Ok, here is the latest with this.  I made the switch in the BIOS to
use AHCI instead of IDE for my 2 SATA drives.  I then tried to install
FC6 with the boot options:

linux all-generic-ide pci=nommconf

This time I was able to start the installation and proceed thru the
locale/language settings.  However, when I get to the point of the
install where I'm to partition the drive(s) for installation, no
drives appear.  There are no drives in the 'Select the drive(s) to use
for installation' box, and clicking Next results in


********************************************
No Drives Found
An error has occured - no valid devices were found on which to create

problem.

I have also updated the BIOS to the latest available (dated 1/5/2007)
from Intel.

Any suggestions/ideas?
