Use CPU-Z (free). Go to the "Mainboard" tab. You will see the real brand (e.g., "ASRock," "Gigabyte," "Dell," or "Intel").
Another possibility is a misidentification. Many motherboards display “AMI Aptio” during POST. A user looking at a system built in 2021 with a budget or legacy chipset (like an Intel H61, originally from 2011) might misread a copyright date “2006” (perhaps the start of AMI’s Aptio line) as the board’s design year. In truth, Aptio was introduced around 2011–2012, not 2006. So “2006” could be a red herring — possibly a typo of 2016 or a reference to ACPI or SMBIOS spec versions. ami aptio dt 2006 mainboard 2021

The "AMI Aptio DT 2006" refers to a motherboard reference design from the (circa 2006), utilizing AMI’s early hybrid UEFI firmware (Aptio DT). By 2021, this platform is considered obsolete (over 15 years old). It is incapable of running modern operating systems (Windows 10/11, modern Linux) optimally due to lack of driver support, security mitigations, and performance bottlenecks. Its primary 2021 use case is legacy industrial control , retro gaming , or offline data logging . Another possibility is a misidentification
