Technical Specifications
Technical Summary
The Wistron MB2M motherboard, project code 91.4U401.001, is built around the Intel Yonah/Merom CPU platform with a Calistoga GM graphics architecture and an ICH7-M southbridge. The system memory architecture is DDRII 533/667, distributed across two slots (Slot 0 and Slot 1). The embedded controller is an ENE KB3910SF, and the audio subsystem is handled by a Realtek ALC883 codec. The board utilizes a 1MB Flash ROM for BIOS storage. Power management is managed by a MAX8725 charging IC, alongside MAX8743, TPS51120, and MAX8736A power ICs. Networking is provided by a Realtek RTL8101E 10/100 LAN controller and an 802.11 b/g wireless module. The integrated card reader is a Ricoh R5C832.
