I have just successfully finished installing Sierra on my old GA-G31M-ES2L Gigabyte board. Everything works wonderfully minus one little thing I can't understand...
I was trying to enable trim as my system drive is a Kingston SSD when I noticed that the SSD is, actually, not seen as a SSD. That is quite funny. It is super speedy as always but under its info in disk utility there is a flag stating "solid state: no". Checking the system report there is also no info regarding trim that makes me think the SSD is recognized as a HD. I'll attach two pics showing that.
I may be missing something but I can't understand as it was correctly recognized under El Capitan and I've tweaked only a few things after upgrading.
Anyone can help? I looked up on google but I can only find people who can't get their SSD to be recognized at all but no one having a similar problem.
Thank you very much.
BTW, I am using:
Intel Core Duo 2,93 GHz CPU
4 GB 800 MHz RAM
Kingston SSD V300 120GB
and I only have installed
Clover and its basic drivers64 + NTFS
