very slight OT: creating a *bootable* MSDOS7 memstick

[Aryeh Friedman]

I have a *.exe that needs to be run in order to recover the firmware on one
of my SSD's that requires MSDOS7 to run.  I do not have a floppy drive and
I do no have any form of anything from Microslut installed or even in the
house.   How do I create a bootable memstick that contains this exe? (I am
on FreeBSD 12.1pl8-amd64)
