How to get into ISL on HP-UX 9.10, Apollo series 400

[Igor Streharski]

Hello all,

I have this subtle problem, when there's no getty running on a machine, yet I see no way to boot it into the single-user mode.
The box is an ancient Apollo series 400 workstation, the operating environment is HP-UX 9.10, fully patched.
Browsing through the users's manual, I've found how to choose a different kernel, how to choose between Domain and HP-UX, but what I really need is to have the ability to do something that we all do on s700/800 - to get into ISL and issue "hpux -is"...

How can I obtain this functionality?
Does that tiny switch (service/normal) on the rear panel have to do anything with it?

Any help will be appreciated!
TIA,

[Dan Hetzel]

Hi Igor,

I'm not sure for the Apollo, but usually the Service/Normal switch or key allows your system to react to when in 'service' position.

Hi !

In series 700 on boot time You can press when You see this message on the screen to BOOT_ADMIN level. May be when You see activating your display. You have only 10 sec, some monitor not enought for screen.
The BOT_ADMIN level is different but somwnere write:
boot pri isl

Try please.

regards, Saa

The apollo, rather HP workstations do not have a service switch,so ^B won't work.I go with the second reply.Press ESC key during bootup and at the BOOT ADMIN> prompt type "boot pri isl"

Good luck

Press "ESC" at the power on so that it comes to IPL.. at IPL type "bo pri isl" command.

This should take you to ISL prompt.
