Cisco Core Switch: Config For PXE Boot

Here is some config I did some time back on a core Cisco switch for PXE boot'ing.  These are the commands I put in on a 6500:
ip helper-address pxeServerIPAddress
ip helper-address dhcpServerIPAddress
ip dhcp relay information trusted

the only other command you might need for multicast is
ip pim dense-mode

On the 6500 Core switch:
interface Vlan102
 ip address
 ip pim sparse-dense-mode  <-----For Multicast Mode
interface Vlan103
 ip address
 ip helper-address   <-----DHCP server
 ip helper-address  <-----PXE server
 ip pim sparse-dense-mode      <-----For Multicast Mode
 ip igmp query-interval 125
