BIOS Version MADNO102.V05

Error message after login to TOS 7.0 as follows:

"It has been detected that the bios boot order of your TNAS device does not match the default factory settings. This anomaly will affect the normal operation of storage services and other system functions.

Solution:
1) Shut down the TNAS device
2) Restart and enter bios setup interface
3) Locate the "TOS BOOT FIRST" option and set it to enabled
4) Save the changes and exit the bios.

After completing the setup, restarting the TNAS device will restore normal operation."


I can verify that the TOS BOOT FIRST option is enabled. Message still persists. This update has essentially bricked my TNAS device making it unusable. I am grateful for any suggestion that can overcome this problem Thank you in advance.

The TOS appears to boot normally, because I can login to the web interface.. however this warning doesn't not allow me to pass with only the option to shutdown the device.

I forgot to mention that my device is TNAS F6-424.
