Hi,
I have a DELL T110 and like to have a better understanding as to what these settings mean.
There are 4 different mode SATA settings - OFF / ATA Mode / ACHI Mode / RAID Mode. There are two Boot Modes - UEFI (whatever it is) and BIOS. When I choose BIOS mode, and select Boot Sequence, I can see CD/DVD ROM Drive &HD and change priority between them. However if I choose UEFI, the system does not even let me get into boot priority screen.
I like to understand what these 4 SATA settings mean and difference between UEFI and BIOS boot modes.
Thank you.
IF you want to use the hardware RAID (No, it is absolute crap, use host-based software RAID) then turn RAID on.
Otherwise set it to AHCI mode. This basically means I am running a modern operating system and I want the drivers to take advantage of all of the bells and whistles found in modern disk drives, like queuing and support for ATA commands that do I/Os in larger chunks.
There is a lot more to it than that, but bottom line you don't want the other settings unless you want to run MS-DOS on the machine, for example.
