console and they’re erased after the boot process finishes. However, this usually isn’t a problem because each script typically writes its own log. Some versions of init, such as Upstart and systemd, can capture diagnostic messages from startup and runtime that would normally go to the ...
boot 的设计中需要将 u-boot 的镜像拷贝到 ram(sdram,ddr...)中执行,这里表示复制的开始地址 */*(.vectors) /* 中断向量表 */CPUDIR/start.o (.text*) /* CPUDIR/start.o 中的所有.text 段 */}/* This needs to come before *(.text*) */.__efi_runtime_start : {*(.__efi_runtime_st...

6. init 执行 run-level 下各个服务并启动 (script 方式); 7. init 执行开机后自动运行脚本 /etc/rc.d/rc.local 文件; 8. init 执行虚拟终端机控制程序 mingetty 来启动 login 程序,最后就等待用户登入啦; 如图: 17.1.2 centos6启动相关的配置文件 ...
The init program is typically a shell script. Note that the boot process takes longer, if an initramfs is used. 没事别看: initramfs - Debian Wiki initramfs-tools apt install initramfs-tools update-initramfs 命令 本命令由initramfs-tools提供 manages your initramfs images on your local box. (啥...
BIOS-runtime服务按照boot启动顺序搜索设备,寻找BBR 由于BIOS功能使用上的不同,它由两个部分组成:POST和runtime服务。POST完成后,它将从存储器中被清除,但是BIOS runtime服务会被保留,用于目标操作系统。 为了启动操作系统,BIOS的runtime服务将搜索那些激活状态的或是可引导启动的设备,搜索的顺序则由CMOS设置决定(也...
