Intel only provides ESRT2 driver for Tested operating systems. If you need a free Linux solution you may try CentOS*. It's not officially supported by Intel, but since it's a clone of RHEL*, most likely the RHEL driver will work. I know some customers had install CentOS* successfully using RHEL driver. However if you encounter any issue with CentOS* you're on your own - Intel is not supporting it.
Thank you for your information Edward.
Unfortunately, this leave me with very little to go on. I was considering cent, but hoped for more opportunities. I have supported Intel and have patronized the products professionally and personally. Under the circumstance I am forced to go with third-party manufacturers.
