Thanks for reply
https://www.memtest86.com/pricing.html
memtest 6 is a commerical product, and would not be
legal for me to include with my project. I've know that it
is available, but for $49 for a single license that could
not be included.
https://memtest.org/ has a file but is an iso.

Will have to see what it has? Don't see any UEFI option
on that site?
