Actually, when trying to use escher, I get the error message "/dev/dsk/c6d0s9 previously pnamed" There is no such slice nor device. I have slices up to c6d0s8, with slices 7 and 8 being eschatology systems. You have assigned slice numbers for Eschatology file systems? Neither HD Setup nor LaCie's SilverLining does this... I created the partitions using dp, so I'm not sure wether they are real OK... (They work, tho, swap & root & usr & the rest) (The output of command "P" of "dp /dev/dsk/c6d0s31" would have come in handy here ;) Here's a "short" walk-through of the "Eschatology" file system on a "standard" A/UX disk, partitioned by Apple's HD Setup. Will this help you at all? As always, your mileage may vary... $ pname -p <- show the current, recognized Root file system:Apple_UNIX_SVR2:0:0:0 partitions Swap:Apple_UNIX_SVR2:0:0:1 Usr file system:Apple_UNIX_SVR2:0:0:2 :Apple_HFS:0:0:30 $ dp /dev/dsk/c0d0s31 Command?

If it matters for escher, I don't know... Suggestions? Scrap the slice-#:s for the Eschatology partitions, and create a new (SysV?) file system on the partitions. Due caution is adviced :) as this may totally mess up your existing set up. Regards, Chape -- "Imagine there's no Windows, It's easy if you try..." Steven Levy, Macworld April '91
