I currently use a different method.
1) make the first partition active
fdisk /dev/sd[c]1 then a, 1 and w to write and quit
2) format the usb stick with fat or ext3
3) if you chose
(a) fat : you will need to make syslinux work on the stick
(b) ext3 : you will need to use extlinux work on the stick
4) I extract the isolinux folder from the dvd iso
5) rename all isolinux to (a) syslinux - (b) extlinux
6) copy the dvd/cd iso(s) to your stick
7) normally you should get the same boot loader as when you would pop in
the cd/dvd, centos install will start loading necessary drivers and then
you will have to chose hard disk install and point to the drive where
your dvd/cd iso(s) are
8) anaconda will start and well the rest you know
I have a 16gb stick with CentOS 4 32bit & 64bit and CentOS 5 32bit &
64bit to install my systems
There is one problem, if you want to use kickstart, it will want the
mounted iso files, have not yet figured a way to get around this or to
get some command to mount the images somewhere
