### Lack of Firmware Update

According to user feedback, this motherboard sees few firmware updates and there are multiple known firmware bugs:

- Early firmware lacked the option to turn off x86 UEFI GOP emulation for GPUs, causing newer AMD graphics cards (RX 5000 and above) and Intel discrete graphics cards to be unusable.
- Some firmware versions do not output a display signal from discrete graphics cards, while the onboard HDMI output (7A2000) only displays a cursor.
