Title: CPU Microcode and Bootloader
Post by: Aveamantium on August 04, 2026, 12:18:01 AM
Been using OPNSense for awhile now and wanted to extend my thanks for all the hard work! 

This whole microcode issue has me a bit confused so I was wondering if the "late load" feature was/will be implemented so you don't need to update the bootloader?  On that note, seems like an up to date bootloader might resolve other issues that have cropped up here/there in these forums.  Would there be a way to include this as an option with future updates or is it more complicated than that?

No worries either way, just more of a curiosity...  Again, thank you for the awesome firewall!

OPNsense 26.7 uses early loading and will hang at boot if you have an outdated boot loader.
OPNsense 26.7.1 uses late loading and will work regardless of the boot loader version.

Anyway it is always advisable to keep your boot loader up to date just like the rest of the system.

Thanks Patrick and appreciate the info...! 

On the boot loader, I was just hoping that at some point it became an option to update within the GUI.  Not that I'm opposed to using the shell...

Thanks Again!
