yes the kbd leds flash when powered up and they work in 2 other systems.been
there done that.No fuse o the mobo, just a 0 ohm jumper,heck at least on the
first tandy machines they had the 1Amp fuse in an onboard socket.
The PC 'hangs' at the 'cmos checksum error routine....awaiting either f1 or
del key to be pressed. After that is when the BIOS will check for the
floppy, so it sits in 'lala' land.
Many machines have a flash recovery mechanism that does not require the BIOS to initialise the display or even check for peripherals. With the correct jumper set or key held down at power on they will boot off a floppy before initialising the display, re-program the BIOS chip and beep to let you know it's finished, you then reset the jumper to its original position, power cycle the machine and away you go.

Check the manufacturer's website and see if your board will do this.
if you want to see this happen, just pull your battery or clear CMOS and
watch what happens....
I'm well aware of what happens when a PC POSTs, I don't need you to explain this to me.
