Well, looks like the problem is known, good! But we have a queer little
problem with our machines here, we are unable to boot from the network. I
think we did everything right, in fact, we are trying to use a server here
other machines boot from, it has dhcp, boopt, tftp, rarp, the works. We
set it all up, put the kernel on the tftpboot area, tested all that we
could by other means but, when we try to net boot the HPs, we are faced
with complete silence on the network. No logs on the server, nothing.

A little explanation might be needed: these are not really native 735-125
models, they were upgraded from older 720-50 models by card swapping. I am
not sure whether all cards were changed, maybe some aspects of the machine
are still old. The syntax of the net boot procedure in them is strange,
you have to put in the hardware address of the server, which is unusual.

I _suspect_ that this bios does not use tcp/ip for the net boot, but some
HP proprietary protocol relating to that clustering software they have or
used to have for these machines, in which you ran several stations out of
the disks of a single one. In any case, a listing of what happens on the
console on a net-boot trial goes below. We had a tail -f on the system log
of the server, we had tcpdump listening, but nothing at all shows up...

LAN (IEEE 802.3/Ethernet LAN) Path Specification

   lan.<server_address>.<init_retry>.<io_retry>

    <lan_server_address>      12 digit (hex) LAN server address 
    <init_retry>              max number of times to try a boot request
                               (0 = default, 255 = infinite)
    <io_retry>                max number of times to try a read request
                               (0 = default, 255 = infinite)

Example: to specify LAN address 123456-78ABCD with infinite
initialization retries and default I/O retries,

           lan.123456-78ABCD.255.0

If one or more parameters are not specified, the following
defaults will be used:    <lan_server_address> = 000000-000000 
                          <init_retry>   = 3 tries
                          <io_retry>     = 6 tries
