bootloader
引导程序(英语:bootloader)是指在电脑系统中负责初始化周边设备、启动操作系统的程序。
操作系统在硬盘上,主板上电到读取硬盘之间还有一段路要走。
- 第一阶段引导加载程序的例子包括BIOS、UEFI、coreboot、Libreboot和Das U-Boot。
- 第二阶段引导加载程序,如GNU GRUB、rEFInd、Windows Boot Manager、Syslinux和NTLDR
在个人电脑 PC 上:
BIOS(英文:Basic Input/Output System),即基本输入输出系统, is a type of firmware used to ……
The BIOS in older PCs(个人电脑) initializes and tests the system hardware components, and loads a boot loader from a mass storage device which then initializes a kernel.
统一可扩展固件接口(英语:Unified Extensible Firmware Interface,缩写 UEFI) 是 PC BIOS 的继任者。
In computing, [firmware][firmware ] is software that provides low-level control of computing device hardware.
在嵌入式设备上:
Das U-Boot is an open-source boot loader used in embedded devices
- to perform various low-level hardware initialization tasks
- and boot the device’s operating system kernel.
U-Boot 既是第一阶段引导加载程序,也是第二阶段引导加载程序。
