Unknown root password on a SGI Indigo

[Deborah Grierson]

Sorry guys, this is not about HP kit, but I came to the fountain of ALL knowledge.

I have inherited two SGI Indigos for which I do not have the root passwords.

How can I get round this problem? I've had some vague advice that the boot process can be interrupted and ....... ?

HI John

I found this:-

There are 2 passwords that may be present on an Indigo: the root password, and the hardware PROM password. If you don't know either of these, then I'd advise you to give up now! The PROM password will allow you to boot off the CD-ROM and delete/reset the root password. Similarly, a root password will allow you to alter the PROM password (using the nvram command). On Indigo2s and Indys there's a jumper on one of the boards that allows you to reset the PROM password, but sadly the only way to do this on an Indigo involves a soldering iron! If the machine doesn't have the PROM password set, then that's even better... if you're thinking of buying one of these, check that you can get into the PROM before parting with cash (hold down Esc during power on for a menu).
