" rel="nofollow - Good morning. I would like to give you a couple of questions.
I just assembled a PC with an Asrock H270M-ITX / ac motherboard and Windows 10 x64 on an M.2 SSD as an operating system. I noticed 2 problems:
1) I immediately installed Asrock's APP SHOP, which has correctly found and installed all the drivers. The app, however, does not detect any BIOS update (I currently have version 1.10), while the site of the card indicates several versions after mine (currently 2.00).
2) I configured 2 HD from 6TB in RAID 1 for backup.
I tried to follow the procedure to configure the RAID in the manual, but I found a problem.
If I go into the BIOS and set "CSM"->"Launch Video OpROM Policy" to "UEFI only" then restart and try to go to "Storage" -> "Intel Rapid Storage Technology" the BIOS freezes and I must forcibly shut down the PC.
Instead, if I completely disable the CSM, I can correctly configure RAID from "Storage" -> "Intel Rapid Storage Technology".
Are these bugs?
Thanks in advance
