QuickList: Kernel Upgrade for Gentoo

QuickList: Kernel Upgrade for Gentoo

# uname -a
Linux mythtv 2.6.23-gentoo #2 PREEMPT Tue Oct 23 12:57:42 PDT 2007 i686 Intel(R) Celeron(TM) CPU 1300MHz GenuineIntel GNU/Linux

# eselect kernel list

# eselect kernel set 4

# cd /usr/src/linux

[copy over your previous .config file from the previous kernel compile ]

# cp /usr/src/linux-2.6.23-gentoo-r2/.config

# make oldconfig && make prepare

[ answer all questions using default ]

# lspci

# cat /proc/cpuinfo

# make menuconfig

[ answer all questions using known hardware values from lspci and cpuinfo ]

# make

# make modules_install

# mount /boot

# cp arch/i386/boot/bzimage /boot/kernel-2.6.25-r8-2008-09-19

(these next two are optional - .config stores the options used to create the kernel, and System.map stores the hardware info (?) )

# cp .config /boot/config-2008-09-19

# cp System.map /boot/system-2008-09-19

# nano /boot/grub/grub.conf

[add in an entry near the top pointing to the new kernel file, using a previous entry]

# reboot
