BIOS(Basic Input Output System)是主機板上固化的韌體,負責硬體初始化與系統啟動。合理調整 BIOS 設定能釋放硬體潛能、縮短開機時間、提升穩定性。以下 14 項經典優化設定適用於傳統 BIOS(UEFI 介面對應選項名稱可能不同),修改前請記錄原值,不確定的選項保持預設。
Standard CMOS Features → 無裝置的埠位 Type/Mode 設為 None/Auto,減少開機偵測時間。Advanced BIOS Features → CPU L1 & L2 Cache / Internal/External Cache → Enabled。Advanced BIOS Features → Boot Up Speed / System Boot Speed → High / Fast。Advanced BIOS Features → Boot Sequence / Boot Priority → 第一順位 Hard Disk / C:,第二順位 USB / CD-ROM(視需求)。Advanced BIOS Features → Floppy Drive Seek At Boot / Boot Up Floppy Seek → Disabled。Advanced BIOS Features → Above 1MB Memory Test / Memory Test → Disabled,大幅縮短 POST 時間。Advanced Chipset Features → Video BIOS Shadow / VGA BIOS Shadow → Enabled,提升顯示效能。Advanced Chipset Features → Video BIOS Cacheable / VGA Cacheable → Enabled,將 Shadow 區域納入 L2/L3 快取。Advanced Chipset Features → Cache Timing / SRAM Timing → Fast / Fastest。Advanced Chipset Features → SDRAM CAS Latency Time → 3。舊式記憶體設 3 較穩定,優質記憶體可嘗試 2/2.5。Advanced Chipset Features → DRAM Clock → HCLK+33(記憶體頻率 = 系統外頻 + 33 MHz)。Boot → Fast Boot / Quick Boot → Enabled,跳過部份硬體檢測。合理調整 BIOS,讓老電腦也能煥發新活力!
