[Request] NVMe mod for ASRock Z68 Extreme4 (not Gen3)

Hello.

I read thread about NVMe mod for AMI BIOS. But I’m not sure to mod it. I use ASRock Z68 Extreme4 (not Gen3). I saw mod BIOS for Gen3, not my motherboard. Thank you.

OEM v2.20

OEM L2.21A

Method is here: [HowTo] Get full NVMe support for all Systems with an AMI UEFI BIOS

This is the Z68 Extreme4 L2.21A with updated mCode cpu and NVMe module added, not responsible for any failure to system, flash it at ur own risk using Instant Flash, or do the mod urself.
Insure that the system is updated with the original L2.21A, defaults loaded, prior to the mod flash.

Thank you so much.
