If anybody wants to take Genie/Lamp for a spin, you can get it here: Lamp Ain't Mac POSIX http://www.metamage.com/lamp/ Once running, /sys/mac/xpram is a read-only virtual file corresponding to the 256-byte XPRam. You can either hack it with perl or cat the whole thing into a real file and view it with HexEdit. Also, the 'drvr' script will iterate through /sys/mac/unit and list all the installed drivers. Bear in mind that at present I am Lamp's only user, so some gotchas are to be expected. Josh
