Bare Metal bootloader built, now how do I use it?

Hello again from Gregg C Levine
Thought you should know, that I've built my copy of the Bare Metal
bootloader. According to your notes below, it gets used with an Ether
boot, and the memory tester. And that I'd need to build my Linux BIOS
builds with that serial setting turned on. One quick question before I
do all that, can I simply test Bare Metal, by sending it via an
etherboot device to the system in question? Your notes say I can. But
how?
