Hi, Can someone help me understand how to use the D-device? I can get results like the one shown using the H-device. However I cannot get the D-device to work. For instance the command ENTER "D5:HELLO.BAS" results in a 130 error, while the command ENTER "H1:HELLO.BAS" works fine. I also cannot access D-device drives from MyDos (v 4.50). When I try to get a disk directory of D5:*.* it results in a 163 error.
