#打开tftp
chkconfig tftp --level 345 on
vi /etc/xinetd.d/tftp #看看内容，不用改

cd /tftpboot/
mkdir pxelinux.cfg
vi default
#######################
#default的内容如下
DEFAULT install
        PROMPT 1
        LABEL install FC5-x86
        KERNEL vmlinuz
        APPEND initrd=initrd.img devfs=nomount ramdisk_size=16384
#######################

拷贝光盘的/images/pxeboot/或者FC5/isolinux下面的initrd.img和vmlinuz到/tftpboot下，注意，必须用光盘上的,不能用硬盘的.
cp /usr/lib/syslinux/pxelinux.0 /tftpboot/

#启动tftp服务
/etc/init.d/xinetd restart
