Grub uses its own drive designations, drive 0 = hd0, drive 1 = hd1 , so in this instance the correct command would be root (hd0,4)

HTH

what's on your hda4 ?
you root should be LFS system root or other linux system root I think.

The kernel panic is caused by the kernel not being able to mount a root filesystem.

The following are the likely causes

The fstab entry for the root filesystem is incorrect, ie, wrong fs type or wrong partition.
The kernel doesn't have builtin support for the root filesystem type.
The kernel doesn't have builtin support for the hardware the root filesystem resides on.

did you enable sata support in kernel?
