Hi all,
I'm trying to get a new computer working. I've decided to go the UEFI
route but something is being a bit obstinate. Would anyone have the
combination of a Gigabyte motherboard, x470 Ultra, with an AMD Ryzen 7
2700 CPU? Set up to run UEFI?
I'm having all sorts of trouble trying to get things running and if
anyone would happen to have a working kernel config for the above combo,
and is willing to share, it would be greatly appreciated.
Regards,
Andrew

One small thing I noticed doing a Gentoo setup on UEFI ...
The VFAT driver ( in UEFI ) never loaded until Windows was installed on
a drive.
Almost as if the driver was checking for Windows before loading ...
Every attempt to do a Gentoo UEFI install FAILED, because the VFAT
driver would not load.
So ... Windows setup UEFI just fine. Gentoo is using GPT/GRUB.
Every time I boot, the "Boot Menu" gets used to choose the OS.

What do you mean "would not load"? From the live ISO?
I had no such problem here on a bare metal install (no Windows) with
sysrescuecd. You have to make sure the sysrescuecd is booting in UEFI mode
before you proceed with the installation.

I am booting without a boot loader straight from UEFI as this not a multiboot
system. So, unless I interrupt it pressing F2 to get into UEFI menu, it will
boot into the default OS image, which is the latest I have setup with
efibootmgr.

( Clarification ) The UEFI implementation installed on my MB would not
load the VFAT driver.
I did use a Gentoo install ISO to do the setup. The CSM is set to UEFI.
( If I turn off the CSM, it disables both UEFI && Legacy for the Video /
Drive Controller. )
The VFAT partition was unreadable by the MB / UEFI firmware, without the
UEFI VFAT driver loading.

What error messages, indications, behaviour do you get and at what stage?

Well, the Gentoo Live-CD may not be the best image to boot your hardware with.
I'd give systemrescuecd a spin, it has never failed me so far, although a few
years ago I had to perform some tricks to get it to boot into UEFI mode.

If what you are describing re. VFAT driver is a MoBo firmware bug, then I can
only suggest you upgrade to the latest version of OEM BIOS/UEFI firmware and
if that doesn't work you return the MoBo and get another make/model.

Answers to questions :
The VFAT driver in question is built-in to UEFI.
It is not the Linux kernel module you may be thinking of.
UEFI was a long list of built-in drivers.
Old BIOS based systems had a 1 or 2 Megabyte EPROM in use for the BIOS.
UEFI has 32, 64, or 128 Megabyte EPROMs on the motherboard == driver
storage space.
Remember DOS and all those drivers that had to be setup, just to get
basic hardware working?
UEFI is the equivalent of all those drivers being packaged into the
EPROM, with auto-config enabled.
The EFI Shell has a specific command that will "print-to-screen" all
loaded UEFI drivers.
That command was showing only the NTFS filesystem driver loading.
After Windows was installed on a second drive, the UEFI VFAT driver
started loading.
( the Windows Boot Loader had installed itself into the UEFI )
My MB has the latest firmware from the factory.
Linux has to be run with "efi=old_map" appended to the kernel parameters.
( Windows 8.1 UEFI memory map )
I was using the standard Gentoo install ISO, Minimal Installation CD.

Memory is fuzzy ... I think I did try it in UEFI mode.
Next time I will try the systemrescuecd in UEFI mode instead.
