Asking for Sanity Check before Bootloader Update

[tangofan]

After successfully upgrading from OPNsense 26.1.11_10 to 26.7.1_1, I am looking into running the microcode plugin for my Intel Celeron J6412 CPU again. (I had been running it in the past, but uninstalled it some time ago.)

If I understand things correctly, I should first install a new bootloader, due to a bug in the older version. However since I've never done anything like this, I'd appreciate a sanity check, before I do this. After reading this post and Patrick M. Hausen's response to it right afterwards, I compiled a similar list of system outputs, which hopefully is enough to discern the state of my partitions:

If I understand Patrick's response correctly, all I need to do (since the EFI partition is already mounted and I'm okay with leaving it that way) is to run

Code Select Expand

mkdir -p /boot/efi/efi/boot /boot/efi/efi/freebsd
cp /boot/loader.efi /boot/efi/efi/boot/bootx64.efi
cp /boot/loader.efi /boot/efi/efi/freebsd/loader.efi

to update the EFI bootloader (though the first line is actually superfluous in my case, since the directories already exist) and then run

Code Select Expand

gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 2 ada0
to update the BIOS bootloader (with "nda0" in the original post changed to "ada0" for my setup).

Am I understanding things correctly? Thanks so much in advance for any help and advice with this.

You only need this if you want to be prepared in case you ever transfer your drive with the complete installation on it to an older system that still uses legacy boot instead of UEFI. If that is not a scenario you deem worth considering, you can ignore the legacy boot partition entirely.

HTH,
Patrick

Patrick, thanks a bunch for the quick response and the confirmation. I'll implement this at the next "family-approved maintenance window" for the router.

Updating the BIOS bootloader sounds like something that doesn't have any downside and is easy to do, so I might as well do it, though I likely will never need it.

[Patrick M. Hausen]

It won't cause any downtime. You do not strictly need to reboot the system, you know?

[tangofan]

Not strictly perhaps, but then I might as well test the change right away and make sure the system comes back up. Otherwise, if the system fails to boot at a later time - say after the next OPNsense update/upgrade - I'm dealing with multiple potential root causes. So I'd rather keep it simple and straightforward.

But he needs to know if the microcode stuff will boot and work correctly ?!

So this :

Is then the way to go IMHO ?!

Exactly how would he check the microcode stuff is loaded and functioning ?

The bootloader update went without a hitch and so did the install of the os-cpu-microcode-intel plugin and subsequent reboot. However I couldn't find anything in the dmesg output that would point to the plugin doing something:

FWIW I ran the command

Code Select Expand

x86info -a | grep -i micro and it told me that the microcode version of my Intel Celeron J6412 CPU is 0x000000000000001a. Unfortunately x86info uninstalls, when I uninstall the plugin, so I couldn't check the microcode version without it installed.

So does this mean that there is a problem with the plugin? If so, how can I trace down the root cause?

The second instance of the CPU identification lines starting with "CPU: Intel(R) Celeron(R) J6412 @ 2.00GHz (1996.80-MHz K8-class CPU)" shows that the plugin ran. If there is an update for your CPU model, it was applied.
