problem booting from CD after burning.

	after burning a RedHat CD 7.2 iso , using " anaconda , buildinstall
, splitdistro and all 
	the stuff ".
	I try to install from that CD using an LS 120 diskette.
	after choosing the "CD ROM install source" I get 
	"cannot read modules/modules-info"
	and the install process says me goodbye end reboot the computer.
	I know that I've missed something the question is what ?

Here's the procedure I used :
#pwd
/home/alex/ia64
# ls
autorun  COPYING  images  kernels  preview  README  RedHat  RELEASE-NOTES
RPM-GPG-KEY  SRPMS
#export PYTHONPATH=/usr/lib/anaconda
#export PATH="$PATH:/usr/lib/anaconda-runtime"
#cd /home/alex
#genhdlist --withnumbers /home/alex/ia64
#pkgorder /home/alex/ia64 ia64 | tee /home/alex/pkgorder.txt
#buildinstall --pkgorder /home/alex/pkgorder.txt --version 7.2
/home/alex/ia64
#cd /home/alex
#splitdistro --fileorder /home/alex/pkgorder.txt /home/alex/ia64 .

and finaly making the ISO images.

Thanks for your Help.
	Alex.
