想避免購買主板時被不良商家誤導？掌握主板開機畫面顯示的代碼含義，就能輕鬆辨別晶片組型號、I/O 晶片、廠商代碼與主板版本。本文整理經典主板 BIOS 開機代碼對照表，助你一眼看穿主板真實身分。
在 BIOS 自檢過程中，顯示卡資訊之後通常會出現系統資訊。主板型號常顯示於第三行，例如 TRM-P5MVP-A4-V1.01（其中 TRM 為主板品牌縮寫）。最底行則顯示核心資訊，格式類似 07/30/1998/-VP3-586B-W877-2A5LETGAC-00。
2A5LE：晶片組代碼，代表 VIA Apollo MVP3。TG：主板廠商代碼，對應 Tekram（建邦）。AC：主板具體型號代碼。| 代碼 | 晶片組 |
