Speaking of ports, especially legacy ports, i'm glad mobo makers still use the old PS2 ports on many motherboards -- that Gigabyte Z97X SLI I built and another Z97 HD3 I build would just not boot up allowing me into the bios with any of my USB keyboards even with the legacy USB 2.0 ports and I noticed similar complaints on newegg, so I was glad to have a few older keyboards around because even a USB~PS2 adaptor initially did not allow any of my USB keyboards to post to the bios. Once drivers were loaded within the OS environment it would then accept a USB keyboard though.
