I can get paste the first round of dhcp, where I detect that this is a PXE asking for a arm payload, and I hand it an iPXE executable, which sets things up and chains to pxeloader, which seems to ignore the key=3Dvalue stuff that multiboot compliance should be processing. I have diskless booted Linux on my Pi's this way, would love to have the BSD side working too. > thanks, > danny > > Rod Grimes rgrimes@free= bsd.org --=20 Rod Grimes rgrimes@freebsd.= org
