Hi Guys. I am running Mandrake 7.0 (kernel 2.2.14-15mdk) and want to upgrade the kernel to 2.4.test4 (for the improved USB support). However, I've never done a kernel upgrade/compile before. Now, I'm no expert with kernels, configurations, etc., so I want to keep all of my existing settings as they are, with the only difference being that the USB support is enabled. Is there a way of 'dumping' my current kernel's existing menuconfig/xconfig setup to a file that can be read into the menuconfig/xconfig for the new kernel? In other words, can I make my current kernel setup the default? One other thing - does anyone know how much disk space I need to have free in order to do the kernel upgrade? how-to: typically 65M or 100M somewhere (need to check). Thanks in advance. Ozz.

Assuming that by your "current kernel" you mean a binary kernel installed fram a Mandrake RPM, you should have the config file for that kernel in /usr/doc/kernel-version. Just copy that to /usr/src/linux/.config and manuconfig/xconfig will use it for the defaults. Alternately, use the load alternate config option to import the same file. That'll teach me to be so impetuous - I blatted /usr/doc to clear enough space for the kernel source :-( I tried doing everything manually, but seem to have screwed things monumentally - the new kernel just gives me the black screen of death. Fortunately I can still boot into my old kernel. I suppose I'd better wait until the next meeting of my local Linux User Group and let one of the Gurus loose on it... Thanks anyway for your help. Regards, Ozz.
Re: [expert] Compiling kernels.
in the /usr/src/linux-2.2.whatever that came with your mandrake they should have a file called something like deafultconfig -- whatever, it doesn't matter. I always do the config in X and then out to terminal for the complle. Anyway, from a terminal window in that directory, type "make xconfig" and it should load the mandrake kernel defaults. hit the save to file button, and save it someplace easy. next change to /usr/src/linux (symlink to Linux-2.4.0-test4 / oh by the way test 5 is out) and type make x config again. This time, load the file you just saved. I believe this will have all the mandrake defaults, except for the new functions, which will have the Linus defaults. I use this this way, because the download sources have defaults that are very different, and then I can just turn off those things that I understand and know I don't use (aplletalk, for instance) and can be certain of getting a good running kernel. BTW, anyone been using the packet mangling, NFS, and new in kernel stuff? What's the major config diffs from the old daemon method?

Re: [expert] Compiling kernels.
I don't think make oldconfig is what this person is after. From: http://www.linuxdoc.org/HOWTO/Kernel-HOWTO.html `make oldconfig' will attempt to configure the kernel from an old configuration file; it will run through the `make config' process for you. If you haven't ever compiled a kernel before or don't have an old config file, then you probably shouldn't do this, as you will most likely want to change the default configuration. I think make oldconfig I what your after.
