My 550 won't boot without the DIMM in, so it sounds like it's not

OK. That is a good data point. However, I don't know from what code
base that original wrapper was built from in order to debug further.
Did you save the original rom image that your device was shipped
with?
I do, but I'm not sure how complete it is since every time I've tried
to use it since first reading the ME doesn't seem to be very happy and
switches the laptop off after 30 mins. I'll forward it, presently.
I'd be curious to know if that matches the one found in the blobs
repo.

Did someone change the SPD eeprom address notation in pei_data

7-bit to 8-bit addresses? samsung/lumpy/romstage.c :

spd_addresses: { 0xA0, 0x00,0xA4,0x00 },
The 0xf0 handles the soldered down memory. I was looking at the
0x50
address as well, but I think that is correct (I'm looking at code
that I think is the wrapper that you guys are using). I could be
wrong though.
