Chainloading #5

Hi JP,

Sorry for a long post, I have been using TinyPXE to chainload iPXE to install OS.

How do I chainload ipxe? In the configuration.xml, how do I specify an alternate file name or user-class i.e. winpe4.ipxe after downloading ipxe.pxe? My TFTP IP is the same as DHCP. Please see my config below. It downloads ipxe.pxe without a problem but it does not chainload the winpe file. I'm also testing with your TFTP server.

?xml version="1.0"?> <ArrayOfDHCPServerConfiguration xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <DHCPServerConfiguration> <Name>DHCP</Name> <Address>10.0.0.1</Address> <NetMask>255.255.255.0</NetMask> <PoolStart>10.0.0.50</PoolStart> <PoolEnd>10.0.0.200</PoolEnd> <LeaseTime>86400</LeaseTime> <OfferTime>30</OfferTime> <MinimumPacketSize>576</MinimumPacketSize> <Options> <OptionConfiguration xsi:type="OptionConfigurationTFTPServerName"> <Mode>Default</Mode> <ZeroTerminatedStrings>true</ZeroTerminatedStrings> <Name>10.0.0.1</Name> </OptionConfiguration> <OptionConfiguration xsi:type="OptionConfigurationBootFileName"> <Mode>Default</Mode> <ZeroTerminatedStrings>true</ZeroTerminatedStrings> <Name>ipxe.pxe</Name> </OptionConfiguration> <OptionConfiguration xsi:type="OptionConfigurationTFTPServerName"> <Mode>Default</Mode> <ZeroTerminatedStrings>true</ZeroTerminatedStrings> <Name>10.0.0.1</Name> </OptionConfiguration> <OptionConfiguration xsi:type="OptionConfigurationBootFileName"> <Mode>Default</Mode> <ZeroTerminatedStrings>true</ZeroTerminatedStrings> <Name>winpe4.ipxe</Name> </OptionConfiguration> </Options> </DHCPServerConfiguration> </ArrayOfDHCPServerConfiguration>

In the DHCP Log, the Next Server Address is 0.0.0.0. How do I set this up?
