First, you need to set up a DHCP server somewhere to serve the BOOTP image
to the SABLE.

Then, create the BOOTP kernel image via first a normal kernel build,
then issue:

	make bootpfile    # uncompressed image so fairly large
	make bootpzfile   # compressed image but only on recent versions

Grab the image from arch/alpha/boot/bootpfile (or bootpzfile) and
supply it to the DHCP server, renaming as appropriate.

1. building drivers into the kernel (ie the 2940U2W driver for one)
   is HIGHLY recommended (for simplicity's sake :-) over having to
   build and boot with an INITRD.

2. "ewa0" is assumed to be the NIC that is connected to the network
    where the DHCP server is located.

Good luck.
