This means your framebuffer is not supported. Hook up a serial terminal, 9600 bps, 8 bits, no parity, 1 stop bit, xon/xoff flow control.
Contact port-hp300@NetBSD.org if you'd like to work on writing a driver for your framebuffer.
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 HP Remote Maintainance Protocol to download the boot code from the server. The server must run a daemon capable of responding to HP RMP boot requests. If your server runs NetBSD, it has rbootd(8) in the base system. If your server runs another OS, like Linux or Solaris, you can try YAMAMORI Takenori's sun-rbootd package.
Series 400 machines have two Ethernet media types built into the motherboard. You may only use one at a time. When your Series 400 workstation goes through the self-test when powered on or rebooted, it will say one of the following:
HP98643 (LAN) at 21, AUI HP98643 (LAN) at 21, Thin
If the wrong type of network is selected, you will need to change the Ethernet port. You will need to open the case (4XXt, 4XXdl, 4XXe) or remove the motherboard (4XXs) to access the jumper. Be sure to use static-prevention measures, as you could easily fry your motherboard from carelessness. If you are uncomfortable with this, ask a friend who is aware of these issues. There is a block of 8 jumpers at the rear of the motherboard, labeled AUI/Thin. You will need to put the jumpers in the position necessary for your type of Ethernet.
If you're using a local console on NetBSD 5.x or prior, and you're running csh or tcsh, you'll need to make sure you run:
setenv TERM hp300h
Otherwise many things won't work, including vi.
On NetBSD -current with wscons support (including future 6.0 and later
TERM environment variable as
other wscons ports.
NetBSD 5.x includes all X11R6 clients, but there is no functional server.
NetBSD 6.0 (and later releases) will have Xorg server based on generic wsfb driver.
The SCSI cable in these models is not notched to specify which way it should be plugged in. The symptom is being unable to boot due to a SCSI register test failing. If you are certain that your hard drive works properly on another machine, then flip one end of the SCSI cable over.
The only other models that accept internal hard drives are the 362, 382, 4XXt, and 4XXs which do not have this uncertainty in cabling.
These models were designed as instrument controllers, unlike the rest of the Series 300 and Series 400 systems which were intended as workstations or servers. The 362 and 382 are 19" rackmount units with very PC-like properties.
They have 72 pin SIMM slots (with parity on 362, with ECC on 382), two SCSI drive bays (usually HD and SCSI floppy), serial, parallel (not currently supported by NetBSD), HPIB, sound, HP-HIL, one DIO-I slot, and a VGA-style video connector. The 362 has 2 SIMM slots and you can install SIMMs one at a time. The 382 has 4 SIMM slots and you must install in pairs. Both models accept only 1, 4, and 8 MB SIMMs.
382 has three serial ports using the Utility Chip like the Series 400 models. Only one is accessible unless you build or buy the special cable.
362 has only 640x480 8bpp VGA like graphics chip. 382 was shipped with three different graphics chipsets (all 8 bpp): 640x480 at 60 Hz, 1024x768 at 75 Hz, and 1280x1024 at 72 Hz. These on-board graphics are not supported by NetBSD 5.x and prior, but you can install a DIO-I framebuffer and disable the on-board video (there's a jumper on the motherboard).
Since the system was designed as a controller, Ethernet and external SCSI are optional and are in the form of a small card that plugs into the motherboard. The card is roughly the size of two PCMCIA cards stacked together. You can, of course, use a DIO-I Ethernet card.
Oddly, the motherboard is the same shape and size as a DIO-II card and has DIO-II connectors. Jarkko Teppo reports that you can even put the motherboard into a normal DIO-II chassis and use it as a "normal" Series 300 system. The only problem he encountered was the physical size of the Ethernet option. See Jarkko Teppo's report for more info.
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 NetBSD, 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.
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.
At any time after it recognizes the keyboard, while it is doing its self
test or searching for a bootable system, you can hit
return it to a cold-boot configuration. On HIL keyboards, this is
break 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.
After it beeps (i.e. recognizes the HIL keyboard), press
<return> twice to get the list of bootable devices. To perform
simple hardware checks, hit
<control>-C before it starts
booting an OS. You can then type
T to perform an extended self
L to perform the extended self test infinitely until it
finds a fatal error or
L is typed again.
The newer HP Boot ROM, present on Series 400 machines and some of the
later 300s (345, 362, 375, 380, 382, 385) is capable of a little bit
more. To select which device to boot from, press
after it beeps twice (i.e. recognizes the HIL keyboard). To get to a
configuration and test menu, press:
This will allow you to configure interrupt levels, select codes, and
serial console properties. You can also hit
<control>-C to get
to a menu of extended tests with several fancy options.
For more information, Michael Wolfson has scanned in parts of the HP Apollo 9000 Series 400 HP-UX Owner's Guide, which has some good information on this topic. Also, the HP Computer Museum has various useful manuals and informations for many HP 9000 models.
From the Configuration Reference Manual, 98561-90020:
Revision A Boot ROM Specifications
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.
ROM systems are assigned a single letter ID (only "B", for BASIC, is presently supported on Series 300).
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 occurrence of systems which result in the same ID letter "a". The range of system IDs is " 1A" to "99Z".
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:
For select codes 7 thru 31: disc or tape (HPIB) at bus address 0, unit 0, volume 0
SRM at select code 21, node 0, volume 8, "/SYSTEMS" directory
98259A Bubble system at select code 30
98255 EPROM "disc"-type system at unit 0 (lowest address of all 98255s installed)
ROM systems (from lowest to highest ROM address)
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)
For select codes 0 thru 31, nodes 1 thru 62, volumes 1 to 50: any other SRM system files in "/SYSTEMS" directories
For select codes 0 thru 29, and 31: remaining 98255 Bubble systems
Remaining 98255 "disc"-type EPROM units.
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.
Newer Boot ROM Search Order
The newer machines (Models 345, 362, 375, 380, 382, 385, and Series 400) have a different boot order. From HP Apollo 9000 Series 400 HP-UX Owner's Guide, A1630-90006:
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.
|Priority Level||Device||Select Code||Bus Address||Unit Number|
|9||SRM||Other than 14||N/A||N/A|
|10||LAN||Other than 21||N/A||N/A|
|11||Bubble RAM||Other than 30||N/A||N/A|
|12||EEPROM||Other than 0||N/A||0|
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).
It is also possible to configure the Boot ROM to default to a specific device from the configuration menu.
This step is necessary, since NetBSD 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 not present a menu as follows, then you need to follow the instructions below:
Copyright 1990, Hewlett-Packard Company. All Rights Reserved. BOOTROM Series 400 Rev. 1.1 MD12 REV 1.2 1990/08/07.14:27:08 MC68030 Processor MC68882 Coprocessor Configuration EEPROM Utility Chip at 41 HP-HIL.Keyboard [...]
First, you'll need either a Domain keyboard or a HIL keyboard (the Boot
ROM knows how to use either, even if NetBSD 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
H to get a list of available commands. You
need to type the following things to convert to HP-UX mode:
CF 2 2 P E
is the full procedure captured from a serial console.
Be sure to turn off "service mode" when you're done. I found it prevented me from selecting which device I wanted to boot from.
Michael Wolfson has images of the HP 425/433 Boot ROM in HP-UX mode. This is necessary when upgrading a 400 to a 425/433
See The fatmac HP9000/300 guide for instructions on upgrading.
NetBSD -current has switched to using the
driver for dca and
apci devices. This
covers all built-in serial ports and some DIO serial interfaces. With
this change, the device files have changed. All DCA and APCI serial
/dev/ttyC and all DCM serial ports are
The APCI device (found on-board Series 400 systems) is a four-port serial mux interface. The first port connects directly with the Domain keyboard. The second port is accessible using normal DB25 pinouts and acts as the serial console (when set). The remaining two ports require use of a break-out cable.
Additionally, see the NetBSD Serial Port Primer for information on the wiring and pinouts of various serial cables.

Turn off power to your system before removing any cards. Remove the card with the serial interface.

Locate the 8 DIP switches, The first switch (labeled 1) is the remote switch, Set the switch to one (slide the bump to one). Note: According to the manual, the Boot ROM on older machines does not know how to use this for console, but NetBSD (and HP-UX) will, so you won't see anything until the bootloader loads.
Locate the 10 DIP switches, The last switch (labeled 1) is the remote switch. Set the switch to one (depress the end labeled one)
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.
Turn off power to your system. There are four DIP switches visible through the rear panel, flip the third switch from the left to one. Turn on your system.
Now, all console messages will be sent over the serial port at 9600 bps, 8 bits, no parity, 1 stop bit.
This procedure does not work on the 425e, since it does not support serial console in the Boot ROM.
Wait until your system beeps twice (this is to let you know it's
recognized the keyboard). Type
C<return> and wait until the
configuration menu shows up. Then type in the following set of commands:

The number you type for selecting the serial settings in the menu might be different on 362 or 382 models without the optional Ethernet.
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.
If you want to convert from serial console to monitor/keyboard console,
follow the same procedure, except type
L instead of

Since the hardware takes care of this console, you do not add an

/etc/ttys. That would be bad.
Build the funky. Otherwise, just using a normal DB25 serial cable will work fine if you only want one serial port.
Yes. A normal DB9<->DB25 adaptor will not work. This cable is HP part number.
