TerraMaster Official Forum

Hi All,

I'm posting here since support told me that they don't have the latest BIOS for Terramaster NAS model F2-221.

I always have a CMOS checksum error while booting and I would like to update my BIOS with the latest available.

I was looking in the forum but i couldn't find a link for download.

My system is
S/N S-TM-J33AKG-201300447
BIOS:
AMERICAN MEGATRENDS
VERSION 2.18.1263
TM-J33A VER:G1.0G (2018/12/17)

thanks in advance.

If you're getting CMOS checksum error on every restart, you should probably check the voltage of the RTC battery as it likely requires replacement.

As far as UEFI updates, there hasn't been a thread regarding the ×21 series; there have been updates for the ×23 series @ viewtopic.php?f=82&t=4238; only the bootloader is available for download for the ×21 series @ https://dl.terra-master.com/cn/PATCH/co ... 5.1.47.img, however the USB initboot should automatically attempt to grab this update upon initialization of a TNAS that has Internet connectivity.
