There is an rboot daemon that comes with all the BSDs and I believe the
same daemon will work on Linux as well.  There were some endian problems
once, but I think they were all solved so it should work on x86 boxes.
It requires BPF.

I fixed up rbootd to run on Linux awhile ago... you should be able to
find it on ftp://puffin.external.hp.com.

This reminds me, does anyone have a working rbootd which runs on anything
other than HP-UX?  If we turn all our HPs into Linux boxes it would be nice to
still be able to boot them.  Of course looking at the rboot packets on the wire
shows that they are not anything I recognise...

[parisc-linux] Booting the kernel

[Davin Petersen]

After downloading the goodies available from the FTP site I gather that
rbootd is the way to spit the linux kernel to a HP box.  Am I wrong?  Is
there no way of using the ISL?  I tried using the ISL (on my H60), got
an error message and was dumped back to the ISL prompt.

rbootd is the way for older machines like my 715.  Later models like
the A180 tftp their kernel, I think you need bootparamd set up as well.

for the A180 you need a proper setup bootpd/tftpd combo.

That's not 100% correct, since my 715/64 uses bootpd/tftpd too.
David, you may start tftpd -d 0 (=zero) in etc/inetd.conf, so you can see
warnings & transfers on the Log-Console.

tftp    dgram   udp     wait    nobody  /usr/sbin/tcpd  in.tftpd /tftpboot

just for the record:
boot via rbootd
	715/33/50/75
	735/99/125

boot via bootptab
	715/64/80/100 ..
	712/60/80/100 

not at all
	B1000 (just a joke)

At the time the G/H/I series machines were released HP didn't support
network booting any 800 series machines, just workstations (700s).  I
suspect you won't be able to boot this machine from the network.
