Stuck in enabling microcode Intel updates

I am at the step "Install a bootloader" from the Begginers' guide of arch.

I installed system-dboot without problems, I guess.

Now I have to enable microcode updates following https://wiki.archlinux.org/index.php/Mi … de_updates

I have two questions:

1. I have to add  /boot/intel-ucode.img as the first initrd in the bootloader config file. This is in addition to the normal initrd file.

So I want to know where is the "bootloader config file", and where is the "normal initrd file".

2. Since I installed system-dboot, I have to use the initrd option twice in /boot/loader/entries/entry.conf.

However, when I want to edit "entry".conf, there's no files to edit in this directory, so my question is what is the name that I have
to give it to this "entry".conf?

Extra:

I remeber mounted the EFI partition at /mnt/boot.

Re: Stuck in enabling microcode Intel updates

1. 
systemd boot loader configuration files are in /boot/loader/entries/
The 'normal' initrd from inside your Arch Linux system /boot/vmlinuz-linux; but from the point of view of the boot loader it is just /vmlinuz-linux

ewaller@turing/home/ewaller % cat  /boot/loader/entries/arch.conf
title Arch Linux
linux /vmlinuz-linux
initrd /intel-ucode.img
initrd /initramfs-linux.img
options root=/dev/sda6 rw acpi_backlight=native


ewaller@turing/home/ewaller %

2.
You lost me.  What is the output of find /boot

/boot/intel-ucode.img
/boot/EFI
/boot/EFI/systemd/systemd/system-bootx64.efi

Re: Stuck in enabling microcode Intel updates

Wait a minute, creating the arch.conf? If you didn't have it before, how are you booting your system?

Re: Stuck in enabling microcode Intel updates

I haven't rebooted the system. The last time I did I switched from the arch image to the root via arch-root.

Re: Stuck in enabling microcode Intel updates

Ah, no wonder you were confused. You need to start here: https://wiki.archlinux.org/index.php/Systemd-boot before getting into the microcode part.

Re: Stuck in enabling microcode Intel updates

Well, the only thing that differs from your link is that in /boot/EFI/systemd/ I have only systemd-bootx64.efi,
I am missing BOOTX64.EFI, but I suppose this is not necessary (right?)

Also I have created the file /boot/loader/loader.conf as it is suggested in your link.

On rebooting it returns:

Failed to open file: intramfs-linux.img
Trying to load files to higher address
Failed to open file: intramfs-linux.img

Re: Stuck in enabling microcode Intel updates

I think /boot/loader/entries/arch.config should be /boot/loader/entries/arch.conf, but it may not matter.
What are the contents of that file?

Re: Stuck in enabling microcode Intel updates

I copied (created by hand) the arch.config, from another arch machine,  as follows:

title Arch Linux
linux /vmlinuz-linux
initrd /initramfs-linux.img
initrd /intel-ucode.img
options root=/dev/sda2 rw

It boots now, strangely o.o

Re: Stuck in enabling microcode Intel updates

BTW,

These updates must be enabled by adding /boot/intel-ucode.img as the first initrd in the bootloader config file. This is in addition to the normal initrd file. See below for instructions for common bootloaders.

Note it appears the solution was fixing your typo:
It should not be

intramfs-linux.img

but rather

initramfs-linux.img

However, I'm happy you made that error because it was finding your article (by searching for "failed to open file: intramfs-linux.img") that led me to notice that I also made this typo.
Isn't that what actually solved this problem?
