I'm pretty sure that call is the entire issue, as I wrote a little TSR that modifies the return value of 21/4408 to always be 1 (fixed) as long as there was no error returned (invalid drive or such), and it cures the install program's problem.
Actually, there is sort of an additional test that's done: on any drive that is considered fixed, it tries to open the file \t7g\install\hdisk.gjd, and if the file is found then that drive is used as the source drive. But because a CD drive is being considered removable, it doesn't even look on it for that file.
BTW, it just occured to me that Graeme Devine, the developer, used his initials for the data files. 😀
