Ghost creates a self-help F11 Recovery System

Some IBM models cancel the original Random System and drive recovery CDs, and then draw a hidden partition ranging from several hundred MB to more than 1 GB on the hard disk to store recovery data, when the system is started, the user restores data by F11. This method has advantages and disadvantages. The inconvenience is that it occupies a certain amount of hard disk space, and it is very troublesome to restore the system if the hard disk in the notebook is damaged. On the other hand, for IBM, the cost of two or three CDs can be reduced, and users can leave their optical drives and CDs when they leave the house. Once a problem occurs, the system can resume normal operation at any time by F11. However, it is quite uncomfortable that the F11 is restoring the system status at the factory time. The recovery process takes nearly an hour. Is there a way to put your own system in a hidden partition, then, what about F11 recovery when necessary? IBM has provided a Rapid Restore for users to use, but this software is very troublesome, requiring the system hard disk to be only one system partition, and the production time is also very long, the webmaster tried the software on several models (including T23 and A31P) and told them to buy the license.

At present, most users prefer to use ghost to back up the system, usually partitioning to file backup. This is a very fast backup/recovery tool that supports the compression function and comes with quite a variety of parameters, after a period of research on the F11 restoration function, the webmaster pressed countless F11 on his hard disk, restored countless times, and finally figured out the F11 restoration mechanism comprehensively, in addition, the system backed up with ghost is put into a hidden partition, so that when you press F11, ghost will automatically run to restore the system to drive C, which is fast and can be completed in a few minutes.

Let's talk about several concepts:
1. F11 only clears data on drive C and does not affect other partitions. However, we recommend that you back up data.
2. Hiding a partition is a system partition.
3. autoexec. bat is a DOS automatic batch processing file and runs automatically at startup.
4. A hard disk can have up to three system partitions, but only one of them can be activated. Fdisk can only create one system partition.

　　I. F11 recovery mechanism

F11 must be carried out with a BMGR tool from IBM. This tool kit is contained in hidden partitions. The Boot Sector of the hard disk will be automatically modified after the restoration process is completed, this mechanism is consistent with the "boot virus", so pressing F11 will trigger the "virus" attack ". During the "attack" process, the recovery process is to shield the extended partitions of the system hard disk, set the original drive C as a non-active partition, and then modify the hidden partition attribute to be hidden and activate it, in this way, the system will automatically start from the hidden partition (that is, the current start partition), run the corresponding batch processing file, format the original C disk, then copy the restored installation file to the original C drive and restart it. After the boot, the system and driver will be re-installed from the original C drive, and some factory settings. It is important to note that, after F11 is pressed, data is copied and restarted, the partition status of the system is restored to before F11 (starting from drive C and restoring hidden partition to hidden state, in this way, we can imagine putting our recovery system into hidden partitions and then creating an automatic batch processing file (autoexec. bat), after running, let the system automatically restart once!

After Disk1 is restored, we can see that the extended partitions in the original shard have changed to no partitions, and the original boot partition drive C is not started, but it can be seen that, the original hidden partition IBM_SERVICE becomes the start partition, which is visible.

　　Ii. How to view information in hidden partitions

You can use PQMagic to set the hidden partition attribute to non-hidden. After restart, a drive letter is automatically assigned to the hidden partition, you can view the file information in the ordinary partition. Another method is in Windows2000 (Professiona. or Server), but Windows XP does not work, whether it is Professional or the latest version. NET does not work. I don't know if MS programmers accidentally deleted a piece of code.

* Process: Run Control Panel> Administrator tools> Computer Management> Disk Management to view the partitions of each hard Disk. The IBM_SERVICE is used to hide partitions.

 

Now move the mouse over the partition and right-click the partition to view the menu. However, you still cannot view the content of the partition directly. The corresponding menu bar Expore is gray. The solution is simple. Just assign a drive letter to the hidden partition. Select "Change Drive Letter and Path..." in the pop-up menu ..."

Then select Add... Then assign a drive letter to it. just assign a valid drive letter to the system, such as I. Click OK. Return to the Management page and right-click the partition. Then, you will find that the menu "e" is available, after you click it, the resource manager is called to view the data in the partition. This is the information above the hidden partition. You can set this to Active in disk management, set the original boot partition to non-Active, and then restart to BIOS to set the disk to start from this disk, after startup, wait until F11 is pressed to start recovery. 　　3. Create your own F11 Recovery System After learning about the above principles, it is not very difficult to create your own F11 recovery system. First look at the preparation tool: 1. a dos boot disk with the basic DOS system and sys.com, preferably with the himem. sys file. Or a boot CD, but sys.com must also be available. 2. PQMagic5.0 or above and ghost7.0 or above (download from the download center on this site) 3,IBM's F11 restoration partitioning Tool When they are ready, they will officially start the "self-help F11" tour. 1. Of course, you have installed your own systems and software first. We recommend that you store your applications on the drive C as much as possible so that they can be used immediately after recovery. 2. Use ghost to back up a partition to a file. Generally, the backup file is stored on drive D or drive E (outside drive C ). 3. Run PQMagic. We recommend that you start it to DOS. In the following example, the webmaster uses the PQ5 version. The hard disk has only one basic DOS system and only one system partition. Of course, it doesn't matter if your hard disk has multiple partitions, but it should be noted that the hidden partition itself is a system partition, because we can only draw part of the space from drive C. We recommend that you create a new partition to hide the partition, but not from the extended partition/logical partition to create the partition, because it cannot be started. This is the hard disk status of the Webmaster: * After that, you must first set the Skip bad sector checks of General> Preference to hook Disk1 or/and Disk2 and then confirm, in this way, if the hard disk is normal, it will greatly speed up *. If the hard disk itself has bad sectors, do not select this option.
