什麼是 BIOS?

BIOS(基本輸入/輸出系統)是一種固件形式,它告訴計算機的操作系統如何正確運行。它包含有關如何控制各種硬件組件(例如硬盤、鍵盤和顯示屏)的說明。除此之外,它還可以提供用於自定義系統設置和管理安全功能的選項。

BIOS 是如何工作的?

BIOS 的工作原理是在系統啟動時執行存儲在其內存中的指令。這意味著連接到計算機的所有設備(從鼠標和鍵盤到硬盤和顯卡)正常工作至關重要。一旦檢測到某些組件,BIOS 就會為它們分配特定的資源,例如中斷或內存地址,以便它們正常運行。

為什麼我需要 BIOS?

如果您希望計算機正常工作,那麼擁有 BIOS 至關重要,因為它允許您的操作系統(無論是 Windows 還是 MacOS)訪問與其連接的所有硬件組件。如果沒有這個軟件,您的計算機將無法啟動,這將導致其許多功能無法使用!

UEFI BIOS 是什麼?

UEFI(統一可擴展固件接口)是傳統 BIOS 的更新版本,專為現代計算機而設計。它提供對 64 位 CPU 架構的支持,並利用比標準固件更大的存儲容量,支持更高級的功能,例如安全啟動技術,有助於防止啟動過程中的惡意代碼執行。

我可以使用 BIOS 執行哪些常見任務?

大多數現代主板都提供一系列可定制的選項,您可以使用 BIOS 執行許多不同的任務,從微調超頻等性能設置到設置密碼以訪問機器功能的某些區域。通常還有一個區域,您可以直接從固件本身檢查和更新驅動程序,而不必單獨通過 Windows 或其他操作系統!

如何進入 BIOS 設置?

通常,您需要在啟動計算機後立即按特定的組合鍵才能訪問 UEFI/BIOS 設置屏幕;但是,製造商之間的這些有所不同,因此您可能需要查看機器隨附的文檔或在線搜索,具體取決於您安裝的主板類型!

我可以使用 BIOS 菜單自定義桌面嗎?

是的 - 根據您安裝的主板類型,UEFI/BIOS 菜單中應該有可用的選項,允許您自定義桌面環境的某些方面,例如風扇速度/噪音水平和照明方案等!

每次升級硬件組件時都需要新固件嗎?

否 – 每個設備都應保留自己的固件,除非另有明確說明;然而,有時仍然需要更新每個組件的單獨驅動程序,以保持一切以最佳狀態運行。此外,定期檢查 UEFI/BIOS 本身是否存在任何新更新可能有助於確保較新硬件型號之間的兼容性,因此在進行涉及硬件升級的任何重大更改之前,請始終保持此選項處於打開狀態!

我的 BIOS 會影響計算機的性能嗎?

是的 - BIOS 可以對計算機的性能產生直接影響,因為它包含驅動各種硬件組件(例如磁盤驅動器和顯卡)所需的指令。如果這些設置未經過優化或者隨著時間的推移而損壞,則可能會導致系統速度降低,甚至在某些情況下不穩定。

更新 BIOS 安全嗎?

更新 BIOS 通常被認為是安全的,前提是您在執行此操作時要小心並嚴格遵循所有製造商的指南。在進行升級之前,檢查新版本固件與現有硬件之間是否存在兼容性問題非常重要;但是,如果操作正確,那麼升級應該會帶來多種好處,例如提高穩定性、提高性能和更好的系統安全性!

存在哪些類型的 BIOS?

BIOS 主要分為三種類型:最初的 IBM PC (1984)、AWARDBIOS (1986) 和 UEFI/EFI (2005)。IBM PC 的設計追求簡單性,而 AWARDBIOS 在計算機變得越來越複雜的情況下提供了更高級的功能。至於UEFI/EFI,這種類型的固件主要是因為它能夠支持64位CPU架構以及比傳統BIOS更大的存儲容量而被實現!

什麼是CMOS?

CMOS 代表互補金屬氧化物半導體,與 BIOS 一起使用,以存儲與配置設置相關的數據,例如日期/時間和連接的外圍設備,這些數據需要在重新啟動時保留。此信息存儲在主板 RAM 模塊安裝位置附近的板載芯片上;然而,與標準硬盤不同,CMOS 不會跟踪已刪除的文件,因此在嘗試涉及此區域的任何重大更改之前,請務必確保備份所有相關信息!

我應該多久更新一次 BIOS?

建議您僅在絕對必要時更新 BIOS,因為安裝新固件會帶來一定的風險,例如由於不兼容而導致某些組件變磚或損壞。更新發生的頻率可能因係統而異,具體取決於應用了多少自定義以及需要安裝新驅動程序的頻率;然而,大多數用戶最多每 6-12 個月才需要一次!

更新 BIOS 是否存在任何風險?

是的 - 雖然安裝新版本的固件可能會帶來許多好處,例如提高穩定性、提高性能和更好的系統安全性,但執行此任務時仍然存在一些風險!由於不兼容,可能會出現某些組件變磚或損壞等問題,因此請務必確保在採取行動之前正確閱讀任何潛在問題 - 特別是如果更新是可選的而不是強制的!

我應該重置 BIOS 嗎?

如果您在使用某些組件時遇到問題或想要確保所有設置都恢復為默認值,則可能需要重置 BIOS。這樣做可以幫助消除由錯誤配置引起的任何潛在問題,但只能在備份任何重要數據後才進行,因為該過程可能會導致不穩定甚至損壞某些組件!

啟動菜單有什麼作用?

啟動菜單是 UEFI/BIOS 設置屏幕中的一個區域,可讓您控制計算機的啟動方式。您可以從許多不同的選項中進行選擇,從以安全模式啟動(防止任何程序運行)到選擇內部安裝多個驅動器時從哪個硬盤啟動。它通常還提供與系統安全相關的附加設置,例如啟動時直接啟動到管理員預定義的配置文件!

我可以使用 BIOS 對計算機進行超頻嗎?

是的 - 此選項通常在 UEFI/BIOS 的“高級設置”區域下可用,允許您將處理器速度提高到默認設置之外,以便從計算機中獲得更多性能。但請注意,超頻可能會產生嚴重後果,具體取決於您的超頻程度 - 只要您在開始此旅程之前研究涉及的內容並採取適當的預防措施,那麼超越某些限制就不會有任何問題!

如何重置 BIOS 密碼?

如果您忘記了 BIOS 密碼,請不要擔心 - 根據您安裝的主板類型,重置 CMOS 或清除 NVRAM(非易失性 RAM)通常可以解決這個問題。然而,此過程因機器而異,並且通常需要物理篡改,因此請務必在採取行動之前閱讀製造商指南!

什麼是混合關機模式?

混合關機模式是 Windows 10 某些版本中提供的一項高級功能,它通過休眠傳統的關閉過程來提高系統關閉速度。這意味著啟用後,當時運行的任何應用程序都將自動存儲在內存中,從而與正常退出時完全關閉所有內容相比,它們下次打開速度要快得多!
