The solution was on the BIOS setting. Using the option: Analog (VGA)
shows the boot messages on the external monitor and on the laptop lcd.
Also without the external monitor attached, the boot messages show on
the laptop lcd when the Analog options is selected. I added the KMS
option i915.modeset=1 as a grub boot option but don't know if this helps
or not.
