Technical Specifications
Technical Summary
This Wistron Corporation motherboard, project code 91.40U01.001, dated 2003/10/05, is built around the Dothan/Banias Mobile CPU platform with an MCH-Odem 855PM northbridge and ICH4-M southbridge. Graphics are handled by an ATI M9 CSP GPU. The system uses DDR memory and features an M38857 EC/KBC, a CS4299XQ audio codec, and a PC87392NS Super I/O. Power management is handled by multiple ICs including the MAX1645 charger, MAX1907, MAX1715, SC2595STR, and MAX1999. Networking is provided by a BCM4401/BCM5705M LAN IC, while a RICOH R5C593 manages CardBus and 1394 connectivity. The firmware is stored on a 4MB FWH. The document number is A3247.
