Taiwan Commate Computer Inc.(COMMELL), the worldwide leader of Industrial ATX mainboard, introduced the  MicroATX motherboard MS-C75 that designed for the 3rd generation Intel Core i7/i5/i3 processors in the rPGA988B socket. The MicroATX mainboard based on intel QM77 Express chipset, QM77 Express chipset is part of the mobile Intel 7 Series Chipset family, along with a  intel 3rd generation 22 nm Core i7/i5/i3, the Intel processors  with HD Graphic 4000 that contains a refresh of the seventh generation graphics core, DX11 Smoother rendering at higher resolutions for an improved 3D experience, OGL4.X  Improved realism for OGL 3D . based application and lower power consumption, this innovative two-chip solution provides Intel Intel Hyper-Threading technology which giving you smart multitasking performance to move between applications quickly. This platform delivers higher performance, energy efficiency, most secure and manageable, It is ideal for a various range of applications, such as industrial control and automation, gaming, Medical Instruments, Surveillance Server, Military systems, print imaging and digital signage etc.

Onboard Intel® 82579LM GbE controller support Intel® AMT 8.0 feature on primary LAN port. The BIOS is ready to support Intel® AMT 8.0 feature. The necessary prerequisite is your CPU must support Intel® vPro technology, ex. i7-3610QE

For further instruction about the Intel® AMT features and set up, please refer to the iAMT Setting.pdf
