I have downloaded the current netinst and
burned it to a DVD.
When I boot it, the first screen I see shows
the usual beginning with choices "Graphics Install,"
"Install," "Advanced".
I choose "Install" and press F10.
The monitor then shows a row of what look like
tiny screen images at the top, with the rest of
the monitor all black. Crtl-Alt-F1, etc makes
changes in the tiny images at the top, but the
all-black rest of screen is unchanged.
At this point, I'm just guessing. I tried
repeating the process, except that I changed
linux /install.amd/vmlinuz vga=788 --- quiet
to
linux /install.amd/vmlinuz vga=normal fb=false --- quiet
and pressing F10. This gave me an all-black screen,
no tiny row.
I really hope somebody can tell me what "magic words"
I should be using. (I tried "nomodeset" but that didn't help)
