- My B: drive on my msdos3.3 machine has started acting funny. If I insert
- a floppy in it and do a DIR command and then insert another floppy and
- do another DIR command then the output of the second DIR command is
- the same as the first (yes, they should be different).
-
- I'm guessing that the "disk change" signal on pin34 is no longer working
- correctly.
-
- I have two questions:
-
- 1. Does anyone have a diagnostic program which can verify that the
- pin34 disk change signal is working or not working?
-
- 2. Is there any way to force msdos3.3 to ignore the pin34 signal and
- always throw away its buffer contents? If so, can I do this on my B:
- drive and not affect my A: drive?
-
- Note: this is a vanilla 386 clone box, and I'm not running any special
- disk caching programs or drivers.
