The first of those (http://192.168.65.3/menu.ipxe) will work fine since 
that will be fetched by iPXE, and iPXE understands HTTP URLs.

The other two entries are to be fetched by the BIOS, which doesn't 
usually understand HTTP URLs provided by DHCP.

Some UEFI BIOSes include support for very basic HTTP booting; you will 
almost always have to configure this manually via the BIOS setup screen. 
  There is some documentation at https://ipxe.org/appnote/uefihttp

Hope that helps,
