早期Legacy BIOS會在DOS環境下, 透過指令方式, 或集結成批次檔 *.bat 以完成特定的自動化需求; 現在推動UEFI環境, 這是Built-in的 EFI shell, 要自動化也是需要批次檔 *nsh
當系統開機到 EFI shell時, 此時嵌入式作業系統會透過搜尋已定義好的path 找尋此檔 startup.nsh, 所以基本上來說Startup.nsh相當於DOS/Windows環境下的autoexec.bat，當跑完這個startup script之後, 會顯示如下的指令提示介面: (翻譯引用自Intel文件:Basic Instructions for Using the Extensible Firmware Interface (EFI))

| Legacy BIOS | UEFI | |
| 發明年代 | 1975 by IBM | 2002 by Intel |
| 程式語言 | 組合語言 | C語言 |
| CPU mode | 16-bit mode(Real mode) | 32/64-bit mode(Flat mode) |
| 記憶體定址空間 | ~1 MB | >4 GB |
| 支援硬碟分割格式 | MBR | GPT |
| 支援硬碟最大容量 | ~2 TB | ~9 ZetaBytes |
| 支援硬碟主分割區數量 | 4 | 128 |
| Boot Speed | 慢 | 快 |
| Boot Manager | Boot loader in MBR | Boot loaders in ESP |
| 硬體擴充方式 | Option ROM | EFI driver |
| 硬體資源控制 | Interrupt | Protocol/Driver |
| 安全機制 | TPM | Secure Boot |
| VGA BIOS | VBIOS | GOP |
| Bootable USB Flash drive | DOS | EFI Shell |
統一可延伸韌體介面（Unified Extensible Firmware Interface, UEFI）是一種個人電腦系統規格，用來定義作業系統與系統韌體之間的軟體介面，作為BIOS的替代方案。可延伸韌體介面負責加電自檢（POST）、連繫作業系統以及提供連接作業系統與硬體的介面。(參考自wiki)

3. Microseconds is in decimal units.
Examples:
