Technical Specifications
Technical Summary
The Compal LA-4112 schematic, revision 1.0 dated 2008-05-14, documents a motherboard built around the Mobile AMD S1G2 CPU platform with ATI RS780/RX781 northbridge and ATI SB700 southbridge core logic. Graphics are handled by a discrete ATI M82-SCE GPU with dedicated VRAM. The system BIOS is stored on a 25LF080A SPI ROM. Embedded controller functions are managed by an ENE KB926 EC/KBC. Audio is provided by an IDT9271B7 codec, and networking by a Realtek 8102EL 10/100M LAN controller. Memory configuration supports dual-channel DDR2 SO-DIMMs across two slots. The thermal management subsystem uses an ADM1032ARMZ sensor. A JM385 5-in-1 card reader controller is integrated for SD/MMC/MS/MSPro/XS media support.
