Its "UcsiAcpi" SSDT (BIOS X96 01.05.01) matches what you describe for 8ED9: the mailbox is 0x30 bytes with 16-byte MESSAGE_IN/MESSAGE_OUT, _DSM function 0 returns 0x0f (functions 0-3 only), function 2 is a stub, and VERSION is written only on the EC response path (_Q27 -> UQDC -> UETO, copied from EC0.UB00/UB01). A PPM_RESET through function 1 completes in URST(), which sets RESET_COMPLETE directly without going through UETO, so it does not fill in VERSION either. I have not run your patch on the Fury yet, so this is based on the tables only. If an 8DE2 entry next to 8ED9 is wanted, I can test it. Thanks, Francesco
