AIGCVIA KT266是一款由 VIA Technologies, Inc.（威盛科技股份有限公司）設計并生產的專用集成電路（Application-Specific Integrated Circuit, ASIC）芯片組，專為臺式機主板應用設計，特別是在ATX架構的個人計算機中。它在1990年代中期作為英特爾 Pentium Pro處理器的主流搭配出現，支持高速前端總線以及多通道內存控制器等功能。
產品手冊通常會詳細介紹KT266的各項特性，包括但不限于：
- 芯片組架構和規(guī)格：描繪KT266如何與Pentium Pro處理器協同工作，提供對Socket 8針腳接口的支持，以及其前端總線速度（如60MHz或75MHz等）、內存類型（如SDRAM、EDO DRAM）和容量的最大支持。
- BIOS和BIOS更新：包含關于如何通過BIOS設置來配置系統(tǒng)時鐘頻率、內存刷新率、電源管理選項等重要參數的信息，以及芯片組固件的重要更新說明。
- I/O端口和支持功能：詳述主板上的各類I/O插槽（如PCI-E插槽、AGP插槽、IDE/SATA接口、PS/2接口、COM ports等），以及其他附加功能如AC'97音頻控制、整合網絡接口等。
- 內存控制器詳細信息：包括內存條的工作模式選擇、內存帶寬計算方法以及如何優(yōu)化內存性能等內容。
- 兼容性和兼容硬件列表：列出KT266支持的各種外圍設備和擴展卡類型及其相關驅動程序要求。
由于實際的產品手冊可能已經過時，獲取最新的技術規(guī)格和使用指南建議查閱VIA官網或者第三方電子技術資料庫以獲得最新版本的相關內容。
