How to update an outdated TOS4 system?

[cocoykira]

Hi, according to the BIOS information you provided, your F2-221 is from a very old batch (2018). There are no available BIOS updates for it, and it does not support TOS6.

Well, its a pity but Im fine as im not exposing the NAS to internet.
Thanks for the help, just updated it to latest 5 and changed from raid 1 to raid 0 ext4
Cheers!
