other at 0x10000.

# 1.1 22-Jun-2004 tom

Enter cdbr, an El Torito no-emulation CD boot sector that fits
comfortably in a single CD sector of 2,048. Not currently hooked into
the build.

Based on the FreeBSD equivalent by John Baldwin, jhb (at) FreeBSD
(dot) org, who agreed to change to a 3-clause BSD licence. Thanks.
