Trying to install GRUB but getting "L 99 99 99" error!

[John Sabean]

I've been working at building a kickstart disk for a RedHat Enterprise 4  
configuration that I have (using the demo/trial version).

My ks.cfg file has the following bootloader command:

bootloader --location=mbr --md5pass=$blahblahblah

When the host reboots, it prints out "L 99 99 99 99....". Thats a LILO  
error, isn't it??? (and yes, this disk previously had LILO loaded on it)

I've even gone in, in rescue mode, run chroot, and performed 'grub-install  
/dev/sda', and rebooting I get the same error.

I'm at a total loss!

Here are some goodies from my ks.cfg file:

Any help would be greatly appriciated.
