Understand UEFI and CSM BIOS setting for ASUS H97-Plus
I don't know if anyone has tried to contact ASUS support but impossible. FWIW sorry I went with this ASUS board but from reading ASUS now makes about 80 percent of all boards. Hope we can get some competition from the good ole USA and show them how its done.
In discussion with American Megatrends today, found out they sell their base BIOS to MOBO manufacturers and then the BIOS manufacturers modify it to their liking. IMHO, who modified this BIOS for ASUS must of had a nightmare the night before.
I found two numbers for this BIOS.
I "think" they relate to each company as follows:
-- ASUS ver 2202
-- American Megatrends ver. 2.16.1240
=========== My Questons ===================
1) If someone has this board and BIOS can they explain to me when I should set the CSM for UEFI when running Windows 7?
2) My BIOS shows Boot Secure Enabled but I can't figure out how to turn it off and this "Secure Boot" choice cannot be toggled.
Is their some setting elsewhere I need to set in order to toggle "Secure Boot"?
3) Under PCH Storage Configuation they indicate this item will automatically detect between M.2 devices and SATA devices. What are M.2 devices?
4) Under SATA Mode Selection (AHCI)
this has a setting of IDE, AHCI, and RAID. With a SATA boot drive and setting to IDE, Windows 7 will Not load. I iniitally thought that if I had a non-boot IDE drive attached that needed to be set for it (the IDE), obviously Not. Any clarification here would be helpful.
5) Regarding boot device configuration can someone confirm if my interpretation is correct.
-- UEFI and Legacy OpROM.
My guess is UEFI is the "Bios" renamed and is now called UEFI and that the OpROM (whatever that stands for) is the older traditional BIOS prior to UEFI. If I'm correct and this is UEFI "biod"why would you set OpROM in thie Bios itself? Help needed here.
-- Boot from Network Devices. How do you boot from a Network device?
-- Boot from Storage Devices. Again what do they mean by a Storage device and how does one boot from it?
-- Boot from PCIe/PCI Expansion Device. My guess here is if you have a daughter board with an IDE that installed in a PCIe or PCI slot, that one can boot from the IDE drive connected to this daughter board.
Confused and enough for now.
