E. C. Masloch 3415ad93c9 boot32: fix very old bug, init high byte of fat_secshift 
It turned out that this loader was severely broken for many years,
at least since 2012 (the git repo's creation). This variable was
read as a word to set cx for a loop, but only the low byte had
been written. The high byte happened to be 0EEh so cn_loop would
always zero out the FAT sector to read.

This _happened_ to work if the first root directory cluster and
all the kernel file clusters were all referenced in the first
sector of the FAT. Otherwise it would blow up.

fd kernel

FreeDOS kernel - current 0xFD version is 2.43 (2043)

http://www.fdos.org/kernel/

The FreeDOS kernel implements the core MS/PC-DOS (R) compatible functions. It is derived from Pat Villani's DOS-C kernel and released under the GPL v2. Please see http://www.freedos.org/ for more details about the FreeDOS (TM) Project. This was originally a branch based on 2042 SVN 0xFD kernel; the full svn history has since been added to git (see other branches) and current development of release kernels are available here. Please fork and submit a Pull Request!

Compiled kernels ready to use (just copy kernel.sys over an existing install) are available at http://www.fdos.org/kernel/testing/git/ - also available are the source archive and fdpkg compatible packages. *** TODO update links/upload archives

This version of the kernel is intended only for 8086+ or 80386+ IBM compatible computers in continuation of the goals of the FreeDOS Project. Please see http://www.fdos.org/kernel for my 0xDC kernel that is work on merging back in some of the original portability aspects and other supported features at the cost of some compatibility with older hardware/software.

Now with automatic builds and soon tests Build
