OK.  The 742 is basically the VME version of the 715/Scorpio,
725/Spectra which are, or should be, minimally supported.  So in theory,
it should work.  In practice, there may well be glitches like the ones
you describe below.

There's an rboot daemon available for Linux; if you run Debian, just apt-get
install it; if not there's one on the puffin.external.hp.com site somewhere.

I just booted a couple of 715s from an rboot server...

First of all, you need to specify the machine in the /etc/rbootd.conf file.
Looks like you have this working already, but here it is:

08:00:09:35:21:18       guernsey

Then you need to set up bootp/dhcp.  The dhcpd is capable of serving both;
I use bootp.  Here's the stanza I used for this machine in /etc/dhcpd.conf:

host guernsey {
        # 715/50
        hardware ethernet 08:00:09:35:21:18;
        fixed-address 15.1.50.253;
}

Finally, set up NFS.  My /etc/exports looks like this:

/tftpboot       15.0.0.0/255.0.0.0(rw,no_root_squash)

Now my machine attempts to mount /tftpboot/15.1.50.253, so I have to
create a directory hierarchy there.

Tell all the daemons to reload their configuration files, and you should
be set.
