Okay, here's the full decode.  I found a cool site online that does a lot of checksum calcs...but I cannot find the one used on this!

It's not a 2's complement or simple stuff, that I can see.  MacOS Word doesn't allow me to mix my own highlights, so they are reused every line (same ordering) just to help visually distinguish the different variables.

   

So that's at least the basics...I copied Vvuk's formatting from the post I previously linked to for familiarty and easy comparison: https://forums.irixnet.org/thread-2164-p...l#pid22877

Thanks!

@@@UPDATE@@@
Looking at Jwhat's great posted log here: https://forums.irixnet.org/thread-2164-p...l#pid22578

It shows offtsets.  so far I have tracked flash "magic number" (4a 46 4b 53 57 43 53 4d) to Two locations in my PROM dump!

Offsets: 0x00087ac0. and 0x00165c70


Jwhat: Do you have the full PROM HEX dumps from your 600Mhz to 800Mhz Fuel Reflashing?  Can you give them to me?  I'd like to see any diffs for myself?
