Sata drives not enumerated in Bios main storage page, but appear in boot order page

Most of the time, no drives will show, yet the system always boots fine.
The only place they always show is if you select the boot order.

I updated bios, I reset bios, and sometimes when set to IDE, not AHCI, they all appear in the list, but that is also iffy. The last time they appeared was when I reset to default settings.

The board detects the drives, I see a flash page of it seeing the drives as it boots up, it is in the bios page where it normally would display drives connected to sata ports 1-6 that shows a total blank area.

Board is an ASUS-M4A87TD-EVO.

Which BIOS version and OS are you on? Other than the drives being invisible, do you experience any other issues like abnormal temp readings or CPU_Fan warnings?

version 2001 listed here.

I run Linux Mint 18.3
But bios is before all and any type of OS's.

No other issues noticed at all.

The bios I think is buggy.
I reset cmos, then drives appear. Drives are set to IDE, not AHCI.
I set to AHCI, drives disappear!
And if I have 2 drives in the system, sometimes it can not see my primary boot drive, I could not set it to the 1gb drive in the boot order page as it did not appear there.
So I unplugged the 320 gb drive, and on a reboot, it booted the 1gb drive.

It all seems to go to crud when AHCI is selected instead of IDE.
