Technical Specifications
Technical Summary
This Wistron Corporation motherboard, project code 91.40U01.001, dated 2003/10/01, 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 CSP32 GPU. The system uses DDR memory across two slots. The embedded controller is an M38857 KBC, and the audio codec is a CS4299XQ. Power management is handled by a combination of MAX1645 charging IC and multiple DC/DC converters including MAX1907, MAX1715, SC2595STR, SC1486, and MAX1999. Networking is provided by a BCM4401/BCM5705M LAN IC and an 802.11a/b MiniPCI wireless slot. The firmware hub is a 4MB FWH device. Additional I/O includes a RICOH R5C593 CardBus/1394 controller and a PC87392NS Super I/O, with clock generation by an ICS 950810.
