I believe that will cause you problems once you manage to get netboot
loaded and running. Netboot needs rp to nfs mount the path to the kernel
I can't see any obvious reason netboot isn't getting loaded. One thing
that could be done is to run tcpdump and capture all the traffic to/from
bjork and see if it's even attempting a tftp transfer.
Another difference I see between your bootptab and the one I've used to
netboot alphas is that your bootptab doesn't have an sa entry for the
address of the tftp server. That shouldn't be a problem though, since
bootpd should be sending back it's own IP address if the sa entry is

This doesn't look too good, I think that's supposed to be the size of
the image loaded from the MOP server.

What do you have in /tftpboot/mop?
I don't know of a boot.mop file for the alpha, although a brief look
through mopd seems to indicate that it might not take too much effort to
convert the netboot file into a mop-loadable image.
