So you need to grab the 2.6.24 kernel, the 2.6.25-rc8 and the 2.6.25-rc8-mm1 patches, and compile a new kernel. If you've already done kernel patching/compiling, then it shouldn't be a problem. If not, I recommend reading resources from the net, like this: http://www.linuxdocs.org/HOWTOs/Kernel-HOWTO.html Miklos |
