# --- default gateway

#       option netbios-node-type 2;
        range dynamic-bootp 10.10.10.150 10.10.10.160;
        default-lease-time 21600;
        max-lease-time 43200;
        # we want the nameserver to appear at a fixed address
#       host ns {

        next-server 10.10.10.197;
        filename "/pxelinux.0";
}
不要忘记写冒号 。我少写了。怎么也启动不了

#cp /usr/lib/syslinux/pxelinux.0   /tftpboot/
#cp /media/image/pxeboot/initr.img  /tftpboot/
#cp /media/image/pxeboot/vmlinuz    /tftpboot/
#cp /media/isolinux/*.msg       /tftpboot/
#mkdir /tftpboot/pxelinux.cfg
#cp /media/isolinux/isolinux.cfg /tftpboot/pxelinux.cfg/default

vi /tftpboot/boot.msg


在里面添加

vim /tftpboot/pxelinux.cfg/default

label autoinstall
kernel vmlinuz
append ks=http://192.168.40.163/ks/ks228.cfg initrd=initrd.img devfs=nomount ramdisk_size=9216 nofb
