Either one probably would have worked.  If I remember correctly, enabling
the DEBUG option also enables the ADB_DEBUG option.  However, enabling
'DEBUG' turns on a heck of a lot of extra crap that you probably don't
quite need...

Some of those files are examples.  I'm still not quite sure what MYSTERY
was for, tho.  Something Scott had going at one point, I think.  The
GENERIC kernel is pretty much just that.  A basic kernel which should
support just about every piece of hardware available.  The distribution
kernels are GENERIC kernels.  As for INSTALL, that's a ramdisk kernel that
was designed for use with a miniroot and sysinst.  We're not currently
using it b/c there wasn't enough time to fully test it before the 1.4
release (there was a blocking bug until about 2 days before the code
freeze).  I think there is a RAMDISK kernel as well.  It's similar to the
INSTALL kernel in that it was originally meant for some kind of
installation.

I hope that helps some.

Later.
