my root partition is hda3 only . do i need to compile ext3 with built in support in this case also. and i m not sure about initrd . i read this in a tutorial to remove the entry .
"The reason you should remove the
initrd field is because the initrd file does not contain anything that would be useful to your new kernel. In a normal Linux distribution, the initrd
contains a lot of kernel modules which can only be loaded by the distribution kernel."but i m not sure about this. and i dont know how to create this file . i followed some steps from a tutotrial to create this file but could not succeed .
do i need to compile ext3 as built in instead of module even if my root paritition is hda3. how do we generate the initrd.img file
thanks in advance
regards
devendra

And yes, there is a prob in your grub file, compare your first entry
with the 2nd one and you will find that you are not mentioning initrd
in your first entry ! This can be a prob too ...
