I'm running 1.2.1 on a Classic II and never got the HWDIRECT kernels to
work or any of the generic kernels.  From archives of this list I found
my way to the older ADBTEST160 kernel which _did_ work (and, again, is
the only kernel I have ever gotten to work).  No problems at all with
this one.

Available from the same ftp site as the HWDIRECT kernels, but I forget
what directory, "old" or "obsolete" or something.

Hope this helps,

Pat
