HP z420, WIN 10 64 bit installed. I upgraded this system with 2 non-ssd drives and 2 ssd drives, enabled RAID on the system, then decided I didn't need it. I turned off everything I remember turning on but here's my symptoms:
-Intel Rapid Storage Technology enterprise - SATA Option ROM still pops up at boot
-American Megatrends (ctrl + P to enter MEBX setup menu) still pops up at boot
-Any drive not plugged into the white SATA ports on the board doesn't get recognized
-SSDs plugged into the two grey ports are recognized
What happened here and I can get additional drives recognized?

Attempted to update the storage drivers, message popped stating the version installed on the machine was higher than the version being installed. I installed anyways, this fixed it.

Further information, when I just have two SSDs plugged in the machine does boot up to the OS and appear to function correctly.
Also, I've switched out HDs, sata cables, changed what SATA power ports I'm using. I've also checked integrity of every HD I'm using, they're all good.

In attempting to flush RAID completely out of my system I consulted this page: https://support.hp.com/si-en/document/c01720221
As I stated before AHCI + RAID vs AHCI setting has no effect. Once I get into the Intel Storage Manger I don't have any RAID volumes to delete, but it does see the two hard drives my actual machine does not. Also, following the instructions, I didn't have a " SATA RAID Option ROM Download" as you can see from my BIOS setting screenshots.
