Uhmm - correct me it I'm wrong, but IIRC you can boot DECstations via
tftp.

netblk.c can be configured to your likings. The modification process
is described in the Ultrix-FAQ. I did this for a VAX I wanted to
netboot.

A quick shot whould be to build a proper kernel (you have to link
netblk.o into the kernel) anf rarp/tftp the stuff. I'm not sure
whether the (r)arp process will override the kernel settings, but I
fear not ;( Maybe supplying an installation kernel might help?

Just my 2¢,
