I am netbooting many systems, and last recently stepped on the issue, that I
had an amd64 and an i386 client in the same network. I wanted to boot them
into a "full" OpenBSD (not ramdisk kernel). That is not possible with the
default installation, cause pxeboot can not distinguish between these
Intel/AMD systems. DHCP server can distinguish by MAC address, but then when
pxeboot is loaded, the kernel is per default "bsd". This must clash either
with i386 or amd64 architecture, whatever was dropped into tftpboot direcotry.
So I went through some older mailing list entries, adapted them, and updated
my meanwhile extensive netboot document. I updated this into a PDF, covering
many, many details (now ~50 pages). Wanted to give something back to the
community. The PDF is currently located here:
