Hi all :
my /dev/sda2 is ext3 format filesystem, the os moblin is installed in
/dev/sda2 which is root partition, the bootloader is grub, now i want to
change the bootloader to extlinux, but i came across some trouble, so i did
some steps as following:
1. rpm -ivh syslinux-extlinux*.rpm
2. extlinux -i /boot/extlinux
3. i edit extlinux.conf , and put it in /boot/extlinux/, there is
extlinux.conf is my attached file.
4. cd /boot/extlinux
ln -sf ../vmlinuz-2.6.32.4.lp.enhance.24-netbook-atkbd
vmlinuz-2.6.32.4.lp.enhance.24-netbook-atkbd
5. extlinux -U /boot/extlinux/
6. cat /usr/share/syslinux/mbr.bin > /dev/sda
7. reboot
the screen always show "No DEFAULT or UI configuration directive
found!",
and then i type "/boot/vmlinuz-2.6.32.4.lp.enhance.24-netbook-atkbd"
or
"/vmlinuz-2.6.32.4.lp.enhance.24-netbook-atkbd",
"vmlinuz-2.6.32.4.lp.enhance.24-netbook-atkbd", but the screen always
show
"Could not find kernel
image:vmlinuz-2.6.32.4.lp.enhance.24-netbook-atkbd".
could you help me? tell me how i will do and debug extlinux in my case.
I am sorry my English is very poor. please help me!

Again, assuming you have a separate /boot, you should not put /boot in front of the filenames in extlinux.conf, but that again doesn't explain the error messages. You are also not including which version of Syslinux you are using. (Not sure why you are doing the linking in step 4.) We are just about to release Syslinux 4.00, which is a major change in codebase. You may want to test it out. It is available in tarball form at: http://www.kernel.org/pub/linux/utils/boot/syslinux/Testing/ -- H. Peter Anvin, Intel Open Source Technology Center I work for Intel.
