Windows 10: In the "Beginning" There was the "Legacy" ASUS BIOS so what happened to?

I used to be able to see all the SATA information concerning the devices connected via several controller cards attached to various PCIe slots on my ASUS Deluxe Dual MB. I was advised to burn up to the latest FW version and the user attached SATA information seems to have gone Poof. Obviously, my win 10 OS knows as Disk Manager shows all. Is there someone that can reveal the secret of the new Button Presses so I can properly configure the connected devices?

bios

Hi all i am new in this forum, i need meanings step by step of each item listed in the bios Phoenix-Award

 

Need a Legacy Bios R9 270x

Much safer to just modify the original BIOS. The way I suggested is the easiest most efficient way possible to accomplish what you're after. Not trying to toot my own horn...but I'm an ATI/AMD BIOS modding/flashing expert. I've done it literally hundreds, if not thousands, of times.

And yes, they are listed as UEFI Supported(Yes or No).

 

Return to Legacy from UEFI - BIOS

Hi There

A while ago I was helped here to change from Legacy to UEFI. However, since then it seems, the Laptop (Latutide E6420) is running a bit slowly which was otherwise very quick until then. Now, it takes nearly a minute or so to boot up or shut down or even
to close a file. Just a couple of days ago, I updated the latest BIOS for this machine recommended by Dell.

I tried to go back to Legacy but the system was asking me to reset to UEFI or face boot problems. One advise said that I could disable 'Secure Boot' in Boot Manager and reset to Legacy. However, the Boot Manager is listed under UEFI Boot process and it only
starts Windows. Is there any way as easy as I changed it? This is absolutely under the hope that all will be as normal as it was in the beginning. Please give your thoughts and advice. Thanks.
