How to install pure DOS under WINNT/2K/XP

&http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp; As you know, there's a "command prompt" in winnt/2k/xp that looks like an MS-dos window in win3.x/9x. However, they are completely different. Win3.x/9x is a GUI interface enhancement program for large protection modes running in MS-DOS, while WINNT/2K/XP is an independent operating system based on powering and NT components, so there is an essential difference between them. The real dos is pure DOS, such as MS-DOS and Pc-dos, and the command prompt in WINNT/2K/XP is just a "Winnt system console" with a section of "DOS Virtual Machine" features. Since it is virtual, the effect of nature does not really good. Therefore, when this "virtual DOS" fails to run the DOS program properly, only real DOS (such as MS-DOS 7.10) is used to run them.

Since WINNT/2K/XP does not have DOS, you can only use dual booting if you want to install a pure DOS system with your hard disk after installing these operating systems. Many users know that winnt/2k/xp startup often appear a menu, from which you can select the operating system to start. However, sometimes this menu does not have the "DOS" option, even when the boot menu does not appear at all (if you choose to keep the original operating system when you install WINNT/2K/XP, the original operating system option will appear in WINNT/2K/XP's boot menu). So what should we do? The following is a description of how to install DOS after installing WINNT/2K/XP.

DOS boot sector and boot files are required for the start of the system. The DOS installer automatically rebuilds the DOS boot sector and boot files when it is installed, so that DOS can be started after installation. However, for older versions of DOS, such as MS-DOS 6.x, their installer overrides winnt/2k/xp boot information, causing WINNT/2K/XP to fail to start. This is also the case with command transmissions such as the SYS with DOS. Therefore, in order to enable both DOS and WINNT/2K/XP to start, it should be done in a better way, or automatically with a DOS installer that automatically dos and WINNT/2K/XP dual boot.

MS-DOS 7.10 is currently the most powerful, practical, and compatible DOS. And because it fully supports large hard disk, large memory, long file name (LFN), FAT32 partition, may directly start win3.x/9x and so on, so very practical. and its installation program on the full support and winnt/2k/xp coexist. "MS-DOS 7.10 Full installation Version" (can be downloaded in "DOS system") in the installation allows the system to automatically complete the installation of the WINNT/2K/XP under the full DOS version of the operation, and automatically implement DOS and WINNT/2K/XP dual-boot. Because the MS-DOS 7.10 Full installation version is very powerful and practical, it is recommended to use.

However, if the primary partition of the hard disk (usually the C disk) is in NTFS format, it is not possible to install DOS directly because DOS does not directly support the NTFS format. This can be accomplished with a number of boot managers, such as Spfdisk. With the multiple Boot Disk Manager set up the system partition, the direct installation of MS-DOS 7.10 to achieve coexistence with WINNT/2K/XP.

In addition, in addition to installing DOS or using a real DOS boot floppy boot dos, you can also use the virtual floppy image of the method to start the DOS, that is, from the WINNT/2K/XP boot menu directly start the Virtual DOS boot floppy disk DOS, the equivalent of starting from a DOS boot floppy disk. Can be achieved by using software such as Vfloppy, GRUB for NTLDR, and so on. However, please note that using a virtual floppy or a real floppy disk to boot to DOS is not installed DOS, if you want to really install DOS, you need a DOS installer to install automatically.
