Yes, I did that with two of the zip archives, 1.1.0 and 1.7.4. I
understand that this deals with the mechanics. What I'm getting
at is more along the lines of "gee, there seem to be some naming
conventions going on here, maybe that differentiate between
a STA firmware and a PRI and maybe other kinds; but I've not a clue
what they would be." For example, if my intent was to upgrade the
STA but not the PRI; or whatever.
And the 1.7.4 zip had so many different files, I had no idea conceptually
what they would each be for (maybe there are two each for three
different kinds of cards? Point is, can't tell from names).

Ah! Great! Sorry if I missed these pointers in the list archive; believe
this would be exactly what I was looking for, but just couldn't come
up with it.

The 1.7.4.tar.gz archive from (in this case) your web site.

Ah! Outstanding! Thx. (Just to make sure my browser isn't flaky - those
details weren't in the readme last night, were they? If they were, I
need a new netscape).

I understand completely. Wasn't doing any complaining; just didn't
want to bollix up my stuff due to my own ignorance, and after a long
time looking, I still hadn't found enough info to feel reasonably
clear on the concept.
On that note: I greatly appreciate the amount of clarity you
and the other experts have had the time to shed, and your support
to the community on this topic. Without it, I simply wouldn't
be able to any of what I've done at home.
