I would like to know if there is any way to enable a specific feature in the CPU, if that feature is not given in the BIOS. For example, i have Xeon E5-2680 V2, according to the data sheet this processor supports NTB on PCIe Port3a. But this NTB option in not given in the BIOS of HP Z420 workstation. I want to know if there is a possible way to change this PPD register given at page 138 of pdf.
Thank you
Below command did the job. sudo setpci -H 1 -s 3 4d.B=02
