I haven't forgotten about you. I have the "official" digital documentation sitting at home that describes in great detail as to what each of those numbers means. I will reference that and see what it exactly means and get back to you. I don't want to lead you down the wrong path, but here is my initial guess: Your device pka0.7.1001.0 is a SCSI card on the first bus, SCSI ID 7. You may have to play around with it, but if you 'sho pka*' SRM will sho your settings of that SCSI card on your system. From there, you can modify the host id, the SCSI mode, and you can enable/disable soft-termination. The same holds true with network cards. I know here, my network guys force all servers to 100/Full. If I 'sho ewa*' I get a ton of options to set on the network card, I just play with the duplexing settings rather then play around with ifconfig. BSD takes what the SRM gives it as far as network card settings. About the password, 'ls' on your SRM, are there any commands in there similar to 'clear_nvram' or 'clear_srm_rom' or 'clear_arc'? I seem to remember seeing that on a Alpha box that I was playing around with. Here is what I can remember off the top of my head about SRM devices: dkaX - SCSI disk devices on the first bus, other disks on secondary busses are dkbX, dkcX, dkdX, etc. dqaX - IDE device on the first bus, other busses are dqbX, dqcX, etc. dvaX - Floppy ewaX - NIC, other NICs are ewbX, ewcX, etc. pkaX - SCSI card on the first SCSI bus. Other busses are pkbX, pkcX, etc. pqaX - First IDE controller, other controllers are pqbX, pqcX, etc. mkaX - Tape drive Good luck.

You seem to know a bit on SRMs disk capabilities. Is it possible for you (or someone else on the list) to explain the following device path: pka0.7.0.1001.0 ? It's configured in an AS600 for which the SRM console password is not available. Every atempt to clear that password has been failed. I already thought about unsoldering the NVRAM. -- B.Walter COSMO-Project http://www.cosmo-project.de ticso@cicely.de Usergroup info@cosmo-project.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
