First, a little bit of information about my setup. My primary, active partition is located on drive C, which is a 160GB Raid Array configuration. Installed in this partition, is Windows XP MCE. Using Disk Director Suite 10 on the Raid Array, I created a separate partition using the FAT16 file system. The system automatically assigned the new partition the drive letter of "E". Next, I activated Acronis O/S selector. My question is how do I go about installing MS-DOS 6.22 to this newly created partition. Also, once it is installed, how do I get Acronis 0/S selector to recoginize it, so that I can switch "back-and-forth" between Windows XP and MS-DOS 6.22...Thanks!
