hello guys

hi guys
I want to end up with a bootable DVD that will automagically start the kickstart script and perform an unattended install. I have read a few things that say that ks.cfg must be in the root of the image. I've read other things that say that isolinux/ is really the root, and so the ks.cfg must be there. Neither work. In my isolinux.cfg, I have:

label ks
kernel vmlinuz
append ks=cdrom:/ks.cfg initrd=initrd.img ramdisk_size=8192

ks.cfg is in isolinux/ as well as the top-level directory. What am I missing? How do I get the booted OS to read and use ks.cfg?

also i had added "default ks" in isolinux.cfg file
i had used the following command to make the isoimage of ks.cfg i had placed my dump of fedora8 in /bkup/dump3
"mkisofs -o ../cdrom.iso -A 'ISOLINUX' -V 'ISOLINUX' -b isolinux.bin -c boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table ."

also the .treeinfo and .diskinfo both hidden files are present.
then i created the isoimage of my dump with the command
"mkisofs -o /fedora.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table /bkup/dump3."
then i burned the iso image "fedora.iso" to a dvd with the help of k3b
the dvd is bootable but at boot time when prompt comes i gave the command "linux ks=cdrom:/ks.cfg"

but its giving me the error
RAMDISK: compressed image found at block 0
crc error
VFS:cannot open root device "<null>" or unknown-block (253,0)
please appened a coorect "root=" boot option; here are the available partitions:
kernel panic - not syncing:VFS:unable to mount root fs on unknown-block(253,0).
