You say "Note the kernel module that gets loaded for this machine" I'm
assuming this is for the new SATA box. Since I can't boot into the
machine, is there any other way to gather this information? I can boot
into knoppix, mount the SATA drive and read files off of it. I can
even edit the modprobe.conf to add whatever needs to be added to it,
but what should I add?

This needs to be run on the new machine too? Any alternate way of
running this if the machine is not bootable?

You are right. It is FC1. I checked the fstab file by mounting the
drive after booting in Knoppix and one entry was for hda, which I
changed to sda. If I have to edit the modules.conf, what should I use
for the module name to add and where would I get the driver file from?
When I do get that file where do I place it for the system to find?

Thank you for your patience and help!
