Module detection in linux

I have recently compiled linux 2.6.9. It has taken me quite a bit of time to get one that actually works, but I did it. However, there are a few error messages that I REALLY don't think should be there. The first of which is agpgart module not found. I think it says somethings slightly different, but I can't tell(I do not know of file I can look in to actually grab the messag. Please tell me how.). Anyways, I looked in my kernel .config file and that driver is selected as a compiled in module *. Is it possible that my init files can't find the modules because it's compiled directly into the kernel? I would think the init files would search the kernel for it. I'm using slackware 9.1. I have done no editing to my init files at all. Thank you, Bobby.

The problem you are seeing is likely because your init files are running a command like "modprobe agpgart". If the code was compiled directly into the kernel (and not as a module) running that command is not necessary and will not work. Code compiled into the kernel is automatically enabled by default. You need not do anything special to cause it to become active. Typing dmesg should confirm this as you should see messages similar to the following:

agpgart: Detected an Intel 440BX Chipset.
agpgart: Maximum main memory to use for agp memory: 565M
agpgart: AGP aperture is 64M @ 0xf8000000
To get ride of the error either edit the rc files so it doesn't attempt to load the agpgart module or recompile your kernel with agpgart setup as a module instead of compiled in-line into the kernel.

Very nice. I was wondering whether or not modprobe would actually trigger that error. Now, I have reason to start editing my init files. This should be fun! Thanks again.
