I found a lot of instance when searching for the above. I attached a screenshot as I am not sure if all entries are relevant. I see CrossDOS, MS-DOS etc... (01.png).

I also did a quick search for 44 4F 53 01 00 00 00 and I found five instance of this in the image file at the following lines:

0007e000
003f0400
le94cc00
5a373a00
6c3ec00

Now I just have a question and I promise this is one of the last ones before giving up; How do I determine Cyl (for LowCyl and HighCyl) from the line numbers? Or it is not something that strait forward?
