One simple question about how the hard disk works.
Playing a at486 with msdos 6.22, I've noticed that when you make some change in the hardisk, a diff file is created, and if you delete this diff file, all the changes are lost.
Is any way to integrate the diff file in the chd? I ask this because I add files to the chd converting it to raw and using WinImage, so when I put the chd back in the folder, an error message "invalid file parent" appears and I have to delete the diff file in order to get the machine working...
