Sean:

 According to the description, I agree with Pedro that this is a recommendation and not mandatory. Do you think so?

 

Thanks

Hi Sean,

 

I think it's clear from the wording that the 38.2% thing is a recommendation and not mandatory. I was curious and checked out the ACPI spec and they appear to not mention that at all. Maybe reword things to "Microsoft recommendation"?

 

Thanks,

Pedro

Microsoft details about positioning can be found here: https://docs.microsoft.com/en-us/windows-hardware/drivers/bringup/boot-screen-components

 

Thanks
