Details:

I am having an issue with a boot-time GNU GRUB configuration bug.
Although I have configured the boot menu timout, the boot menu only flashes on
screen briefly for 3/100ths of a second and disappears. I have tried all sorts
of combinations of configuration changes and just cannot seem to do anything
to get the boot menu to actually stay on the screen.

Examples of the settings that I have tried in /etc/default/grub:

GRUB_TIMEOUT=5

GRUB_TIMEOUT=5000

GRUB_TIMEOUT=-1

I have used a burst frame camera to take a picture of the screen that displays
and to time how long it is present. Here is the boot menu that displays for
3/100ths of a second (when GRUB_TIMEOUT=5):

Note that when GRUB_TIMEOUT=5, the screen says, "The highlighted entry will be
executed automatically in 5s," but it immediately disappears after only
3/100ths of a second.

I have also tried holding down keys immediately after entering the BIOS boot
password.
I tried holding down: down-arrow, Esc, left-shift, and right-shift. Nothing
made the boot menu linger.
I also tried a few times booting while pressing the down-arrow as fast as I
could. Still the boot menu just flashed by.

The GRUB version is 2.02 installed on an MSI Wind U100 netbook running
up-to-date archlinux32.

Attached are the /etc/default/grub and generated /boot/grub/grub.cfg files on
my system.
