Hi Seb

I'm not sure I understand...he said:

"I turned raid on in the bios for the two channels that I have the hard
drives hooked up to but when I got to the partitioning section of the
installation I was confused.  The only way I could figure out how to get
the raid going was to use the "software raid" function in the partition
If he turned on Raid in the BIOS, is that not Hardware Raid?
When I installed software Raid1 on those two servers recently, I didn't
implement anything in the BIOS, it was all done in Debian.
