The files were 1:1 "as-is" copied from the micron-webserver and original file names left intact.
I noticed that some md5-sums aren't properly formatted for UNIX-style, contain wrong file names or didn't exist at all.

So...my own checksums you can check and compare with the original for your convenience:

cat *.md5 && md5sum -c checksum.md5
