Sounds very strange - having ruled out keyboard malfunction, power issues, and the fact it works if booting to the OS, on two separate boards, there is not much left...
The BIOS, if it can't find an OS to load, will show a UEFI shell prompt. It won't tell you the version, but at least it confirms the BIOS is happy.
Also, if the BIOS is up in the shell prompt, it will enumerate a USB keyboard if you plug it in at that point. Or if you switch ports for the keyboard.
Is the OS you run installed on that board, or from a reference board?
Is it running from the micro SD card, a USB Flash drive, a SATA disk, or something plugged into the high speed interface on a lure?
Thanks,

Well... I finally got the quad (with the 4amp power supply) to work with the "reboot from a running Linux" trick.
At least for that board, the BIOS menu says the following:
Minnowboard Turbot D0 PLATFORM
Intel(R) Atom(TM) CPU E3845 @1.91 Ghz
MNW2MAX1.X64.0095.R01.1703281124
Which, I presume, means that the BIOS is Rev 0095.R01 compiled at 11:24 AM on March 28, 2017. So I'm two revs behind the leading edge.
The dual (with the 2amp power supply) is still refusing to yield its secrets.
Sometime this weekend, I hope to have time to reflash the BIOS with Rev 0097 as mentioned in Brian's post.
