Yes, but how? I don't know how since the flash drive isn't accessible on my
FDOS PC.

Sounds right.

I went to that site. I D/L the "all" file, which seemed cool to me, since it
wasn't that big (~400k) 2ut I didn't see any file/utils that would apply to my
USB FD (flash drive) Boot/access ordeal.

Good to know, thanx.

Hmmm, I don't see this as a working solution. Nevertheless, good to know.

I'm banking on any FD, even in DOS, is at least faster than floppies. Is that
not the case? I'm hoping so, but even if not, the capacity advantage more than
compensates for any lack of speed, to me anyway.

I do use an SSD, but not in my FDOS PC.
