<p class="MsoNormal">I’m a colleague of Lynn’s and wanted to put my old C experience to use here, but have hit a snag. I’m attempting to insert my hook early in iPXE’s execution through __init_fn but it never executes. The debug text strings don’t even appear
in the final binary unless I stuff the code into something else, like ‘core/device.c’. Am I missing something in the following code?<o:p></o:p></p>
