Thanks for the tip.  The duff bios (from February, on my Asus X370-Pro
MB) was exactly what my problem was.  After finding the appropriate page
on the Asus site (which Asus went out of their way to hide) and
downloading and flashing the up to date BIOS, my PC started working.

By working, I mean that I could use both RAM sticks without the BIOS
program hanging, and the Gentoo minimal CD would actually boot.  :-)

Well, I had to prise a "standard" backing plate of the motherboard with
a screwdriver, because some intelligent person had decided to glue it
on.  (By backing plate, I mean the metal plate which supports the weight
of the processor cooler.)

All in all, the MB I bought wasn't of merchantable quality.  I hope it
is, now.

I've got 90% through a Gentoo installation on it, and I'm just
considering how best to un-mdadm my boot partition (which I mistakenly
turned into a RAID partition with its partner on the other drive).  I
can't erase the mdadm metadata stuff with mkfs.ext4 (even with the
"force" parameter), and I don't think mdadm provides a method for
undoing RAID.  I can see myself having to use dd from /dev/zero to be
able to get my partitions back again.

Or can grub2 handle RAID partitions?  This is the first time I've ever
used grub2.

But the installation kernel is 4.9.16.  I've not noticed (yet) anything
failing to work which I would expect to work.  Once I've got my own
kernel up and running, I'll start looking at 4.10.x.
