Thanks for your response Mark.

I was able to get the Grub menu but there was only one kernel choice.  
I'll try in single user mode and get back here.

As for Supermicro, i was using Tyan before but their support (and 
associated website) was very bad (last time i used it was 2 years ago, 
maybe it's better now, dunno...).  If we exclude Supermicro and Tyan, 
i'm not sure were i could go for "OEM" servers.  I don't like HP, Dell, 
etc.: Expensive and they use a lot of "for them only" parts + they try 
to sell packages that are often not what i want.

Thanks again.
