    7: # Using a serial console<a name="serial_console"></a>
    9: On most models, you can configure the Boot ROM to use a serial console
   10: instead of a locally attached keyboard and the framebuffer. The serial
   11: console will typically run at 9600 bps, 8 N 1 on Port "A" or "1". The
   12: procedure varies between models, but you *will* need a keyboard and
   13: monitor connected initially to configure the Boot ROM. The procedure is
   14: described below.
   16: There are some tricks you can play to force a serial console without
   17: initially connecting a keyboard and monitor. For models with removable
   18: framebuffers (such as the 720, 730, 735, and 755), simply remove the SGC
   19: framebuffer and the system will default to serial console. Apparently,
   20: [powering up with the keyboard
   21: disconnected](
   22: and [holding down the TOC (Transfer of Control) button on the side of
   23: the machine for 10 seconds while powering
   24: up](
   25: will force a serial console. The last two tricks do not appear to work
   26: on older models (such as the 715 and 735). See the [special
   27: instructions]( for model 712 workstations.

   33: <ol>
   34: <li>Turn the PA-RISC machine on. Have both the keyboard and mouse connected.</li>
   35: <li>During the boot process, the following message will appear:
   36: <pre class="programlisting">
   37: Searching for Potential Boot Devices.
   38: To terminate search, press and hold the ESCAPE key.
   39: </pre>
   40: When this message appears, press and hold the Esc key until an
   41: options menu appears.</li>
   42: <li>By default, you enter the `BOOT_ADMIN` console. In some 715s,
   43: the options menu looks like this:
   44: <pre class="programlisting">
   45: b)    Boot from specified device
   46: s)    Search for bootable devices
   47: a)    Enter Boot Administration mode
   48: x)    Exit and continue boot sequence
   49: ?)    Help<br />
   50:        Select from menu:
   51: </pre>
   52: Select `a) Enter Boot Administration mode`. This will bring
   53: up a `BOOT_ADMIN>` prompt. Everything else you do will be in
   54: `BOOT_ADMIN` mode. So now, everybody is in the
   55: `BOOT_ADMIN` console!</li>
   57: <li>To change to serial console mode, type the following command at the
   58: `BOOT_ADMIN` command prompt:
   59: <pre class="programlisting">
   60: path console rs232_a.9600.8.none
   61: </pre>
   62: </li>
   63: <li>Power down, power up. Be ready to hit ESC on your terminal to break
   64:     into the same options menu as in step 3.</li>
   65: </ol>
   67: # How do I configure power-on settings (boot device, console, etc.)
   69: All 700 series workstations have a Boot Administration command line
   70: utility in their Boot ROM which lets you configure various settings. For
   71: example, you can set whether the system automatically boots an OS, which
   72: device to try booting from first, determine the ethernet MAC address,
   73: set up a serial console, and possibly do some low level hardware access.
   75: To get to the `BOOT_ADMIN` prompt, you must press the
   76: `ESCAPE` key before it tries to boot an OS. Since these machines
   77: often take a long time between powering on and the brief window of time
   78: where you can hit the `ESCAPE` key, you must pay attention. It
   79: may take over a minute after pressing the power button before anything
   80: will show up on screen.
   82: Once you have escaped out of the `Selecting a system to boot` and
   83: `Searching for Potential Boot Devices` you need to type the
   84: "`a`" key to get to the `BOOT_ADMIN` prompt. Now, use the
   85: online help with the `HELP` command.
   87: Have fun (and see this brief [[transcript|boot_admin]] of some of the `BOOT_ADMIN` menus options on a 735/99).
   89: # What devices does my system try to boot from (and how do I change it)
   91: Use the `AUTOSELECT` and `PATH` commands in the
   92: [`BOOT_ADMIN`](#boot_admin) environment.
   94: # History of NetBSD/hppa
   96: The hp700 port of NetBSD was started by Matt Fredette in October 2001. He started working with Michael Shalayeff's [OpenBSD/hppa]( sources at that time, and after much work had it booting multiuser in March of 2002. At that time he began merging the port into the NetBSD tree.
   98: The port was renamed NetBSD/hppa for the 7.0 release.
