990FX Extreme6 CSM problem

Version of LSI Firmware and BIOS : Firmware 2114ir.bin Version no: 20.00.07.00 Release date: 11-FEB-16 BIOS mptsas2.rom Version no: 7.39.02.00 Release date: 03-AUG-15 Running Windows 7 Pro x64 and  Gentoo Linux x86_64 on separate drives. With CSM "enabled" and Storage opROM set to Legacy ... The LSI Config does launch ... then hard locks the system in the first screen. Tried going the UEFI route per FAQ ( Q&A-97 | 319 ). That resulted in NO controller/No drives showing in the UEFI. System will NOT boot in that configuration. Last I checked, Windows 7 doesn't support UEFI. Win 7 won't boot without CSM "enabled". How do I get the LSI Config Utility, on-board the LSI card, to work?

Not sure what you mean by going the UEFI route? Are you referring to this FAQ file:

You can only set CSM to Disabled if Windows was installed for UEFI booting. That is, with CSM Disabled during the Windows installation.

Windows 7 can support UEFI booting, but the Win 7 installation folder/file layout has a bug that prevents it from working. It can be fixed, but you would need to install Win 7 again with the file layout fix, and set CSM to Disabled. So Win 7 as is does not support UEFI booting. I've used the fix for Win 7 and it worked.

This link contains a guide to do that: http://www.eightforums.com/tutorials/15458-uefi-bootable-usb-flash-drive-create-windows.html

I don't think you need to install Win 7 in UEFI mode to get your LSI card working. Don't know why you think you do. I could be wrong.

I hope you are using AHCI mode for the AMD SATA controller, even if you are not using it. That will help with the following.

Try setting the Storage OpROM policy option to UEFI Only, with CSM Enabled. Well... that might fail as well. I'm not sure what will work for you here.

I'm wondering if the UEFI/BIOS chip of 32MB in your board can deal with the LSI Option ROM? That's on the small side.
