This decade being the 2010s? :-)

It's true that really old PCs couldn't boot without a keyboard which
lead to the joke
  "Keyboard missing.  Press F1 to continue"

However the change to the hardware to allow a keyboardless boot came in
a lot longer than a decade ago.  It might have been with the 386 based
hardware, but I really can't remember.  I know I had a PC built in the
90s which has a BIOS option to halt on all errors, or halt on all errors
except keyboard.

Here's a PDF from 1998 showing the option

I'm sure sufficient googling would find even older examples.

Of course modern PCs may not even _have_ a keyboard port; USB only!
