Maybe the question is not important: I found written in the Bios Glossary that the GENERAL OPTIMIZATION in the BIOS makes the Raid (0) still being bootable but it can not be configured anymore.
What is meant: Can I not configure anymore or is the software (f. example IRST) unable to?
I do not have to configure these days anything (removing or adding a SSD or something else).
But it is not sure for me what the IRST-Softw. makes - it also configures (not obviously) and works on and on ...for sure in the background or whatever.
