I'm assured by OpenBSD developers that any fdisk should suffice for any operating system. Having been repeatedly savaged by buggy fdisk programs, I find myself unable to give you carte blanche to try this.

@quotebot Fun fact: I once pulled apart the Windows installer (XP vintage). What I found was FDISK.EXE, DD.EXE, etc. Essentially, the installer depended on Unix tools to install the anti-Unix OS. (I then kept copies of all those because they were better than the native disk tools. Especially DD. Windows doesn't have that.)

I assumed this was a legacy of their original development of Window on a Unix system (Xenix, IIRC).

No SH.EXE, unfortunately.
