I assume you meas RHEL 3 and RHEL 4 and not the *original* RedHat 3 or 4.

Look in the isolinux directory on the first CD of the distros in
question. You'll find these files (or similar):

sauron.deepsoft.com% dir /mnt/centos43/d1/isolinux/
boot.cat initi586.img isolinux.cfg* param.msg splash.lss
boot.msg initrd.img memtest rescue.msg vmlinuz
general.msg isolinux.bin options.msg snake.msg vmlzi586

Look at /mnt/centos43/d1/isolinux/isolinux.cfg -- this file is the
install CD boot configuration. You basically want to use this as a
guide to creating a bootable USB drive (i.e. with grub or lilo for
example). For example, /etc/lilo.conf on my desktop system contains
these sections:

image=/boot/vmlinuz-WBL3Install
label=WBL3Install
initrd=/boot/initrd-WBL3Install.img
append="text"

image=/boot/vmlinuz-RH73Install
label=RH73Install
initrd=/boot/initrd-RH73Install.img
append="text"

image=/boot/memtest86/memtest.bin
label=MemTest86

image=/boot/centos43vmlinuz
label=CentOS43Install
initrd=/boot/centos43initrd.img
append="text"
