Thanks

The DS1511+ has a monitor port

Yes, that's unusual. Is the BIOS configured correctly to display anything on the screen? EFI...etc...
Have you tried all the function keys to access the BIOS, if it's still working? F1, F2, F6, ESC, DEL

 

[Nilfe]

But I still don't understand why I can't enter the BIOS and I have a black screen.

How do you connect to that port?

Is there a way to test the BIOS chip with a multimeter?

You are able to install an alternate Loader on the DoM, which size is it?

The device has a VGA port, I connect a monitor and a USB keyboard and restart, DEL or F1, but it doesn't work. Black screen

Just try something different, don't overthink it ;-)
Plug another USB device into a port on the back and try again.

And I tried that, it doesn't load

I just remembered my DS710+; there must be a different device connected to it.

To flash a BIOS, the machine needs to be powered on first, right? Otherwise, you'll need a programming adapter.

Why not just throw it away and get a PC/laptop with a more modern DSM?

Isn’t there a uart jumper on the board as well, so you can establish a serial connection and terminal access?

Flashing can be done with power off using eg. a ch341a programmer and an soic8 clip…

That's exactly what I meant.

I received a higher-quality NAS today for €80. It's a Thecus N2810. Getting something like that for a small amount of money is absolutely no problem. Running DSM 7.3.2u3 with it

Do you get a beep tone, or does the DS1511+ not have that feature?
