HOWTO

# Dev86
# =====
# If you only need as86 and ld86, you may want to install bin86 instead.  dev86
# includes quite a bit more.  There are two versions below, 0.16.17 is the
# latest, and if you need the most stable, go with 0.16.0 at the bottom.

# This used to be required for building kernels (2.2.x).  lilo uses this for
# it's diagnostic floppy.  I'm sure lots of other things use it too.  It's
# an assembler, so it's not application specific or anything.

# If you ever want to uninstall it, skip down to the bottom for
# instructions.

# Dev86 0.16.17
# =============
