This turns out not to be the case.
CSM is a fake BIOS. It is used to implement things link BIOS service calls. These are used by:
- MBR boot loaders (lilo, grub-for-MBR)
- old OSes (like DOS)
- initialization code that might be present in som plug-in cards. This initialization code was considered an extension of the BIOS initialization code. I imagine that these cards are all obsolete now.
My comment left out the last case.
I definitely am trying to get UEFI to boot, not MBR, and while *NIX is an old OS in some sense it isn't the sense that matters here. So, I'll turn off CSM.
