accessing chipset identification

r.stiltskin · 12-06-2005, 01:39 AM

I'm trying to identify the revision number of my i845 chipset. According to Intel (ftp://download.intel.com/design/chip...t/25180901.pdf)
"the revision number corresponds to bits 7:0 of the Revision ID Register located at offset 08h in the PCI function 0 configuration space."

How can I find out that value?

Some useful commands:

/sbin/lspci

cat /proc/pci

Either of these might get what your looking for...

dmesg
lshw

try those too

The setpci command from the pciutils package can query pci devices

To show only function 0 of all devices:

Code:

lspci -s .0

which should give something like this:

Code:

0000:00:02.0 VGA comaptible controller: Intel ...

It says (example) that your graphic card is on bus 0, slot 2.

Put it in setpci:

Code:

setpci -v -s 00:02.0 REVISION

and you should have your revision number

00:02.0:08 = 02
