I have also the problem that my brand new Gigabyte GA z97x ud5 bk motherboard does not alway recognises the Intel 530 m.2 180gb ssd in the bios.
At this moment I cannot use the Intel 530 m.2, since I do not have a reliable Windows Operating system.
I hope that both Intel and Gigabyte are able to provide a solution for this problem.
Your Asrock bios update seems to have done the trick, could you ask Asrock what they have done in the bios to ensure the Intel 530 is now correctly
wording each and everytime. (DANKE)
