[mm185399]

What is the utility you suggest for tftp and dhcp, i am using tftpd32 which has both in it, the problem is I need to manually replace ipxe.efi with test.ipxe the test script after ipxe.efi is loaded else it will run in a loop of fetching ipxe.efi.. Can we make this two step process a single one
