Change the Blue Screen Font hardcoded into bootvid.dll to the Open Source "Anonymous Pro" font, which makes a nice 8x13 font. Blue Screens now look like this: http://fs5.directupload.net/images/160106/ehv6245t.png [BOOTVID_FONT_GENERATOR] In case you find an even better font, you now have a nice little tool to test that font and generate the corresponding FontData array for bootvid. svn path=/trunk/; revision=70507
