I had a failure last week and have just received a new motherboard to replace the old one. I see that it has a lot of wonderful features for Windows that I don't need, among them UEFI.
Am I going to have trouble running Fedora 21 on it? I guess I need to know that before installing it. The instruction manual is of little help, mainly describes installing it as a Windows 8 system using the included installation disk, none of which I will ever see.

UEFI is fully supported in F21, but....
My experience is you cannot take a drive from one system to another becuase of UEFI.
There are ways you can boot with the liveCD and edit stuff so that it will work, but that takes greater knowledge than I have.

That's not related to the type of firmware. It is sometimes a side effect of the default initramfs on Fedora which is hostonly. The rescue boot option uses a nohostonly initramfs which should boot on most any hardware.
Because the motherboard *has* UEFI may not actually require you to *use* it. Check and see if it has a legacy BIOS mode. If it does, you can use that and keep going. If not, then using UEFI requires (at the least) creation of a UEFI boot partition and changes to the bootloader configuration.

Yes I recall seeing some mention of that on this list. So far it looks like I will have to run the board to see what it is unless there's something in the manual I've missed. I saw no detail about the bios settings. I'll go through it again.
Whatever if there's a way I'll give it a try, it's a low-end board with the AMD cpu soldered in similar to the one I am replacing.
Thanks,
Bob

You may have one like mine, where you hit Esc or some key to get a menu, then you can enter the BIOS, or go to a boot menu, etc...I get the menu, select Boot Menu, then I select which to boot from, etc..and UEFI or legacy is which section I can select from, and either what's installed, or DVD, or whatever.

Yes, I find the boot menu convenient, this computer has several drives with different systems and I just select what I want when I boot it. I'll try it tomorrow and see what I bought, mainly for the price!

OS installations are made BIOS or UEFI at the time of installation. So if you have a bunch of legacy OS's that were installed on a BIOS system, then you'll probably find it much easier to use a "legacy BIOS" or "disable UEFI" (very badly named) option. This enables a compatibility support module to present a faux-BIOS to the legacy OS, and sometimes this presents performance limitations and the only way to find out is to test the system separately with UEFI native and CSM-BIOS booting.
If all kernels are relatively recent (approximately version 3.3 or newer), then it's possible for the Fedora 21 grub2-efi package to support booting all of these legacy OS's in native UEFI mode. The key factor is if the kernel has EFISTUB enabled at the time it was built.
I think GRUB also has a command that allows enabling the CSM-BIOS per boot. So that might be another way around this. But now we're deep in multiboot weeds...
