Chapter 13 . Running Gentoo Linux 397 30. Add kernel modules. Add any extra kernel modules that you need to add at boot time. You usually need to do this only if some piece of hardware isn t detected and the module needed to use it isn t automatically loaded. Edit either the kernel-2.4 or kernel-2.6 file, depending on which kernel you are using. # nano -w /etc/modules.autoload.d/kernel- You can type uname -a to see what your current kernel version is. 31. Configure the boot loader. You need to install a boot loader (grub in this example) and configure it. The example makes the following assumptions about your setup: Gentoo is installed on your first IDE hard disk (/dev/hda). You have a separate /boot partition on /dev/hda1. Your initrd file in the /boot directory is initrd-2.4.26-gentoo-r9. Your kernel file in the /boot directory is kernel-2.4.26-gentoo-r9. If any of that information is different for your setup, you need to adapt the following step appropriately. To configure grub, install it with emerge, run the grub command, and then create the grub.conf file as follows: # emerge grub # grub grub> root (hd0,0) grub> setup (hd0) grub> quit # nano -w /boot/grub/grub.conf default 0 timeout 15 splashimage=(hd0,0)/grub/splash.xpm.gz title=Gentoo Linux root (hd0,0) kernel /kernel-2.6.13-gentoo-r3 root=/dev/hda0 initrd /initrd-2.6.13-gentoo-r3 32. Reboot. Exit from your chroot partition by running umount to unmount all partitions and then rebooting as follows: # exit; cd / # umount /mnt/gentoo/proc /mnt/gentoo # reboot Remove the installation disk and allow the computer to boot from hard disk. After a few moments, you should see the GRUB boot screen. Select Gentoo Linux (press Enter). From here on you will be booting from the hard disk and working directly from the operating system you installed. If you see error messages, such as missing kernel drivers, I recommend that you go to http://forums.gentoo.com and search for the driver that s causing problems. Chances are that someone else has had the same problem and can offer you a solution. Note
