A couple of weeks ago, I posted a question I had about getting A/UX (or Finder) to recognize a Jasmine 50 as a 50Meg drive. I've done some legwork, and my answer should answer your question, also. I'm sorry if this turns out to be more than you want; I'm kind of answering two things at once. If anybody has useful information to add, or constructive criticism (e.g., "George, how utterly STUPID can you be? Why did you do that?!"), please post it or send me mail. My problem was that Finder couldn't format the DD50 as a 50Meg disk, and Jasmine's DriveWare isn't A/UX compatible (as of last Thursday, at least). But, when I did "dp" on the Jasmine, all 50 Meg showed up. The problem was that it showed up in two different partitions, named MacOS (type: Apple_HFS) Extra (type: Apple_Free) So I decided to try and make a different filesystem on each partition (actually, I tried to combine these two partitions into one, since they seemed to represent contiguous space. I strongly recommend you do *NOT* try this). Here's what I did: First, do all the stuff that the "A/UX Accessory Kit" docs tell you. They walk you through the "dp" process, telling you to change some fields on disk to make it an A/UX disk. I did this for both partitions, changing each to A/UX partitions, naming them "Lots_O_Storage" and "More_Storage". Be sure to save those changes by exiting "dp" with the "wq" command. Next I ran the 'pname' command, which announces to A/UX the new partition names I've created. I typed, for example: pname -c6 "Lots_O_Storage" which told A/UX that one of my newly-created partitions is on SCSI address 6. 'pname' gave that partition a slice number, which is used later. I did another pname command for "More_Storage". Next, I created the '/etc/ptab' file, so that every time I boot A/UX, the system would know about my partitions. I did that by typing pname -p >/etc/ptab (Oops! Please, *please* make sure you're root while you do all of this stuff.) If you just type "pname -p", that'll list the partitions that A/UX knows about, and their corresponding places on disk(s). After I did this, I went back to the A/UX Accessory Kit instructions, which told me to make a file system on each of my partitions, then run 'fsck' on them, run 'mklost+found', then make a mount point for each partition, mount them on the system, and edit my 'etc/fstab' file to tell A/UX what partitions were mounted as what directories. That's the short of it. The key here was to use "pname" to set information about how the disk was partitioned. If you have any questions about what I wrote, send me mail or post a message. I just hacked at it as long as I could, since I could find nobody who's done this before. If anybody has had similar experiences, please let me know. If you have a better way of doing this, I'd like to know that, too. I hope this helped some. ______________________________________________________________________________ George D.
