What do you do with that information? I have seen images of the "Generic FlexLM Crypt Generator v0.5 by Haldir" posted in other threads on the eevblog forum, but have never found any references to that anywhere else on the net. Where can a copy of that tool be found?

Sorry, corrected the reference. The 16700 seeds are posted in another thread.
Yes, you can use them as you're supposing. The tool is available on the net, just needs some googling...

With help from another forum member, here is how to fully enable a 16911A card.
To Enable 500Mhz Turbo: Change 0x000A to 0x01 , increment value @ 0x000C by the value added to 0x000A
To enable Max Sampling, Change 0x000B to 0x04 , increment value @ 0x000D by the value you incremented at 0x000B
For example on my two cards i did tests on: ( that i read the eeproms on )
0x00 0x02 0x16 0x20 [ stock 250mhz/16ms ]
0x01 0x04 0x17 0x24 [ fully enabled ]

FYI, the easier option, is to generate a signed .lic file in the correct format, the tools are on the net, but i cannot download them ( i don't have enough rep points ) --

This is just a quick message, for those with "the tool", (many thanks to those who helped) this attached file I found in the Agilent LA installation directory may really help you.
Just pick which software or hardware options you want to add and rerun "the tool". :-/O
For SW, take the first line of each paragraph with your HOSTID=ANY
e.g. xilinx_fpga_dynamic_probe
or Signal_Extractor
You'll need to ensure the appropriate packages are installed.
You can add as many as you one in one file.
For HW, it's the first section
e.g. 16910A-032
Seems to support many many types of mainframe cards or systems.
All the best,
Dan

I recently picked up a 16702B... first of all, thanks for the resistor change info! I "upgraded" my 16750A, 16750B, and 16533A cards.
Just wanted to add one thing that I hadn't seen this mentioned... it looks R65 and R66 differentiate between the 'A' (R65 populated) and 'B' (R66 populated) versions.
When I initially compared the 16750A vs. 16750B side-by-side, I noticed that difference (pics attached). As a test, I populated the 16750B with the resistors described for the 16752A, and the card wasn't detected (showed an empty slot). Then I swapped R65 and R66, and the board showed up as a 16752B. So, it looks like the rest of the resistors are the same for the 'B', but R65 and R66 must match the actual type of board.
I guess that also means there's a difference, though I'm not sure what it is (I haven't done an in-depth comparison between them). Maybe just a minor chip or firmware change that makes them incompatible, though equivalent in performance?
Edit: I just looked at the cards, and the one difference that jumps out at me is that the 'A' uses XCV300 FPGAs, and the 'B' uses XCV300E FPGAs. The Virtex-E is a 1.8V FPGA instead of 2.5V of the original Virtex. Additionally, while the part number sounds like they'd be basically the same FPGA, the 300E has more logic resources than the 300, so they almost certainly require different bit files, which the mainframe would need to be aware of. So, I'd guess the 'A' to 'B' was simply a change to the Virtex-E due to the original Virtex going obsolete.
