[haiku-development] [PATCH] Remove text cursor from bootloader menu screens

This proposed patch turns off the cursor when the video mode is set to text
mode in the bootloader.
This will remove the text cursor in the top-left corner of the screen when
using the bootloader menus.
I also changed a couple of the register assignments to make them clearer.
(They confused me initially)
