I have a 100 meg external Jasmine drive with three partitions, one for the Mac OS, one for MS-DOS (unfortunate, but necessary...), and a third which I'd like to use with A/UX. How in the world do I get A/UX to recognize that partition? The documentation suggests that I should start with dp, but the drive is already partitionned. Has anybody out there done this? Would you be so kind as to share the trick with me?

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.

I believe that currently AUX 1.0 supports only one large capacity drive: the CDC-Wren III (150 megs.) The 100 meg Jasimine may not cut it, since it does not appear to contain the above unit. You may have to wait for the next AUX upgrade. nghiem@walt.cc.utexas.edu

The SCSI driver was designed with that in mind. (Note that their may be some problems if the drive doesn't come preformatted and you don't have a mac program to do that, the diskformat command doesn't deal well with any thing but floppies.) My suggestion on how to add a generic drive with mac and A/UX partitions would be: 1) Use the software that came with the drive to format it. 2) Use "Apple HD SC Setup" to partition the drive, this is the preferable method since it draws nice pictures and let's you drag to set partition sizes. Unfortunately it only works with a limited set of drives, basically, those which might find their way into an Apple marked product. (Q280S, Rodime 20, 40, 80, etc.) You want to select a "custom" partition, you can then split the drive up however you want between mac and unix. 3) If you have a drive that won't work with HD SC Setup, you get to use dp to change the partition map on the drive. Shrink the physical and logical sizes of the mac partition as desired and then add the A/UX partition. 4) Use mkfs to make the required filesystem. Note that if you allowed the default partition type in 3) than your drive will automatically be assigned to /dev/dsk/c{scsiid}d0s{slice} where slice is either 0 for "root" partitions or 2 for "user" partitions. 5) Go back to the macintosh operating system and select "Erase Drive" on the disk. Otherwise you'll have all kinds of problems since the file system size doesn't match the partition size. It's quite a bit simpler if you just want to use the drive as an A/UX drive since you just format the drive and use dp to create a partition map. > >nghiem@walt.cc.utexas.edu Opinions: MINE, ALL MINE!
