Hello, i know the thread is old, but i m facing the same issue.
I bought a SilverStone SST- ECS04 with LSISAS2308 controler (LSI 9217-8i).
I wil be used to create a raid 1 in order to install Esxi 6.7, but i am not able to see it under the POST process.
The card is installed in a Z370M-ITX/ac. so after google the issue, i see this topic, so a i tape over the 2 pins but not luck, still undetectable.
I tried in an other PC and yes, this do the trick in an other motherboard (Z170 PRO GAMING).
So, i would like to know if by chance, someon
