Re: hpt366-0.37.patch.bz2 K.O.

So the point is that I know there will not be a version greater than two
on this asic?

I post fixes for problems people pay to have fixed.
If there are other problems, you are free to fix it yourself.

I have been doing this for only the past 6 years, there is just a tiny bit
of insight I might have.  Hey apply or not.
