Before we talk about drivers, let’s demystify the hardware.

Pegatron Corporation is a Taiwanese electronics manufacturing company. It spun off from ASUS in 2008. While ASUS focuses on retail motherboards (Prime, ROG, TUF), Pegatron focuses on contract manufacturing. They build boards for HP, Dell, Lenovo, and Apple.

The 2A99 is the model number (often called the "board number" or "product name") assigned to this specific motherboard. In HP’s internal database, it is sometimes referred to using a spare part number like 661279-001 or 661280-001.

Many Pegatron 2A99 systems came with Windows Vista or Windows 7. If you upgraded to Windows 10 or 11, HP may not provide official drivers.
