the combo III daughter card on this motherboard can only use 22*60mm M.2 ssd, so I choose the sandisk A110 M.2 SSD (in ASUS's vendor list) as my boot disk. But it seems that the SSD can not work well with the motherboard under UEFI mode. Yes, it do work well under legacy mode, but, when I set the CSM to disable, or set the CSM to enable but leave all the setting in the CSM as UEFI first, the sandisk A110 just disappeared from the boot device list in the UEFI bios.
I wonder if any body use the same SSD? do you encounter the same problem with me? How can I deal with this problem?
