BIOS Update (USB BIOS Flashback):

The ASRock B850i Lightning WiFi 6E supports BIOS Flashback, allowing you to update the BIOS without a CPU, RAM, or graphics card installed. This is particularly useful for ensuring compatibility with newer CPUs. For a visual guide, please refer to the official tutorial video below.

Summary of BIOS Flashback Steps:

1. Prepare a USB drive (FAT32 formatted, at least 32GB).
2. Download the latest BIOS from the ASRock website for your specific model.
3. Extract the BIOS file and rename it to "CREATIVE.ROM".
4. Copy "CREATIVE.ROM" to the root directory of your prepared USB drive.
5. Turn off the system and ensure the power supply's AC switch is off for 3 minutes, then turn it back on (do not power on the system).
6. Insert the USB drive into the designated USB BIOS Flashback port on the rear I/O panel.
7. Press and hold the USB BIOS Flashback button for about 3 seconds until the LED light starts to blink.
8. Wait until the LED stops blinking, indicating the BIOS update is complete.
