According A/UX Essentials a Mac/OS HardDisk should mount on the desktop under AU/X 2.0, but mine doesn't. I tried a CMS 300 (Wren V) and a PLI removable (Syquest). Both show up when I start the Mac (II fx with 80 Mb internal drive), but when I start up AU/X 2.0, they disappear. Any clues??? Please respond by email! Thanks!

Please respond by email! Thanks! Paul For MacOS hard disks, or to be more precise, partitions of hard disks to show up under A/UX, a number of rules must be satisfied: 1) The disk in question must be using the "new" style partition map defined first in IM IV. 2) It must contain at least one MacOS partition and this must be referred to from the very first entry in the partition map. 3) The partition type must be "Apple_HFS". Point 2 above is an Apple screw up. I accept (to a certain extent) that Apple's Mac disk driver under A/UX can handle only one MacOS volume per SCSI id, but is documented nowhere that this should be in the very first partition map entry. This is just plain stupid. Apple seems to know about it, because HD Setup is handling the situation correctly, as is the software I wrote myself. Most SCSI software that does not allow you to put A/UX partitions on a disk will not do this anyway. This (I think) is the case for CMS software and PLI software. For information on SCSI-Power, one of the very best package around for dealing with disk partitioning, send me an e-mail. It does handle your problem, supports SyQuest (and much better than most everybody else when you insert "foreign" cartridges formatted by another brand of software) and allows A/UX partitioning. --dolf -- Dolf Starreveld Phone: +31 20 592 5056/5022 (FAX: 5155), TELEX: 10262 HEF NL EMAIL: dolf@fwi.uva.nl (dolf%fwi.uva.nl@hp4nl.nluug.nl) SNAIL: Dept. of Math. and Computing Science, University of Amsterdam, Kruislaan 409, NL-1098 SJ Amsterdam, The Netherlands

[...] Sorry, but wrong. I have here a hard disk which mounts just fine, and which has the following partitions (in this order): - Partition Map - Driver - A/UX 1 - A/UX 2 - HFS and it mounts just fine. < For information on SCSI-Power, one of the very best package around for dealing < with disk partitioning, send me an e-mail.

The "partition maps" which some installers create are just plain stupid. (Padding the map entries with spaces instead of zeroes, preposterous logical sizes and flags, you name it...) -- Matthias Urlichs -- urlichs@smurf.sub.org -- urlichs@smurf.ira.uka.de /(o\ Humboldtstrasse 7 - 7500 Karlsruhe 1 - FRG -- +49+721+621127(0700-2330) \o)/
