See Making TrueType bitmap fonts -- but please note the "last updated" date ...
Bitmap-only fonts are really a technology of the past, and FON files even more so. The Windows 7 command line console must be the very last software to actively need it!
My home system, Mac OS X, allows any installed font to be used for its Terminal. And it has more advantages -- for example, Terminal also supports ANSI coloring, XTerm style. The same program on Windows 7 shows lots of useless uninterpreted escape codes, since I have no idea how to install ol' ANSI.SYS on Win 7.
