Jeff,

I commented out everything you showed me and recompiled.  This seems
to have worked.  The hard disk shows up as sda.  What does it mean
that this worked? Is this a bug with ata_piix?  What changes will need
to be made to get this machine to work on an unmodified kernel?

Thanks for your help so far.
Greg
