It did not make a difference.

That didn't work either. Hitting the button immediately shut down the
machine.

I found another one's hint in the user forums and following it, I was
now able to boot up Haiku - in less than eight seconds: impressive.
What I did was disable hispeed legacy USB in the BIOS settings. You can
toggle between "high speed" and "full speed" in the BIOS. I think this
means EHCI isn't initialized by the BIOS, and booting off USB would be
slow (USB 1.0 probably), but that doesn't hurt me.
