VIA NAB-7400 Overview
The VIA NAB-7400 Mainboard is an ultra compact native x86 platform optimized for today's
demanding network and productivity applications. The mainboard is based on the VIA C7
NanoBGA2 processor featuring an embedded hardware MPEG-2 video decoding accelerator.
Its integrated VIA UniChrome™ Pro AGP graphics provide rich digital media performance.
With the sizable memory bandwidth of DDR2 400/533MHz DIMM and the high data transfer
speeds of ATA-133, the VIA NAB-7400 delivers the increased performance levels required
by today’s digital media applications.
The latest in high-bandwidth connectivity features two USB 2.0 ports (and the ability to
support up to 6 more USB ports using the available onboard pin headers. One of the USB
ports is reserved for wireless LAN), one COM port (and three COM pin headers), and four
10/100 or Gigabit Ethernet ports for extended broadband connectivity. The VIA NAB-7400
also have two mini PCI interface and one 32-bit PCI Golden Finger for expandability options.
The VIA NAB-7400 is compatible with a full range of Mini-ITX chassis as well as FlexATX and
MicroATX enclosures and power supplies.
The VIA NAB-7400 is fully compatible with Microsoft® and Linux operating systems and is
available in a variety of configurations.
