I am trying to use the "pcitweak" utility to do so, but am not suceeding. I would appreciate if some body could provide me any pointers in how to do so. In this case, I want to change the value at offset 64: $ pcitweak -r 5:9:1 64 0x01000001 //original value $ pcitweak -w 5:9:1 64 0x02000002 //new value $ pcitweak -r 5:9:1 64 0x01000001 //no change?
