Re: TOS 7 Is Now Out of Beta — Official Release
After upgrading from TOS 6 to TOS 7, I've been prompted to enter my username and password for two hours now. But after I enter the password, nothing happens and I'm prompted to enter it again. It keeps repeating. What am I doing wrong?
I have an F6-424 Max, and I have 3 volumes. The system is on Volume3 (SSD).

Yes, you can upgrade with an M.2 SSD first, then add four HDDs that were used with TOS 6 but don't have a system installed.
After the TOS upgrade, keep the NAS running and plug in the four HDDs while it's on. You can then assemble and mount them through Storage Management, or just run the script /etc/tos/scripts/mntdata in the terminal.
One thing to watch out for:
The old HDDs may still contain old boot partition kernels, which could interfere with TOS 7. To avoid this, after completing the above steps, you may consider migrating the TOS system to each HDD one by one, and finally back to the SSD. This temporary workaround helps prevent potential kernel‑OS mismatches that might otherwise occur.

My updated to 7.0.0777—no problems.
F8 SSD Plus MADN0301. V02 TOS 7.0.0777

I see that the main problem users face when installing TOS 7 is trying to figure out what BIOS version they have, and whether they need to flash the BIOS or change the boot order.
We understand that connecting a NAS to a monitor and keyboard is quite a difficult task, and sometimes impossible in a home environment.
However, there is a mechanism that allows checking and changing the boot order directly from the installation script: efibootmgr.
It is present in TOS 7 (i cannot check regarding TOS 6).
Why not use it in the installation script, or recommend using it from the terminal before installing TOS 7?

I had to "hard" power off the device. After turning it back on, everything worked.nomadfromx wrote: ↑Yesterday, 05:49 After upgrading from TOS 6 to TOS 7, I've been prompted to enter my username and password for two hours now.

Thank you for sharing your concerns. We fully understand that updating the BIOS can feel like an extra burden, especially when you've been using your TerraMaster device smoothly for years.
Over the past decade, TerraMaster has released multiple hardware revisions, and early BIOS implementations did not follow a unified standard. As we developed TOS 7 with a newer kernel, enhanced security features, and improved hardware support, we discovered that some older BIOS versions cannot correctly pass ACPI tables, NVMe initialization parameters, or power management information to the new OS. Without a BIOS update, users could experience system instability, peripheral detection failures, random freezes, or even boot failures.
We do not take this decision lightly. Requiring a BIOS update was a necessary step to ensure every user gets a stable, secure, and fully compatible TOS 7 experience.
To minimize inconvenience, we have already:
Published detailed, step-by-step BIOS update guides with screenshots and checksums for each affected model on our official website.
Opened a remote assistance channel – if you are uncomfortable performing the update yourself, our technical support team can guide you through it remotely.
Standardized BIOS across all newly manufactured hardware, so future major OS upgrades will not require manual BIOS updates again.
We sincerely apologize for the trouble this causes. If you encounter any issues during the process, please contact us directly – we are here to help.
Thank you for your understanding and continued trust in TerraMaster.
