Subject: How to change PCI Configuration space?
Date: Tue, 30 Aug 2005 13:47:12 +0900 [thread overview]
Message-ID: <b115cb5f0508292147de16584@mail.gmail.com> (raw)
Hi List,
I want to change the PCI Configuration space of a particular device in
my system. 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?
TIA,
Rajat Jain
