CW-NAS-ADLN-K question: How do I perform a BIOS update correctly?

The international version of the wiki will require some additional time before completion. Currently, if you need further documentation, we recommend either contacting your sales representative directly or requesting materials from us.

1. Since I don't know which version of the BIOS firmware you obtained, please note that since 2025, the new BIOS versions I've released support BIOS updates regardless of the number of hard drives installed. We've added more robust scripts to facilitate this. If you downloaded an older BIOS version, you might need some basic EFI command-line operations to complete the update. Please provide the BIOS firmware filename or download link for clarification.

2. For firmware updates, any USB drive that can be inserted and recognized in the BIOS boot menu can be used.

3. BIOS firmware updates generally take less than 10 minutes to complete.

4. We kindly ask you to provide the BIOS firmware filename or download address you received.

**Note:** If your motherboard is currently operating normally without any issues, we generally do not recommend updating the BIOS. Installing an incorrect BIOS version may result in failure to boot. During the BIOS update process, do not forcibly power off or allow unexpected power loss, as this could also prevent the system from booting again. It is highly recommended to have a BIOS programmer (such as CH341A) available, as every BIOS update carries some risk.

If you continue to experience unresolved issues, please leave another message, and I will continue to follow up.

Thank you very much for the detailed answers. The information you requested here — my current BIOS firmware:

My sales representative sent me the version linked above (download link). It's the one shown in the screenshots:

As I wrote, I had found an even newer BIOS (download link) in your wiki, see screenshots:

I would like to improve my power management, which is offered with the new versions. And the version from the wiki promises the Beep option, with which I can hopefully deactivate the sounds.

Is this, from the wiki, a release version, or a beta or test version?

Thank you very much for your valuable support

Thanks again, I updated the bios without any problems
