从这篇博客 了解到initrd.img文件的开头有一些microcode 博客中的一条管道命令太长,为了简化寻找问题,我拆开分成3步骤。首先,把开头那段mircorcode去掉。然后余下部分,我输出到新文件new.gz如图可见,余下的数据,分成4段,2种压缩格式。 我尝试用xz解压失败,好像因为该文件是多种格式的 linux编译安装linux-kernel 有...

The first cpio contains only the AMD microcode. The second cpio contains only the Intel microcode. The third cpio contains firmware files and kernel modules. Extract the content of the initramfs cpio to the initrd subdirectory on an Ubuntu 24.04 system: $ 3cpio --extract -C initrd /boot/init...
我们可以使用 msoffcrypto-crack.py 破解密码并新建一个没有密码保护的同名文件：
With RHEL 7 the initramfs file now stores both CPU microcode and the initial boot image in the one "combined" image file. The CPU microcode is stored with CPIO compression, then the boot image is stored with its own separate compression. In this article I will share different methods to ex...
