Debug
Posted by admin on 07 Mar 2008 | Tagged as: dos
Debug is a command that you will find in DOS, MS-DOS and Windows. It is known to run on the application “Debug.exe”. This command can help the user by acting as a dissembler as well as an assembler. Simply put, this only means that with the help of this command, the user can actually check the memory of the computer, edit and make changes if necessary, which can further make it easy for the user to run file types like com, exe, etc. In addition, to facilitate easy access to particular disk sectors, memory sectors, specific ports, the debug command is made up of several sub commands.
Originally, the debug command was written by Tim Paterson because it was needless to say that all computer systems needed a maintenance tool and the debug command provided just that. So one thing that you should know is that you should always use the debug command carefully. Because any mistake on your part can result in the loss of sensitive data. Therefore, it is important that you deal with the debug command only if you are well versed with programs or under the guidance of a tech support. You have to know that when you are about to use the debug command, the effect that it is likely to cause may slow down your systems. The computer may slow down if you are debugging on a AS5800 or it may even hang in some cases.
In order to make the debug process easy, it is advised that you check if the CPU load is enough for you to perform the operation. This is the syntax that you use for the debug command: debug [[Drive:][Path] FileName [parameters]]. If you continue to debug repeatedly, you will surely find that your PC will hang. Also, always remember that if you find that the debug output is too large, you can simply use the vty ports. So simply put, debug command is nothing but a tool that that informs the user about the events and protocols of inter-networking activities during a particular timeframe.
How to Reformat a Hard Drive

Trying to find an answer to how to reformat a hard drive? Well, before I actually tell you that, I would first like to shed some light on the repercussions of such a move. The first thing I would like to tell you is that when you reformat a hard drive what happens is that all the data that might be there on the drive gets erased automatically. You may already be well aware of this, but I am not to be blamed because I am quite sure that there are thousands out there who don’t have a clue. I am just taking the right precautions because I don’t want people chasing me down for the loss of important files and folders that they might have had in their hard drives.
For reformatting secondary partitions on your hard drive, you just have to right click on that particular partition, select the format option and click on ‘start’. However in case you wish to reformat your entire hard drive, then you will require a CD of Windows Operating System or a bootable MS-DOS Floppy or CD. Both of these will force your system to boot from the CD and all you will be required to do is follow the instructions and keep selecting the options that you need. Eventually you will come across the format option, which will prompt you to select between NTFS and FAT file formatting. Since NTFS is the advanced file allocation system, I would recommend that you select NTFS.
What you wish to do with your reformatted hard drive is up to you, but the one thing you can be pretty sure of is that the hard drive will then be completely clean and ready for use. When you finally install Windows, you will notice that your system on the whole, has also become a lot faster and smarter.

autoexec.bat & config.sys problems
Posted by admin on 16 Oct 2007 | Tagged as: dos, configuration, operating system, windows, computer
The autoexec file was originally created for MS-DOS and Windows 3.x operating systems. Autoexec.bat was used in conjunction with the config.sys file as an easy way of loading the files that were required for various hardware devices and the operating system to run properly. In later revisions of MS-DOS and Windows 3.x these files were required in order for the operating system to load at all. In newer versions of Microsoft operating systems, these files are no longer required to load the operating system, however, a user may need to edit the information within these files from time to time.
Now, just to be safe, we recommend that before you edit the autoexec.bat or config.sys files that you create a copy of the original ones with a different name so that they can be recovered in the case that you make an error and things do not work properly after.
The most common way of editing the autoexec.bat and config.sys files is by using the MS-DOS command Edit. In order to edit these files you simply need to type “edit c:\autoexec.bat or config.sys” into a MS-DOS command prompt. However, on newer computer systems, the more common way to edit these files is to click on “Start” and then “Run”. Now you will want to type sysedit into the dialog box provided and click on the “OK” button. This will quickly display the System Configuration Editor within which the autoexec.bat, config.sys, win.ini and system.ini files are displayed for easy editing.
If you want to remove a line from one of these files, the most advised method is to use the remark command “REM” in front of the line you no longer want to execute. This will tell the computer to ignore this line when the operating system is loading, but also will allow you to easily remove your remark command to include the line again in the future if you do not get the result that you want or if you wish to use the line again at a later time. This will help you to easily restore that line of code without having to worry about where in the file it should be placed or the syntax that it should be written with.
With the increasing number of programs that are being loaded by an operating system when it first starts, getting additional memory is always as big advantage for any computer user. There is a way in the config.sys file that you can tell the operating system to load the files more efficiently into memory, which will help you have more memor for other programs and games on your system, especially in MS-DOS computers. In order to do this there are three lines that you will want to have at the beginning of your config.sys file:
DEVICE=C:\Windows\HIMEM.SYS
DOS=HIGH,UMB
DEVICE=C:\Windows\EMM386.EXE NOEMS
By using the DOS=HIGH, UMB command on the second line, you can potentially save memory because it is now loading DOS into upper memory before loading the memory manager. The first and third lines cannot be loaded into the upper memory areas however as they are the memory managers themselves. The best technique for saving memory is to load all of your devices in your config.sys file and autoexec.bat file into high memory.
