Uefi/csm -

[Bob Goodwin]

I ordered another Asrock motherboard to replace the one I haven;t been 
able to install Fedora 27 on. The user manual says it can be setup to 
boot uefi or legacy bios by enabling csm. I do not need to dual boot 
with Windows, only Fedora 27 so it appears to me that the legacy option 
is best in my case.

Is that rightor am I missing something?

My understanding is that secure boot is to protect from unauthorized
access to the machine, and prevent unauthorized software from running
on the machine.  Important for things like laptops that are liable to
be stolen, but less necessary for home desktop computers.

That is, I agree with you.  But I look forward to seeing the reasoning
of people who disagree.

Hello.

SecureBoot should not be a problem, because the Bootloader on Fedora is
signed.

I have Secureboot enabled on my machine, which is a HP (Compaq)
Notebook and everything runs fine.

Regards,
Dirk

You are missing something.  Regardless of whether you want to dual boot 
with Windows or not, EFI is a much better boot system.  Also, the GPT 
partition format is a much better system.  And despite the common 
misinformation, secure boot is not required to be on to use EFI boot. 
However, unless you are compiling kernel modules, secure boot being on 
will not be noticeable.

Fedora is supposed to help us work out bugs before they land in Enterprise
distros.  The more Fedora
users give UEFI a try, the better it will work for linux in 2020.

It may be better to experiment with UEFI while you can still get hardware
with BIOS than wait for 2020 to start
figuring out EUFI.

Dell has a white paper  <en.community.dell.com/techcenter/extras/m/
white_papers/20444677/download>.

This document is aimed more at data centers, but it is interesting to read
the section on memory
limits for storage devices and Dell's use of UEFI for NVMe devices.
