Just follow the instruction I mailed already to Neil Aggarwa It also works for cd iso images instead of dvd iso images

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 syslinux /dev/sd[c]1 (b) ext3 : you will need to use extlinux work on the stick extlinux /dev/sd[c]1
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
