| |
HP 9000/300-series workstations support network booting with |
| |
Boot ROM Revision B or later. (This includes any Boot ROM with a numeric |
| |
revision). The HP Boot ROM uses the |
| |
<b>HP Remote Maintainance Protocol</b> to download the boot code |
| |
from the server. The server must run a daemon capable of responding |
| |
to HP RMP boot requests, <i><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=rbootd&apropos=0&sektion=0&manpath=OpenBSD+Current&format=html">rbootd(8)</a></i>. |

If you're using a local console, and you're running csh or tcsh, you'll |

We currently have all X11R6 clients, with an X11R5 server. |

The standard OpenBSD distribution includes an old BSD 4.4 Xserver which is |

This is the output of one of a set of temporary, informational only, |
| |
exception handlers installed by the Boot ROM before an OS has been loaded. |
| |
The address printed varies depending on the type of exception. |
| |
The most likely cause here is trying to boot a kernel that is incompatible |
| |
with the hardware. You will get something like this, for example, if you |
| |
attempt to boot an HP-UX 7.0 or earlier kernel on a 68040 machine |
| |
(which requires at least 7.05). If you're going to install OpenBSD, you |
| |
probably don't need to worry about this message, though it is possible (but |
| |
unlikely) that it indicates hardware trouble or a corrupt bootloader. |

</dt><dd> |
| |
All the early hp300 Boot ROMs are very primitive and only allow a few |
| |
simple operations. You can only interact with it after it is first |
| |
powered on -- if you reboot the machine, it will ignore anything you type |
| |
and start loading the same OS you previously booted. |
| |
<p> |
| |
At any time after it recognizes the keyboard, while it is doing its self |
| |
test or searching for a |
| |
bootable system, you can hit <tt>reset</tt> to return it to a cold-boot |
| |
configuration. On HIL keybaords, this is |
| |
<tt><control>-<shift>-break</tt>, |
| |
where <tt>break</tt> is the key in the upper left (where escape is on sane |
| |
keyboards). There is no equivalent over serial terminal -- you'll need to |
| |
power-cycle your machine. |
| |
<p> |
| |
After it beeps (i.e. recognizes the HIL keyboard), press |
| |
<tt><return></tt> twice to get the list of bootable devices. |
| |
To perform simple hardware checks, hit <tt><control>-C</tt> before |
| |
it starts booting an OS. You can then type <tt>T</tt> to perform an |
| |
extended self test or <tt>L</tt> to perform the extended self test |
| |
infinitely until it finds a fatal error or <tt>L</tt> is typed again. |
| |
<p> |
| |
The newer HP Boot ROM, present on Series 400 machines and some of |
| |
the later 300s (345, 375, 380, 382, 385) is capable of a little bit more. |
| |
To select which device to boot from, press <tt><return></tt> once, |
| |
after it |
| |
beeps twice (i.e. recognizes the HIL keyboard). To get to a configuration |
| |
and test menu, press: |
| |
<pre> |
| |
C <return> |
| |
</pre> |
| |
This will allow you to configure interrupt levels, select codes, and |
| |
serial console properties. You can also hit <tt><control>-C</tt> to |
| |
get to a menu of extended tests with several fancy options. |

</dt><dd> |
| |
From the <i>Configuration Reference Manual</i>, 98561-90020: |
| |
<p> |
| |
<cite><h3>Revision A Boot ROM Specifications</h3> |
| |
The boot ROM can load a ROM system or a file from a LIF or SRM |
| |
"SYSTEM" type file having a name of the form SYSa, where "a" is typically |
| |
an ASCII letter, but may be any character legal in a file name. |
| |
<p> |
| |
ROM systems are assigned a single letter ID (only "B", for BASIC, is |
| |
presently supported on Series 300). |
| |
<p> |
| |
All system files found are assigned an ID of the form "nna", where "a" is |
| |
either the same letter "a" mentioned above (if an ASCII letter), or "Z" |
| |
(if not an ASCII letter). "nn" is a number of the form " 1" to "99" |
| |
denoting the order of occurence of systems which result in the same ID |
| |
letter "a". The range of system IDs is " 1A" to "99Z". |
| |
<p> |
| |
The boot ROM loads the first system found unless characters (other than |
| |
that system's ID) are typed on the boot control keyboard (see below). The |
| |
search order used by the boot ROM is: |
| |
<p> |
| |
<ul><li>For select codes 7 thru 31: disc or tape (HPIB) at bus address 0, |
| |
unit 0, volume 0 |
| |
<li>SRM at select code 21, node 0, volume 8, "/SYSTEMS" directory |
| |
<li>98259A Bubble system at select code 30 |
| |
<li>98255 EPROM "disc"-type system at unit 0 (lowest address of all 98255s installed) |
| |
<li>ROM systems (from lowest to highest ROM address) |
| |
<li>For select codes 0 thru 31, bus addresses 0 to 7, units 0 to 16, |
| |
volumes 0 to 7: all remaining discs or tapes (HPIB) |
| |
<li>For select codes 0 thru 31, nodes 1 thru 62, volumes 1 to 50: any |
| |
other SRM system files in "/SYSTEMS" directories |
| |
<li>For select codes 0 thru 29, and 31: remaining 98255 Bubble systems |
| |
<li>Remaining 98255 "disc"-type EPROM units. |
| |
</ul></cite> |
| |
<p> |
| |
|
| |
Revision B and later also support booting over the network, using a 98643 |
| |
card or built-in ethernet. |
| |
For older systems, the best choice is to make your boot drive on HPIB at |
| |
address 0. Remember, you'll need to capitalize the letters. |
| |
<p> |
| |
<h3>Newer Boot ROM Search Order</h3> |
| |
The newer machines (Models 345, 375, 380, 382, 385, and Series 400) have a |
| |
different boot order. From <i>HP Apollo 9000 Series 400 HP-UX Owner's |
| |
Guide</i>, A1630-90006: |
| |
<p> |
| |
<cite>The Scan for Systems selection searches mass storage devices for an |
| |
operating system to boot. The first mass storage device found with an |
| |
HP-UX Compatible operating system on it boots. Mass storage devices are |
| |
searched by the priority shown in this table.</cite> |

So, for these newer systems, your best bet is to make your boot drive a |
| |
SCSI drive at address 6 (7 is the system controller on the motherboard). |
| |
<p> |
| |
It is also possible to configure the Boot ROM to default to a specific |
| |
device from the configuration menu. |

| |
This step is necessary, since OpenBSD can only |
| |
boot a Series 400 machine when it's set up in "HP-UX Compatible Boot |
| |
Mode". If, when you power on your machine, it does <b>not</b> present a |
| |
menu as follows, then you need to follow the instructions below: |

[...]</pre> |
| |
|
| |
First, you'll need either a Domain keyboard or a HIL keyboard (the Boot |
| |
ROM knows how to use either, even if OpenBSD doesn't yet). |
| |
Now, put your machine into "service mode". For a 4XXs, there's a toggle |
| |
switch on the back of the machine (near the top). For a 4XXt or 4XXdl, |
| |
there's a green button on the front, behind the silly door. For a 425e, |
| |
there's a toggle switch on the back of the machine (in the middle). |
| |
Once you're in "service mode", the other |
| |
green LED will light up. Reset the machine. You may then need to hit |
| |
return to get the Domain boot prompt. At that prompt, you can type |
| |
<tt><b>H</b></tt> to get a list of available commands. You need to type |
| |
the following things to convert to HP-UX mode: |

| |
<a href="domain.commands.html">This</a> is the full procedure captured |
| |
from a serial console. |
| |
<p> |
| |
Be sure to turn <b>off</b> "service mode" when you're done. I found it |
| |
prevented me from selecting which device I wanted to boot from. |

Turn off power to your system before removing any cards. Remove the |

Locate the bank of 4 DIP switches<br> |
| Press the <i>service</i> switch on the front panel; the LED will light, |
One of them should be labeled REM<br> |
| then press the <i>reset</i> switch on the back of the machine. |
Set the switch to ?<br> |
| The system should then boot into <b>MD</b> mode, and display a <b>></b> |

| times; when the prompt appears, type <b>hp</b> and press <i>return</i>. |
The third switch is labeled REM<br> |
| Your system should then reset and display the HP-UX style ROM messages. |
Set the switch to one (depress the end labeled one)<br> |
| <li>How do I change the hp400 boot ROM mode from HP-UX to Domain/OS? |

<p><li><b><tt>98626</tt></b> (dca)<br> |
| <li>How do I set the serial port to be the console on a 300-series machine? |
Locate the jumper by the two banks of DIP switches<br> |

The last switch (labeled 7) is the remote switch<br> |

Set the switch to zero (depress the end labeled zero) |
| <i>return</i>. The configuration menu will appear, from where you can |
<p><li><b><tt>98642</tt></b> (dcm)<br> |
| put the serial port into <b>remote</b> mode. |
Locate the 8 DIP switches<br> |
| |
The first switch (labeled 1) is the remote switch<br> |
| |
Set the switch to one (slide the bump to one)<br> |
| |
<i>Note: According to the manual, the Boot ROM on older machines |
| |
does not know how to use this for console, but OpenBSD (and HP-UX) |
| |
will, so you won't see anything until the bootloader loads.</i> |
| |
<p><li><b><tt>98644</tt></b> (dca)<br> |
| |
Locate the 10 DIP switches<br> |
| |
The last switch (labeled 1) is the remote switch<br> |
| |
Set the switch to one (depress the end labeled one)<br> |
| </ul> |
</ul> |
| </p> |

| |
Now, reinsert the card and power on your machine. All console messages |
| |
will be sent over the serial port at |
| |
9600 bps, 8 bits, no parity, 1 stop bit. Theoretically, you should be |
| |
using a null-modem cable, but I found that for my 98562, I needed a |
| |
non-null modem cable. |

Wait until your system beeps twice (this is to let |
| |
you know it's |
| |
recognized the keyboard). Type <tt><b>C<return></b></tt> and wait |

until the configuration menu shows up. Then type in the following set of |

Now, your machine will reset and then send all console messages over the |

serial port at |

9600 bps, 8 bits, no parity, 1 stop bit. Use a null-modem cable. |

<p> |

If you want to convert from serial console to monitor/keyboard console, |

follow the same procedure, except type <tt><b>L</b></tt> instead of |
| |
<tt><b>R</b></tt>. |

<p> |
| |
You may also <i>temporarily</i> override this setting by typing |
| |
<tt><b>L<return></b></tt> or <tt><b>R<return></b></tt> after |
| |
your system beeps twice and recognizes the keyboard. This will work even |
| |
if you have a Domain keyboard. |
| |
|
| |
<p> |
| |
Since the hardware takes care of this console, you do <b>not</b> add an |
| |
entry for the console in <tt>/etc/ttys</tt>. That would be bad. |

Build the funky <a href="serial.splitter.html">cable</a>. Otherwise, just |

using a normal DB25 serial cable will work fine if you only want one |
