OK, I guess, I'll use the minimal CD and the older (handbook) style install.

I was hoping to use the amd64 liveCD, but the (Gig)ethernet is acting funny;
it gets ping replies during the live cd install, but when ping from another
machine, it never answers. It can get to the gateway, with ping replies
as seen on while booted into the livedCD, but no further (yes resolve.conf)
is set up. It answers no pings from other systems.......

The mobo, a 'MSI K9A' with an AM2 socket board with dual (Gig)ethernets,
 8 channel surround, PCI-X and setup for the ATI 1900 crossfire dual video
cards. I only have one  ATI 1900 video card installed. 

I've gotta put the install aside, for a few days, to get some other
work finished. Between the hardware and the need to figure out how to 
compile/run code directly on the ATI 1900 video card, I'm sure I'll
be posting again on this project. When I try the install again, I'll post
more about the chipsets and driver issues, if I cannot resolved them
myself.

thx to all for the comments,
James
