Technical Summary

The Quanta G-Note Montevina motherboard, document number 2A revision C1 dated April 14, 2009, is built around the Intel Penryn 478P (uPGA)/35W CPU platform paired with the Cantiga GMCH northbridge and ICH-9M southbridge. System management is handled by an ITE IT8502E/JX EC/KBC, while the BIOS resides on a SPI EEPROM. Memory configuration consists of two DDRIII SODIMM slots supporting DDRIII 800/1066 MT/s. The charging subsystem is managed by an ISL88731A charger, with power regulation provided by ISL6266A, RT8204, TPS51116, and ISL6237. Integrated audio is driven by an ALC269Q codec, and networking is handled by a REALTEK RTL8111DL LAN controller. The board also features a JMB385 card reader controller, a SLG8SP568/ICS9LPRS393 clock generator in QFN68 package, and a LIS244ALTR G-sensor.
