The pxeboot initrd and vmlinuz are in the boot directory on CD 1.

Copy those to the tftpboot directory, along with your pxelinux.0, and
put the syslinux config in the pxelinux.cfg/default file, mine looks
like so:

default server
prompt 1
timeout 100
display pxeboot.msg

label server
	kernel vmlinuz
	append initrd=initrd.img ramdisk_size=8192 root=/dev/ram0 ip=dhcp lang=us expert ksdevice=eth0 ks=http://10.1.1.60/CentOS/5/server.cfg method=http://10.1.1.60/CentOS/5/os/i386 noipv6 quiet
label desktop
	kernel vmlinuz
	append initrd=initrd.img ramdisk_size=8192 root=/dev/ram0 ip=dhcp lang=us ksdevice=eth0 ks=http://10.1.1.60/CentOS/5/desktop.cfg method=http://10.1.1.60/CentOS/5/os/i386 noipv6 quiet

I setup the packages on a web server along with my kickstart that looks
like so for desktops:

install
reboot
lang en_US.UTF-8
keyboard us
firewall --disabled
selinux --disabled
firstboot --disabled
timezone --utc America/New_York
network --device=eth0 --bootproto=dhcp
