Technical Specifications
Technical Summary
This Compal JALA0 motherboard, documented under board number LA-4221P revision 1.0, is built around the Intel Penryn processor platform with the Intel Cantiga chipset and ICH9-M southbridge. The system memory architecture uses two 200-pin DDRII SO-DIMM slots. Graphics options include discrete Ati M82M with 256MB GDDR2, nVidia 9MGS with 256MB GDDR2, or nVidia 9PGE2 with 256MB GDDR3. The embedded controller is an ENE KB926ME, and the system and EC firmware are stored on separate 2MB SPI flash ROMs. Audio is handled by an ALC268 codec, wired networking by a Broadcom BCM5764M Gigabit Ethernet controller, and thermal monitoring by an SMSC EMC1402-1 sensor. The charging IC is a GL667, and the card reader controller is a JMB385.
