4. Main Features and workflow of MBR
After the CPU is powered on, if it is started by the hard disk, the BIOS will read the Master Boot Record of the hard disk (in the 0 cylinder, 0 track, 1 Sector) into the 7c00 position, then, the control is handed over to the Master Guide code. Tasks of the main Bootstrap Code include:
Scan the partition table and find an active (bootable) p
source code is compiled, the root folder is generated. In fact, the files under root are the same as those in ramdisk. IMG. But here we will introduce how to decompress ramdisk. IMG:Copy ramdisk.imgto another directory, change its name to ramdisk.img.gz, and run the commandGunzip ramdisk.img.gzCreate a folder named ramdisk.Cpio-I-f ../ramdisk. imgNow you can see and operate the content in ramdisk.

loader. Many people think that this is the real part of the boot loader. It contains the part where the loader needs more disk space, such as the user interface and kernel boot program. From simple command lines to graphic GUI, these user interfaces are widely used.
Boot Loader is usually configured in either of two ways: either as the primary boot loader or as a secondary boot loader ).Main Bootstrap programIs the first-stage Boot Loader installed on MBR (see previous descriptions ).Level 2 Bo

Change Rate of derivative reaction
The derivative of a function at a certain point describes the change rate of the function near this point. The essence of the derivative is to use the Limit Concept to locally approximate the function. When the independent variable of a function produces an increment at one point, if the ratio of the increment of the output value of the function to the increment value of the

Of course, the mksysb image used for restoration should be newer. You can also use mksysb to install another machine, which requires some configuration, such as IP address, because almost everything on the original machine is copied to the tape.
