Hi experts, may I ask someone to take a look at the steps below I did to compile new kernel and let me know whether it looks ok before I reboot my PC? I've done this first time so I'm not very certain I did not miss anything and be able to boot old kernel in case new one does not work. Thx, Martin 1. uname -r to find out my current kernel version 2. install kernel source rpm 3. cp /boot/vmlinuz-$(uname -r) /boot/vmlinuz.old 4. cp /boot/initrd-$(uname -r) /boot/initrd.old 5. cd /usr/src/linux 6. zcat /boot/config > .config 7. make oldconfig 8. make xconfig - I did my changes here 9. make clean bzImage 10. make modules 11. INSTALL_PATH=/boot make install 12. make modules_install 13. vim /boot/grub.menu.lst to add title Linux-old kernel (hd0,1)/boot/vmlinuz.old root=/dev/hda2 vga=0x314 splash=silent apm=on acpi=off desktop resume=/dev/hda1 showopts initrd (hd0,1)/boot/initrd 14. my /boot looks like this now: drwxr-xr-x 3 root root 664 2005-04-10 13:39 . drwxr-xr-x 21 root root 488 2005-04-09 05:50 .. -rw-r--r-- 1 root root 512 2004-08-26 17:16 backup_mbr lrwxrwxrwx 1 root root 1 2005-02-21 15:45 boot -> . -rw-r--r-- 1 root root 57530 2004-12-22 07:51 config-2.6.8-24.10-default drwxr-xr-x 2 root root 512 2005-04-10 18:44 grub lrwxrwxrwx 1 root root 26 2005-04-10 13:39 initrd -> initrd-2.6.8-24.10-default -rw-r--r-- 1 root root 1181888 2005-04-10 13:39 initrd-2.6.8-24.10-default -rw-r--r-- 1 root root 1178088 2005-04-09 23:17 initrd.old -rw-r--r-- 1 root root 107008 2004-12-17 11:37 message -rw-r--r-- 1 root root 79151 2004-12-22 07:51 symvers-2.6.8-24.10-i386-default.gz -rw-r--r-- 1 root root 747406 2005-04-10 13:39 System.map-2.6.8-24.10-default -rw-r--r-- 1 root root 739824 2004-12-22 07:40 System.map-2.6.8-24.10-default.old -rw-r--r-- 1 root root 1857373 2004-12-22 07:51 vmlinux-2.6.8-24.10-default.gz lrwxrwxrwx 1 root root 27 2005-04-10 13:39 vmlinuz -> vmlinuz-2.6.8-24.10-default -rw-r--r-- 1 root root 1595169 2005-04-10 13:39 vmlinuz-2.6.8-24.10-default -rw-r--r-- 1 root root 1556643 2004-12-22 07:40 vmlinuz-2.6.8-24.10-default.old -rw-r--r-- 1 root root 1556643 2005-04-09 23:16 vmlinuz.old __________________________________ Do you Yahoo!?
