That worked! Thanks for the help. Now I'm tweaking my old code and just replacing my guestfs_mount() call with a hard-coded "guestfs_mount(g, "/dev/sda",'/"); Next task is to review my registry changes and see if those registries even exist in Win95. What this code does is open the image, tweaks some registry settings to use some "generic" drivers and uploads those drivers. With the goal of running the VM without resulting in a BSOD. But I might just try and remove all the "tweaking" and see if a Virtual Box VM can just boot up the image. Might get lucky. Besides - I doubt those drivers are Win95 compatible. I'll let you know how it goes.
