Please I need help with this custom grub:

default=0
timeout=20
fallback=1

title Remote Install
root (hd0,0)
kernel /vmlinuz_remote lang=en_US keymap=us ks=nfs:192.168.128.42:/tftpboot/Kickstart/ks.cfg ksdevice=00:1A:64:22:32:4B headless xfs panic=60
initrd /initrd_remote.img

I have 3 grub configs and I've been able to make the "Remote install" grub config to be the default run. At the moment it boots up but hangs at the prompt.

Grub version: 0.98

The other 2 grubs that comes that exists after successful installation and update of the kernel are:

splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
