During both a default installation and a linux26 installation, the 
problem occurs at the partitioning stage. Manual partitioning is the 
only option because no drives or partitions are detected. The drives are 
known to be functional since an existing commercial OS exists on one of 
the drives and is bootable.
   
We need lspci and lspci -n output for your machine to fix this.
Also, I'd recomend trying an installation image that is not three weeks out
of date..
