Updating OBP without Solaris
I've been playing over the last couple of days with booting Sun's Standalone Flash PROM Update Utility over the network using rarp and tftp, to good effect. As a general question, does anybody know whether the OS can check the state of the write protect/enable jumper (and/or front panel keyswitch as appropriate) for security purposes? -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

I'm not sure about the jumper, but there are experimental (out-of-kernel) drivers for SUNW,envctrl (E450) and SUNW,envctrltwo (E250) that are able to read the keyswitch position. Other platforms could likely be supported as well. Let me know if you are interested.

Thanks Eric, I've not got a 250 or 450 but am hoping to lay my hands on a 4500 as soon as we can get a van up to the seller. Otherwise the only machines I've got with keyswitches are 1000Es, and since those are like nothing else on Earth I doubt your code would apply :-) I'll be in touch once I've got the extra machine if it turns out to be a useful hacker platform. -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

lockdown?
Greetings! What machine can I use to investigate and hopefully fix a sparc-only bug in one of my packages?

Sun Ultra 10 for sale
I don't know if this is the proper place to list this or not but here goes. I work for a charity in Tucson, AZ called World Care. Part of what we do is refurbish computers. Right now I have 2 Sun U10s with 128 MB ram, IIi 300 MHz Processor and 4 GB IDE hard drive. They have Creator video cards (not 3D) each has a Sun SCSI card installed. I installed basic Debian on one and Basic netBSD on the other so I know the CDROM and hard drive works. If anyone is interested, we are asking $20 + shipping for them. As this is for charity, it is deductable. Please contact me at [EMAIL PROTECTED] Earl URL http://deserthowler.cjb.net Instant messenger: earlcoyote ICQ:64033496 __ Do You Yahoo!? Tired of spam?
