How to check if AGPGART is compiled in the kernel
My display driver(i815) requires that for any high resolution display according to the XFree86 guys. I can only use the VESA driver at 640x480 without that.

To check if APGGART is compiled into kernel look in the config file found in /boot:
As root try:
Code:
grep AGP /boot/config-2.4.20-xfs
it then returns:
- CONFIG_AGP=m
CONFIG_AGP_INTEL=y
CONFIG_AGP_I810=y
CONFIG_AGP_VIA=y
CONFIG_AGP_AMD=y
CONFIG_AGP_AMD_8151=y
CONFIG_AGP_SIS=y
CONFIG_AGP_ALI=y
CONFIG_AGP_SWORKS=y
The above tells you that the kernel has AGP support but only as a module (m).

Thanks. But I cannot find the file i810.o under lib/modules/kernel/video and if I let KNOPPIX to start XFree86 using i810 driver, it said fail to allocate memory and mention the file i810.o.
Does that means Klaus forgot to include the necessary module ?

Are you sure it is the driver you need?

Thanks, found it but it still failed miserably. I am sure about the chipset(i815) and the auto detect also found it and use the i810 module of the XFree86. But it give me an error message of "cannot allocate memory" and a long list but before I have the time to read them, it switch to the graphic mode and hangs there. I need to remove the power supply to gain back control.

Use 'knoppix 2'

I can either use xmodule=vesa or 2(to get the text prompt). However, this make the machine quite usless as the 640x480(vesa) display is just too difficult to use, many website just don't show properly.
I have tried 'knoppix 2' and check to load the agpgart and i810 module manually and they load without any error. However, if I then startx, the machine hang which again needs the removal of power to gain back control.
a lot of thanks for the help anyway.

What if you use the noagp option?
And when you run failsafe it still hangs?
What happens when you use the fb options instead?

failsafe is fine as it would automatically use VESA driver(that is how I find out how to make the X work). I tried noagp, it failed. I also tried the fbdev, still failed.

On mine failsafe starts up in 1024x768
I found this:

It indicates that you should use the 800x600 or else X hangs. (screen=800x600)
