I don't think copying your .config from your 2.2.19 is a good way to start. There have been a lot of changes. The config file for a 2.4.18 is about three times the size of a 2.2 config file. I would suggest starting with the .config file that came with kernel-source-2.4.18. > the questions as no, which was default. This is a 600 Mhz celeron > system. Plain Jane.

If you compile your own, you don't have to use initrd. If you don't use initrd, make sure the .config file has these settings: # CONFIG_BLK_DEV_INITRD is not set CONFIG_IDE=y CONFIG_BLK_DEV_IDE=y CONFIG_BLK_DEV_IDEDISK=y CONFIG_[your-root-file-system-module]_FS=y CONFIG_JBD=y #if your root file system is ext3 > > I've got another system that I attempted to compile 2.4.18 on.
