corresponding to the gaps between characters. This fixes distortion of the cursor due to expanding it across the gaps. Again for character width 9, when the cursor characters are not in the graphics range (0xb0-0xdf), the gaps were always there (filled in the background color for the previous char). They still look strange, but don't cause distortion. When the cursor characters are in the graphics range, the gaps are filled by repeating the previous line. This gives distortion with cilia. Removing vertical lines reduces the distortion to vertical cilia. Move the default for the cursor characters out of the graphics range. With character width 9, this gives gaps instead of distortion and other problems. With character width 8, it just fixes a smaller set of other problems. Some distortion and other problems can be recovered using vidcontrol -M. Presumably the default was to fill the gaps intentionally, but it is much better to leave gaps. The gaps can even be considered as a feature for text processing -- they give sub-pointers to character boundaries. The other problems are: (1) with character width 9, characters near the cursor are moved into the graphics range and thus distorted if any of their 8th bits is set; (2) conflicts with national characters in the graphics range. The default range for the graphics cursor characters is now 8-11. This doesn't conflict with anything, since the glyphs for the characters in this range are unreachable. Use the 10x16 mouse cursor in text mode too (if the font size is >= 14). When the character width is 9, removal of 1 or 2 vertical lines makes 10x16 cursor no wider than the 9x13 one usually was. We could even handle cursors 1 pixel wider in 2 character cells and gaps without more clipping than given by the gaps (the worst case is 1 pixel in the left cell, 1 removed in the middle gap, 8 in the right cell and 1 removed in the right gap. The pixel in the right gap is removed so it doesn't matter if it is in the font). When the character width is 8, we now clip the 10-wide cursor by 1 pixel in the worst case. This clipping is usually invisible since it is of the border and and the border usually merges with the background so is invisible. There should be an option to use reverse video to highlight the border and its tip instead of the interior (graphics mode can do better using separate colors). This needs the 9x13 cursor again. Ideas from: ache (especially about the bad default character range)

The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7) and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables.
The buildkernel and installkernel targets build and install
the kernel and the modules (see below). Please see the top of
the Makefile in this directory for more information on the

Building a kernel is a somewhat more involved process. See build(7), config(8), and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html for more information.
Note: If you want to build and install the kernel with the
buildkernel and installkernel targets, you might need to build
world before. More information is available in the handbook.
The kernel configuration files reside in the sys/<arch>/conf
