The ProSavageDDR P4N266 (VT8703 “Twister P4” North Bridge plus VT8233 South Bridge) is a high
performance, cost-effective and energy efficient SMA chip set for the implementation of mobile personal computer
systems with 400 MHz (100 MHz QDR) CPU host bus (“Front Side Bus”) based on 64-bit Intel Pentium-4 super-
scalar processors. This data sheet describes the VT8703 North Bridge portion of the P4N266 chipset (except for
detailed register descriptions for the integrated graphics controller which are described in a separate document
published by S3 Graphics). The VT8235 South Bridge is described in a separate data sheet.
