Sorry if this is a dumb question but how are you able to configure/install UnRaid if you can't see the BIOS screen? If you have the install medium on a USB stick plugged into the NAS, won't it just ignore the USB stick and boot from QNAP's proprietary software that comes in the box? Even if you remove the DOM with the QNAP software, how can you do the rest of the setup without a display? If the system uses the USB as it's boot disk permanently, aren't there concerns with using a USB flash drive non-stop for many months (like durability or heat or whatnot)?
I tried plugging in a USB-C to HDMI adapter but it's an AMD chip without integrated graphics so I don't know why I thought that would work.
I guess I could temporarily install a GPU in the PCIe slot while I do the install but you all seem to have done something else.
