For PXE boot, you need to use BootP not DHCP. Change the object type to BootP and enter the MAC address of the device and push to the DHCP server.

We have PXE working with VitalQIP DHCP. We're using the following PXE related options.

66 - TFTP Server Name (IP or hostname)
67 - Bootfile Name
52 - Option Overload = Set value to 2

The PXE client would get an IP, mask, GW, etc but would stop at "PXE-E32: TFTP open timeout". When we set option 52 to 2 that solved that problem. Option 66 for TFTP server uses sname field which led me to this option. It was a shot in the dark that paid off for once.

Page 918 of the "VitalQIP Release 8.0 PR5 Web Client Users Guide"
Option Overload - This option is used to indicate that the DHCP sname or file fields are being overloaded by using them to carry DHCP options. A DHCP server inserts this option if the returned parameters exceed the usual space allotted for options. If this option is present, the client interprets the specified additional fields after it concludes interpretation of the standard option fields. Legal values for this option are as follows:
1 - The file field is used to hold options
2 - The sname field is used to hold options
3 - Both fields are used to hold options
