Here Asus Rampage II Extreme is mentioned working fine with LSI 9260-8i.
Indeed, it works, but I cannot enter controller bios. No way. Pressing key combination during boot results in nothing, the board continues booting Windows. I haven't seen Webbios since purchase of the controller. LOL I know how Webbios looks like only from screenshots in Internet)) I had to make all raid setup in Windows with Megaraid SM.
Setup tested:
Asus RIIE bios 1639, 1704, 1802 (latest)
9260-8i firmware 12.0.1-0081_SAS_FW_Image_2.0.03-0725, 12.3.0-0022_SAS_FW_Image_APP-2.30.03-0775 (latest)
Does anyone have the same problem?
