Changing to Serial Console

WARNING: Improper setting of the console path may cause the system to become inoperable. Beware.

Unfortunately, HP decided that the 712 should be hard to configure for headless use.

Briefly, you must get to the HP-UX bootloader prompt (which they call the ISL) which will allow you to permanently set your preferred console location to the first serial port at 9600 8N1.

The original source of this information is http://lists.parisc-linux.org/pipermail/parisc-linux/1999-December/008117.html.

To change to a serial console, you need:

  • a PS/2 style keyboard
  • a monitor with VGA style interface
  • the HP-UX ISL (either an HP-UX bootable hard drive or netboot)

First, you need to get to the BootROM prompt. When your system prints the following on screen, press and hold ESC until you get the BOOT_ADMIN> prompt:

Press <ESCAPE> to stop boot sequence.

Setting monitor type

If your display doesn't show properly, the frequency may be out-of-range. You can select the monitor type suitable to your display.

If your 712 has the add-in VRAM board, normal VGA 680x480 mode is monitor type 7. Without the VRAM board, the number may be different (possibly 5?).

BOOT_ADMIN> monitor 7

Setting console location

Run the following command to set your 712 to use a serial console:

ISL> conspath 2/0/4.0x283

To set your 712 to use the local console (i.e. keyboard and screen), run the following command:

ISL> conspath 1/0/0.0

You can use the display and information commands to verify that your settings have been stored properly. Once you're sure everything looks right, power cycle your workstation to start using your serial console.

Additionally, you can temporarily use the local console by pressing the “Esc” key on the PS/2 keyboard while resetting. This is setting only affects the console location temporarily and only works with firmware rev 1.6 and later.
