My customer just bought a PowerEdge R620 with H710, and their OS is Debian 6.0. they failed to install Debian 6.0 on R620. I searched Debian bugs, and found this bug was fixed. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=666108
I have poor linux skill, having difficulty to understand the discussions. Could you please give me an easy instruction on how to install debian 6.0 on R620 with PERC710?
