Technical Specifications
Technical Summary
The Quanta BF4 motherboard is designed for the Mobile P4 prescott CPU platform using a Micro-FCPGA socket. The platform is built around the Montara-GT North Bridge and ICH4-M South Bridge, supporting DDR SDRAM 2.5V across two DDR-SODIMM slots. Graphics are handled by an NV34M GPU controller with AGP 4X at 266MHz and 1.5V, complemented by 64MB of dedicated video RAM. The system integrates a PC87551 KBC with EC functionality, a PC87391 Super I/O, and an AC97 audio codec paired with a TPA0312 audio amplifier. Networking is provided by a BCM5901KFB LAN controller and a BCM5705KFB Ethernet controller. The clocking solution uses an ICS950810BGT and ICS91718AM clock generator. A PCI1520 CardBus controller and Mini-PCI socket provide expansion capabilities.
