Re: [9fans] broken floating point exceptions and fpregs

[Francisco J Ballesteros <nemo@lsub.org>]

did not publish it yet, but we have what 
could be called a nix mark II, comes
with a new mount table and a fossil
speaking 9pix, plus a new scheduler. 

It does not have al the stuff like graphics in the modified mark I nix 
you have, but, the new stuff should be
easy to use on it. 

give us a bit more time and we will put 
the new bits somewhere.
