[syslinux] Has anyone any insight as towhy RedHatEnterprise Level 5 is broken as far as PXE bootingis concerned.

OK good NEWS

It seems that the dhcpd-3.0.5-5.el5.rpm and dhcpd-3.0.3-5.el5.rpm
versions need a next-server option  (even if tftp& dhcp are on the same 
box )& ought to be grouped with the client directives.

As below:

This minimal  dhcpd.conf file **WORKS**
###########################################
ddns-update-style interim;
ignore client-updates;
subnet 172.16.0.0 netmask 255.255.255.0 {
      option routers                 172.16.0.254;
      option subnet-mask       255.255.255.0;
filename "/tftpboot/pxelinux.0";
allow booting;
allow bootp;
      range dynamic-bootp 172.16.0.128 172.16.0.254;
      default-lease-time 21600;
      max-lease-time 43200;
group {
            next-server 172.16.0.254;
host abcd  {hardware ethernet 00:01:6c:ca:24:7b ;fixed-address 172.16.0.30;}
      }
}
###########################################










Thankyou everone for your HELP
