Technical Specifications
Technical Summary
The Quanta EA41_BM (14") motherboard, project code ZQMB421 revision A1A dated June 13, 2014, is built on the Intel Bay Trail-M platform. Graphics processing is handled by an N15V-GM (GeForce 820M) GPU. System management is controlled by an NPCE985LB1 embedded controller in an LQFP128 package. Audio is provided by an ALC283 codec. The main BIOS is a 1.8V BIOS + TXE SPI ROM with 64Mb capacity, while the EC firmware resides on a separate 3.3V EC code SPI ROM of 1Mb. Memory support includes DDR3L via a single SO-DIMM slot with a maximum capacity of 8GB. Peripheral connectivity includes a GL834L card reader IC and an RTL 8111 GS-CG LAN controller. Wireless connectivity is supported via a WLAN / BT Combo Half Mini Card.
