6 series boards were AMI BIOS (legacy), but could be upgraded to UEFI. Unfortunately it was not a very good implementation of UEFI. 7 series boards have UEFI and you can set your boot mode in the BIOS/UEFI to Legacy Only, UEFI and Legacy and UEFI only. 8 and 9 series boards are UEFI, but with the CSM enabled you can boot legacy mode. 170/150 series boards are UEFI and no sense in trying to install Legacy mode and no need for it..
If installing Yosemite or earlier you can use Legacy mode and Chimera or Clover as boot loader.
For El Capitan or later you can use Clover only and install it Legacy or UEFI depending on your hardware.
Okay, I have a 170 series board and going to use El Capitan.... so, I'll use UEFI.
Thank you
