[Beowulf] Problems with Microway Navion/SuperMicro server VGA display

Actually, I take that back. Only partially user error.  My Tesla's do
have an DVI output, but I was trying to connect to the VGA output.

At first, I thought I was just being stupid (see the last e-mail), then
I remembered something, that may have partially redeemed me: Due to the
location of the DVI input on the Tesla card, the chassis itself
interferes with the DVI connector, so it's impossible to connect the DVI
 cable to the Tesla's DVI output. Not without customizing the chassis
with a Sawzall or Dremel too, at least.

The fix is simple: configure the BIOS to always default to the onboard
VGA. Unfortunately, it's not obvious what the correct selection is.
Here's the section of the manual on this, in it's entirety:

Primary Video Controller

Use this setting to specify the primary video controller boot order.
Options include PCIE-GPP1-GPP2-GPP3a-PCI, PCIE-GPP2-GPP1-GPP3a-PCI,

that make it pretty clear, doesn't it?
