We are using X12DPI-NT6 for our systems build and using LSI 9580-8i8e RAID controller in slot2 which normally suppresses the controller BIOS banner and prevents it from appearing as a boot option during POST. However, on this system, the banner still appears despite EFI mode being enabled. We are using Dual boot mode in boot sequence, the video Option ROM is set to Legacy. Is this a known issue?
Please update to BIOS 2.4 that fixed the issue.
