! 58: HP 9000/300-series workstations support network booting with
! 59: Boot ROM Revision B or later. (This includes any Boot ROM with a numeric
! 60: revision). The HP Boot ROM uses the
! 61: <b>HP Remote Maintainance Protocol</b> to download the boot code
! 62: from the server. The server must run a daemon capable of responding
! 63: 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>.

! 94: This is the output of one of a set of temporary, informational only,

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

! 175: From the <i>Configuration Reference Manual</i>, 98561-90020:
! 176: <p>
! 177: <cite><h3>Revision A Boot ROM Specifications</h3>
! 178: The boot ROM can load a ROM system or a file from a LIF or SRM
! 179: "SYSTEM" type file having a name of the form SYSa, where "a" is typically
! 180: an ASCII letter, but may be any character legal in a file name.
! 181: <p>
! 182: ROM systems are assigned a single letter ID (only "B", for BASIC, is
! 183: presently supported on Series 300).
! 184: <p>
! 185: All system files found are assigned an ID of the form "nna", where "a" is
! 186: either the same letter "a" mentioned above (if an ASCII letter), or "Z"
! 187: (if not an ASCII letter). "nn" is a number of the form " 1" to "99"
! 188: denoting the order of occurence of systems which result in the same ID
! 189: letter "a". The range of system IDs is " 1A" to "99Z".
! 190: <p>
! 191: The boot ROM loads the first system found unless characters (other than
! 192: that system's ID) are typed on the boot control keyboard (see below). The
! 193: search order used by the boot ROM is:
! 194: <p>
! 195: <ul><li>For select codes 7 thru 31: disc or tape (HPIB) at bus address 0,
! 196: unit 0, volume 0
! 197: <li>SRM at select code 21, node 0, volume 8, "/SYSTEMS" directory
! 198: <li>98259A Bubble system at select code 30
! 199: <li>98255 EPROM "disc"-type system at unit 0 (lowest address of all 98255s installed)
! 200: <li>ROM systems (from lowest to highest ROM address)
! 201: <li>For select codes 0 thru 31, bus addresses 0 to 7, units 0 to 16,
! 202: volumes 0 to 7: all remaining discs or tapes (HPIB)
! 203: <li>For select codes 0 thru 31, nodes 1 thru 62, volumes 1 to 50: any
! 204: other SRM system files in "/SYSTEMS" directories
! 205: <li>For select codes 0 thru 29, and 31: remaining 98255 Bubble systems
! 206: <li>Remaining 98255 "disc"-type EPROM units.
! 207: </ul></cite>
! 208: <p>
! 209:
! 210: Revision B and later also support booting over the network, using a 98643
! 211: card or built-in ethernet.
! 212: For older systems, the best choice is to make your boot drive on HPIB at
! 213: address 0. Remember, you'll need to capitalize the letters.
! 214: <p>
! 215: <h3>Newer Boot ROM Search Order</h3>
! 216: The newer machines (Models 345, 375, 380, 382, 385, and Series 400) have a
! 217: different boot order. From <i>HP Apollo 9000 Series 400 HP-UX Owner's
! 218: Guide</i>, A1630-90006:
! 219: <p>
! 220: <cite>The Scan for Systems selection searches mass storage devices for an

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

! 317: This step is necessary, since OpenBSD can only

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