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

[steven james]

Greetings,

You can 'sort of' manage it in theory. Put the bootselect.elf on your boot
server and set up dhcpd.conf filename= line to send bootselect.elf.

Since your flash won't have any tags, you'll see it come up on serial,
then fail (since it won't find any tags).

G'day,
sjames
