Looks like the algo is $5b for you pcm. Not sure what algo is used for default p12 in pcmhammer.

Can you run this script with this program. It will test if pcm uses standard algo.

post results here.

Here is the binary from that pcm if it helps

The algo used is 28, default for ls1 pcm. 5b is correct for p12, so I suspect OS is not in the list and program defaults to ls1 operation.

Maybe some manual override for pcm type can be added until a proper list of OS is build.

it does identify as a p01-p59 upon startup of hammer

Thanks for confirming! I've committed the change.

I think we also need to remove the request for hardware ID on get properties. I took it out on one of the test builds, but it was missed in the development branch that turned in to 021. I dont think there is any value in hardware ID because it doesnt work on the P10 (though thats probably fixable if we wanted to), but nobody knows the hardware IDs, and its part of the OS, and it does not query the actual hardware the OS is on. If you write one osid and param block to another pcm, the ID will follow the OS thus is no longer correct. OSID and Service number on the sticker seem to be the best identifiers and are what people use.

12589586 is also apart of the p12 line up, can I get a copy of a bin with 12601904 to try and update my os?
