Acronis Disk Director Suite supports the following versions of DOS-type operating 
systems: 

•  MS-DOS 5.x–6.x 
•  MS-DOS 7.0 (not a separate product but is included in Windows 95) 
•  MS-DOS 7.1 (not a separate product but is included in Windows 95 OSR2/98) 
•  MS-DOS 8.0 (not a separate product but is included in Windows Me) 
•  PC-DOS 5.x–7.0 
•  DR-DOS 7.x 

 

Acronis Disk Director Suite will detect MS-DOS 7.x/8.0 as a separate operating 

system only if it is not a part of the installed Windows operating system, but was 

instead installed on your computer with help of the SYS command. 

Acronis Disk Director Suite recognizes the following special cases: 

•  MS-DOS 5.x–6.x or PC-DOS that has Windows 95/98/Me installed over it 
•  MS-DOS or PC-DOS that has Windows NT/2000 installed over it 

 

Acronis Disk Director Suite may not support some DOS versions (for example the 

Japanese version). In these cases, system and configuration file lists should be 
edited (for example, font files should be added) to avoid conflicts between different 

copies of these operating systems. 

DOS boot sequence consists of the following stages: 

1. 

The boot sector (after being loaded into memory and receiving control) 
scans the root folder for the first DOS file. Upon finding one, it loads the 
first several sectors (the loader) into memory, assuming that they are 
positioned contiguously on the disk, and passes control to the loader. 

2. 

The loader loads the rest of the first file (boot manager) into memory and 
launches the program. 

3. 

The boot manager initializes the memory, scans the partition structure and 
assigns letters to partitions, defining the DOS boot partition on the way.
