The Pegatron 2a99 is an OEM (Original Equipment Manufacturer) motherboard found primarily inside HP (Hewlett-Packard) desktop computers, most notably the HP Pavilion p6 series (such as the p6-2375ea) and some Compaq Presario models. Cause: BIOS limitation

It is based on the AMD A75 (Hudson-D2) chipset and was designed for the AMD Trinity/Richland APU era (FM2 socket).

The Verdict: It is a stable, budget-tier board designed for office and home theater PCs. However, because it is an OEM product, finding specific "Pegatron 2a99 drivers" on Pegatron's website is impossible. You must use HP's support portal or AMD’s generic drivers.

Cause: BIOS limitation. The Pegatron 2a99 BIOS does not support UEFI GPUs. Fix: Set BIOS to "Legacy" or "CSM" mode. If your new GPU is UEFI-only (RTX 30 series+), it will not work. Stick to pre-RTX 20 series cards.
