Hello out there,
I want to unmount / dismount a removable drive on Win9x. For NT type
OSes this seems not to be a problem (using DeviceIoControl with
FSCTL_DISMOUNT_VOLUME and others).
For Win9x these do not work. I found a (broken) link to using some old
Int 21h functions instead.
Hm, this is going to be fun. Does anybody have links to docs on
- how to access this Int 21h interface and
- (more specifically) on unmounting a device ?

Any help will be greatly appreciated
Helmut Giese
