ACPI BIOS Error - Help to Make Sense of This

Hello,

May I please request assistance understanding what the below messages mean? I understand that I can safely ignore them; and Zorin boots up just fine when ignored.
However, I would be very appreciative if someone out there possesses experience with this sort of thing; and wouldn't mind taking some time to teach other Zorin users about what this means for their system.

I would also like to note that while the bug/warning messages can be ignored, I still would like to find a way to clear these myself if possible, with some guidance which I'm not able to locate in my internet searches

One thing I've tried is to go into BIOS SATA settings to change configuration to ACPI. My BIOS does not have this option.

I've also found some possible info related to drive encryption/decryption swap/turnover upon reboot, but not sure about how that would apply to my specific error. I don't want to derail this at all either... so with a grain of salt.

No change using Advanced options menu in OS select for alternative kernel.

This has been happening since install and re-install of Zorin for a good, long while - an action taken due to unrelated issues.

Below are each of the errors I see after Grub menu selection. Please note that I had to pick and choose each error/message, but this is the full list prior to OS load.

Let me know if you want my neofetch or other sysinfo to facilitate resolution for this request.

Thank you for taking the time.

These are your ACPI Tables:

On your OS - whether Zorin OS or Windows OS - The motherboard operating System (BIOS) must reference the ACPI tables.
If there is a mismatch between the BIOS and the tables, either due to a necessary upgrade in your BIOS firmware or due to a flaw in the ACPI tables you are using, then it will throw those errors.
These generally deal with PCI root bridge enumeration data and they may affect Power Management. Power Management is the only one that you may notice an effect on - usually if you are using a Notebook computer.
So, while it can be annoying; they are generally not harmful to the system.

You can usually quiet it, if you want, by modifying grub to only relay important errors, instead of all errors no matter how minor:

sudo nano /etc/default/grub

Change line to read as
GRUB_CMDLINE_LINUX_DEFAULT='quiet splash loglevel=3'
Tap ctrl+x, then y, then enter
Run

sudo update-grub

Just to add this is down to Microsoft not implementing ACPI standards, leading to manufacturers of machines having differing ACPI standards from what should be.
