I have a 4 bay TS-453 Pro (Celeron J1900). I swapped out one of the HHDs for an SSD with the distro install and created a ZFS array with other three drives. In my experience, BIOS/EFI comes up if you mash F2 with a HDMI monitor and a USB keyboard and mouse attached. Your mileage may vary. A few niggly bits: the LCD says “System Starting” until LCDd/lcdmon starts and there is no control over the HDD activity lights. Fan Control is sufficient to quiet the fans to a tolerable level once Smart Fan is disabled in the EFI. Perhaps I should document this somewhere …
