Thank you for contacting the Intel community.
In this case, this can be a limitation from your computer manufacturer, updating the IRST will not show you the acceleration option, in order for you to have this option available you will need to set the BIOS to RAID mode and install the operating system in this mode.
If you need more assistance related to your BIOS and compatibility with your system your best contact support is with your computer manufacturer as they are more familiar with your system than we are.
Ups! I think you may be right. I dont have the raid option in my bios and my bios is updated to the last build.
Bad luck then, my computer comes with internal 8gb ssd but I cant use it... weird.
Thank you for your time.
