Speaking of Parameter Segments ...
Do all related (P01 <-> P01, P59 <-> P59) OS'es read and write the parameter segment the same??
Meaning each data element is written to the same address, in the same format so it's readable by all relevant os'es.
Thank you!

Re: Parameter Segment
There are 2 different formats. Speaking only for vin, seed-key and some other stuff that is prior to first a550 checkword.
First is pre 00 OS from the early style 512kb pcms, The second is from 0411 on and 1mb pcms.
The data after that, case,theft relearn and so on can vary and be OS specific but for flashing more important is the first part, till a550.

Ok, I know, you know this shit inside and out, so I can only assume you had a brain fart and meant A5A0 not A550, for I cannot find A550 within 16k of the beginning of the parameter segment in any file I've looked into.
Do you by any chance know where (address) in a particular os (like: 12587603) the parameter read/write code is??
And just to let it be known, I'm looking at this from an OS change point of view ... What remains valid, what becomes (for all intents and purposes) corrupted information.
Again, Thank you very much!

Re: Parameter Segment
The checkword is a5a0[On very rare virgin pcms it can be fffe-or something like that]. I guess I mistype it. I have seen some piece of code that is copied to ram and executed from there, while the parameters are updated, it is hard to find it now. I guess that is what your looking for. The first part is valid for all Os[TILL first a5a0]. After that it can be OS specific.
