iPXE and OpenBSD

[robinsmidsrod]

Most likely the OpenBSD kernel format is not supported by iPXE directly, which is why you need to use pxeboot (which is a PXE binary, supported by iPXE).

I can only assume that when you try to automate pxeboot, it has some problems with a prefix so it doesn't actually load the file you think it does. Have you tried enabling debug logging on your tftp server to see exactly what file it asks for? If you can't get it to tell you that, you might also have luck with a packet trace on the tftp server to see what's being requested.

It would be beneficial if you show us the iPXE script/commands you use to load pxeboot (in the automated way) and how you do it manually. Maybe it can shine some more light on the subject matter.
