Hello, I've been researching this for a while and still haven't come to a conclusion. I need some help. I am using asus tinkerboard 2s and now there is TinkerOS 2.0.14 in emmc. 1 hdd with a sata to usb cable and an SSD with a sata to type-c cable are connected to the device. My aim is to boot tinkerboard 2s over ssd with proxmox installed, but I could not do it. Is there no built-in BIOS or BOOT menu in the device? If so, how can I enter? There is very little information on the internet about this.
