+To set up your OpenBSD/hp300 workstation, follow the +diskless(8) man page. +
setenv TERM hp300h+Otherwise many things won't work, including vi. + +
+Anyone can +browse or download patches from HP's site without requiring a support +contract. (Not that any of this matters to OpenBSD/hp300 users of course) + +
+At any time after it recognizes the keyboard, while it is doing its self +test or searching for a +bootable system, you can hit reset to return it to a cold-boot +configuration. On HIL keybaords, this is +<control>-<shift>-break, +where 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 test or 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, 375, 380, 382, 385) is capable of a little bit more. +To select which device to boot from, press <return> once, +after it +beeps twice (i.e. recognizes the HIL keyboard). To get to a configuration +and test menu, press: +
+ C <return> ++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. +
+
+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 occurence 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:
+
+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.
+
+
+ +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. +
+
+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 |
| 1 | +SCSI | +0-31 | +7-5 | +0 |
| 2 | +HP-IB | +0-31 | +7-5 | +0 |
| 3 | +SRM | +14 | +N/A | +N/A |
| 4 | +LAN | +21 | +N/A | +N/A |
| 5 | +Bubble RAM | +30 | +N/A | +N/A |
| 6 | +EEPROM | +N/A | +N/A | +0 |
| 7 | +SCSI | +0-31 | +4-0 | +0 |
| 8 | +HP-IB | +0-31 | +4-0 | +0 |
| 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. +

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: + +

+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. + +

+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. + +

+This is the full procedure captured from +a serial console on my 400s. It may be slightly different for the 300 +series machines (345, 375, 380, 382, 385). +
+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 +R. +
+You may also temporarily override this setting by typing +L<return> or R<return> after +your system beeps twice and recognizes the keyboard. This will work even +if you have a Domain keyboard. + +
+Since the hardware takes care of this console, you do not add an +entry for the console in /etc/ttys. That would be bad. + +
