Once again,
the  options code are stored in a 1-wire eeprom,  with the same code xxxx-xxxx-xxxx-xxxx give by well descripted above procedure...

now the question is:

if i store manually  the code into the 1-wire eeprom :-/O, the  software 8.x.x.x could accept the options?

Could be true for this reason, if i've an instrument with the 7.2.0.5 software version (for example...) i buy an option, that software store this option into the 1-wire eeprom and everythings run
Now i upgrade the software with a 8.x.x.x version, my option must work again maybe with the same code  :-+

which eeprom? on the pci card? or on the acquisition board below?
if something can select, how cant it be intelligent? if something is intelligent, how cant it exist?

Fresh news about 8.x.x.x and options...
Online i've found an WS24MXs with 4 option keys , LBW (is WS24..) ATP,HDTV,MSURF and software version 8.1.2.0.

i run for each keys the command  "validate", it return the correct scope id and option name!! :scared:

for example the key "67f2-9132-b9fd-247g" is MSURF option and it works on 8.1.2.0  !! :-DD

now the question is: maybe, with 8.x.x.x they change how the options are accepted and stored but the options keys are the same. Is true?? :o

The point is that 'old' options are not 're-encoded' by default when upgrading (as far as I know)... it's not even known whether old options are affected at all by the new encoding scheme(s)...
It's not 100% clear neither from what exact version things changed... ever tried the latest one (8.6) ?

But it would be interesting to see if you could wipe one of these 'old' options, and re-install it with the same key ?
If you have 8.x, could you try installing some (recent) decoding option (like CAN-FD) generated with the pre-8.x keygen ?

And for sure all post-8.x options are unusable, as the options file (i.e. the database with all possible options) is encrypted with a new scheme.

 :popcorn:  Lecroy uses a DS2433 EEPROM on their interface boards, that's known for years...

Hey,
can anyone confirm that the DEV key can be deleted?
I have to delete an grayed out key!
What function does the DEV key/option provide furthermore?

Thanks in advance!

Has someone found an update to list.py that can decrypt/list the options from FW 8.x.x.x onward?
