When we run a computer with an operating system that is working normally, we probably rarely think about the Start-up DOS. But we will begin to feel the importance of the Start-up DOS when there is a problem in our computer's operating system. Nowadays, when disks are not found again, the CD became a practical option to create a DOS start-up media.
MS-DOS Boot CD is a medium used to boot your computer when it begins the startup of the Windows operating system and run some other utility programs such as disk fragment, virus scan, etc.. MS-DOS startup CD contains the programs and DOS commands that are compacted or compressed. It should be noted, that every operation system has unique characteristics. This means that the CD Boot also vary in accordance with the corresponding OS, as this Boot CD will only run on a computer that has a built-in programs that match requirement of the boots CD.
Some use the DOS CD:
- Install OS
- Modify OS
- Data Recovery
- Data Cleansing
- Disk Format
- Loading Game
- Troubleshooting software and hardware
Steps to create MS-DOS Start-up CD:
Place a CD into the computer’s CD-ROM drive.
Access “My Computer” through the icon placed on the desktop screen or by selecting it from the Windows “Start” menu.
In the “My Computer” window, point the mouse at the icon of the computer’s disc drive where your CD is. Right-click on the icon, then select “format”.
Once “Format” is clicked, a window box will appear. Options are provided in the Format window wherein users can choose from a variety of actions. Check the box that indicates “Create an MS-DOS startup disk”.
Click the “Start” button after checking the “Create an MS-DOS startup disk” box.
Users may also copy additional files to their boot CDs. Files added to boot CDs are programs or processes that the user chooses to run upon the system’s startup phase. This is done to support the operating system in launching other applications or utilities such as Anti-virus software and hardware drivers.
There are also several types of boot CD that have content specially designed for different operating systems. The required programs in a boot CD include (1) command.com, (2) io.sys/ibmio.sys, and (3) msdos.sys. These processes must be compatible with your version of the operating system.
