选择存储设备后,BIOS 在其上加载 MBR (Master Boot Record),运行操作系统加载器。在 Linux 中,操作系统加载器称为 GRUB (Grand Unified Bootloader); GRUB 加载配置以及在配置中指定的操作系统内核和initramfs。内核存储在 vmlinuz 开头的文件中,初始引导镜像存储在 initramfs 开头的文件中

U-Boot 的全称是Universal Boot Loader,其作用就是引导系统。对于我们熟悉的 PC,上电后,通过 BIOS 引导操作系统 (Windows、Linux等)。对于嵌入式系统一般将这个引导程序称作 BootLoader,U-Boot 就是目前使用得最广泛的 BootLoader。 在前面的文章中,QEMU直接引导鸿蒙系统的 Linux 内核,这种方式缺少灵活性,关键是在实...

PC Boot and Linux Init Process: When a Linux computer boots it performs the following series of processes: BIOS: The Basic Input/Output System is the lowest level interface between the computer and peripherals. The BIOS performs integrity checks on memory and seeks instructions on the Master Boor...
