Some basic RedBoot info can be found here:

...but here's a quick walk-through of how to set your machine up to
use BOOTP and TFTP.

Now, I generally load S-record versions of kernels, because it
saves me typing in the load address and entry point :-)  So, put
the S-record copy of the kernel you want to load on your TFTP
server:

   server# cp netbsd-wm0.srec /tftpboot/netbsd-verde.srec

..and load it on the client:

RedBoot> load netbsd-verde.srec
Entry point: 0x00200000, address range: 0x00200000-0x00396cb8

...and then start it:

RedBoot> go
