| + | Compiling the ext2 and ext3 file systems into the kernel, rather than modules makes sense for now. I am uncertain if one could ever compile ext2 as a module and still boot due to the initramfs.\\ | ||
| + | The above options are not the only thing you will need to get your nodes up and booting.\\ | ||
| + | You will need motherboard specific modules, for the computer you will be booting. An easy way to get a list is to boot a gentoo install cd, or another system that you trust. Once in the shell, get a list of loaded modules. ( lsmod ) Write down the list in use. Then deselect any modules you do not need, making sure you have selected the modules that you do need. | ||
