How can I foind out, what kernel options is my kernel compiled with?

By looking at the .config file?

It's in the kernel's source directory, if you don't
have that installed, there should be a file
/boot/config<mumble> that maps the config
of the current kernel.

If all you have is the compressed image and not the source and .config file that was used to compile it then I am not sure there is any way to tell for sure.

Looking at the dmesg you can tell some things, looking at the modules in the /lib/modules/your-kernel-version/ directory will tell you others. But not everything.

thanx, i've got installed Linux only in text mode, and want to enable framebuffering. Is it very dificult to recompile kernel then with that option enabled?

Not at all, there is a kernel compile HOW-TO on this site that will probably do a much better explination then I would, read it and give it a shot.

where's that howto exactly please, thanx

Here you go: http://www.linuxquestions.org/questi...threadid=73436

The guy I used the first time I ever compiled a kernel was foudn at www.tldp.org but they have taken it down for "Review" because a lot of it talked about 2.0/2.2 stuff that wasn't important anymore for most peopl needing to read it. Guess they thought it was time to re-write it for 2.4/2.6. In general though, http://www.tldp.org is a good place to start looking when you have a question for anything (tldp = The Linux Documentation Project).

Sorry for my questions but:
1. Could I somehow change kernel options without compiling a new one? 2. Could I recompile my current kernel with the same from my RedHat instalation CD?

If you have the configuration file and the source code from RedHat then you certainly could do that. I am not sure if RedHat includes the kernel source but I would imagine they would have to somewhere.

Oh, I see you use Slackware. Which didtribution do you prefer. I've just ordered Slackware 9.1 from our local distributors, it's very cheap, about 3$!!!!

I love slackware, and I love gentoo. Gentoo fits better for a desktop system in my opinion, because it is so much easier to upgrade. Of course slackware has a dependancy checking package management system now, but I haven't tried it yet. My slackware box hasn't been touched except for security updates in over a year. It sits in a closet with only a power cord and an eithernet cable attached to it. The uptime of the box was over 400 days until earlier this month when I put the 2.4.24 kernel on it. Hopefully that will be it's 1 reboot of the year 2004.

Here in Slovakia, is Gentoo quite unknown. I checked out it's website, but i didn't have too much time. I work with linux only in text mode and I use it for programming. What's your opinion about Redhat or Suse?

I have never used Suse and I haven't used redhat directly in about 4 years so I don't have much of an opinion on it. Slackware is a great text mode distribution. It doesn't require or have any gui config tools.

I've got my kernel compiled with framebuffering support. But there isnt at /dev any file like fb, fb0 or something like that. So the framebuffering doesn't work. I use now RedHat 9.0 and Mandrake 9.2. Is there any boot parameter to run linux with framebuffering? Help me plaease

Ok, so i figured it out.
here's the answer http://en.tldp.org/HOWTO/Framebuffer-HOWTO-5.html

to 1024x768 the boot parameter is vga=791, but must have CONFIG_FB in config =y.

Oh, by the way, I've got TNT2. I heard something about rivafb, but didn't find anything useful in english at google (only in russian, sh..!). Any idea where to find some kind of how-to or docs?
