanced Hub Architecture (AHA). The AHA
allows for increased system performance by separating many high-bandwidth
I/O accesses from PCI accesses, relieving bottlenecks on the PCI bus. Furthermore,
the 855GME chipset brings new levels of integration to motherboard chipsets and
provides additional features such as Ultra ATA/100, Integrated LVDS and Serial
ATA.
