Technical Specifications
Technical Summary
This Wistron Corporation motherboard, document number A3166 dated June 1, 2005, is built around the Intel Banias/Dothan mobile CPU platform with an Intel ICH4-M southbridge. Graphics are handled by the integrated Intel Motara-GM Plus GPU. The system BIOS is stored on an SST-49LF008F LPC flash IC. Embedded controller functions are managed by an H8S/2161B KBC. Audio is provided by an AD1981B AC97 codec. The charging architecture uses a MAX1870C battery charger/selector, supported by a suite of power ICs including MAX1977, MAX1992, MAX1907, MAX1845, MAX8873, and ALP2996M. Memory configuration consists of two on-board DDR SODIMM sockets. Networking capabilities include Intel 82562EZ 10/100 Ethernet and an Intel 82541EX Gigabit LAN controller, alongside a Mini-PCI slot for 802.11a/b/g wireless. A RICOH R5C5811 controller handles Cardbus and SD card interfaces, while an SMSC USB20H04 hub provides additional USB connectivity. Thermal management is monitored by LM83, LM26+, and DS75 sensors.
