Technical Specifications
Technical Summary
The Compal JALA0 (LA-4221) motherboard, revision 1.0, is built around the Intel Penryn processor platform with the Cantiga chipset and ICH9-M southbridge. It supports dual-channel DDRII memory via two 200-pin SO-DIMM slots. Graphics options include Ati M82M, nVidia 9MGS, or nVidia 9PGE2 discrete GPUs. The system utilizes an ENE KB926ME EC/KBC and an ALC268 audio codec. Both the system BIOS and EC firmware are stored on separate 2MB SPI flash ROMs. The charging solution is handled by a GL667 IC, and wired networking is provided by a Broadcom BCM5764M GbE controller. A JMB385 card reader and SMSC EMC1402-1 thermal sensor are also integrated.
