_before_ getting that message, look in the bios. there should be some
mention of net-boot and/or PXE. assuming you have integrated net, of course.
bootable add-in NICs are still pretty hit-or-miss, I think.

sure, you need some sort of ethernet. doesn't have to be a 16pt switch
(please don't say that you actually have a hub!)
