Technical Specifications
Technical Summary
This Wistron JM41_Discrete-1 motherboard, project code 91.4CQ01.001 with PCB P/N 48.4CQ01.0SB revision 08274-1 dated April 7, 2009, is built around an Intel Cantiga-GS SFF CPU platform paired with an ICH9M SFF southbridge. Graphics are handled by an ATI M92-S2 GPU with switchable graphic capability and 512MB of DDR3 VRAM. The embedded controller is a Winbond WPC E773LA0DG, while the audio subsystem uses a Realtek ALC269Q codec. Networking is provided by an Atheros AR8131 LAN/WLAN IC. The board features a 2MB BIOS flash, DDR3 memory running at 800/1066 MHz, and a comprehensive power delivery system including TPS51125, RT8202, ISL6263A, ADP3207A, and RT9026 regulators. Charging is managed by a MAX8731A IC, and thermal monitoring is handled by an EMC2103 sensor.
