Hello again, I've remembered another problem with PROM passwords. I have sometimes seen Sun workstations sitting complacently with the line: "Boot:" It's expecting a device & file combination (I'm unsure of the exact syntax) to aid it to find somewhere to boot from. These machines are diskless and so boot from a remote server. They have a prom password and so the above prompt should ideally never be given. I imagine the cases where I've seen this are due to the machine running bootparams is down. I expect such things may be simulated by simply unplugging from the ethernet at critical times. James
