[ale] No RAM = No BIOS?

Based on research I did last night, this makes sense. I was unaware of
it, but evidently the video card is supposed to be initialized before
the system RAM is verified. I suppose that makes sense, so that you
can see the test being performed. I figured the BIOS would at least
verify RAM is available before trying to initialize the video card.

Anyway, if the motherboard has an on-board video card, and that's the
one you are trying to use, then it makes sense that you wouldn't get
video without RAM installed. The on-board video cards do not have any
VRAM what-so-ever since they can just take a chunk of the system RAM.
But if you have no system RAM for that to happen, what is the video
card going to use for storing display data?
