Technical Specifications
Technical Summary
This Compal KIWB1/B2_LA4601P motherboard, revision 0.1 dated 2008/03/25, is built around the Mobile Penryn uFCPGA-478 CPU platform with Intel Cantiga_GM/PM core logic paired with the ICH9-M southbridge. Graphics processing is handled by an NVidia NB9P/NB9M GPU with dedicated 32*32 VRAM. The system BIOS is stored across four banks (0, 1, 2, 3) and is controlled via SPI interface between the ICH9-M and ENE KB926 EC/KBC. Memory configuration supports dual-channel DDR3 via two SO-DIMM slots. The integrated audio codec is a Realtek ALC272, and networking is provided by a BCM5906/BCM5784M LAN controller. A Realtek 5158E card reader, ICS9LPRS387AKLF clock generator, and PS8101T HDMI controller complete the core component set.
