Gamers are welcome to visit the download area on the AYANEO official website to obtain the "AYANEO KUN BIOS & Audio Driver."

BIOS Function Description:

• Fixed some performance issues in D3D11 games.
• Added the option to switch between memory frequencies of 7500MHz and 6400MHz in the BIOS interface.
• Fixed the issue of no sound caused by flashing the old 7500 BIOS.

Instructions for Use:

• Update the BIOS first.
• After updating the BIOS, there may be a chance of the sound card failing from different batches, resulting in no sound.
• If there is no sound, you need to install the audio driver separately. The audio driver version is: 2023/8/29 6.0.9570.1
• After installing the audio driver, restart the device for the changes to take effect.

BIOS Installation Method:

• First, plug in the device and charge it.
• Do not run the script file in a path with Chinese characters, as it will fail to run.
• Right-click and run the [01-start.bat] file as an administrator.
• The device will update the BIOS (no operation is required during this period, and it will shut down automatically after flashing is complete).
• After the device shuts down, wait for more than 3 minutes, then press the power button to turn it on (the first boot time may be longer after flashing, but gamers don't need to worry).
• The flashing process is complete once you enter the Windows interface.

Audio Driver Installation Method:

• Open the folder 9570.1_UAD_WHQL_2023_0907.
