I had to create a custom initrd file to make it work for me. (this was on an IBM x3655, but has the same NIC) Unpacked the driver from the manufacturer, grabbed the .ko file, and rebuilt the initrd with that driver for the kickstart.
Is there any chance you could make this initrd available ? I have tried to use the driver from hp and rebuilt using that but it did not work either. If you could make this available i would be very grateful!
thanks
