Subject: Added 'bootdelay' feature in boot monitor, it pauses a given number of ms
X-Git-Tag: v3.1.0~802
X-Git-Url: http://zhaoyanbai.com/repos/Bv9ARM.ch04.html?a=commitdiff_plain;h=5927788cdd66a79a56ca1a3dfdfc063ef59c0698;p=minix.git

Added 'bootdelay' feature in boot monitor, it pauses a given number of ms
so the list of programs in the image and their sizes can be seen before the
kernel starts filling the screen.

Added some formatting fixes in installboot and boot monitor itself,
some of the segments were larger than the formatting allowed.
