(EE) GARTInit: Unable to open /dev/agpgart

Dear all

I have RedHat Enter. serv. 3, I have upgraded the kernel from 2.4.21 to 2.6.3, now the system boots up fine but when i tried to start the GUI
with startx command it gives the following error

(EE) GARTInit: Unable to open /dev/agpgart (No such device)
(EE) I810(0): AGP GART support is not available. Make sure your kernel has
agpgart support or that the agpgart kernel module is loaded.

I have a P3 machine with intel 810 chipset & using the onboard video, I don't have a AGP card installed .

Is there problem in kernel ?

PLZ. help

Thanks in advance

FYI, RedHat does not support running the 2.6 kernel on RHEL 3.

In answer to your problem, make sure that AGP support is compiled into your kernel. Also make sure all relevant i810 drivers/options are enabled in your kernel configuration.

I have attached the standard .config for RHEL3.

To fix the existing X problems, you may want to run `X -configure` and follow the instructions there. This will make X probe your hardware and attempt to write a new xorg.conf for you, in your ~/ directory.
