My neighbor's MacII CX with A/UX and two 80 meg drives just arrived. Unfortunately, the documentation hasn't. What he wants to do is configure the external drive entirely A/UX, and split the internal into half MacOS, half A/UX. But I can't get A/UX to recognize the partitioned internal drive. What I did: Build a ~40 meg A/UX "Usr" partition on the internal drive using the MacOS utility "Apple HD SC Setup". Boot A/UX and verify the partitioning of the internal drive with "dp /dev/rdsk/c0d0s31". Try a mkfs of c0d0s0. No luck: it complained that any block count I gave was larger than the physical size. Same for c0d0s1 and c0d0s2. As a sanity check, I built a file system on the floppy drive c8d0s0, using diskformat and mkfs, and then mounting it. Worked fine. So, what am I leaving out for the hard drive? Do I need to do a diskformat of the partition? I'm assuming the slice 0 (s0) is the one I should specify, since this is the only A/UX partition on the drive, and mount tells me that / is /dev/dsk/c5d0s0 (the external drive). I used Apple HD SC Setup since that was what the diskformat man page said to use. Thanks for any help. I know I should wait for the manuals, but the other parts of the system have been trickling in over the space of three weeks, so who knows how long I would have to wait!

Last I looked, HD Setup missed some of the A/UX fields. Next, you need to use 'pname' to associate a partition on other than the boot device with a particular slice. On the boot device, slice 0 is the root partition, and slice 2 is the usr partition, if there is one. Non boot devices are not automatically searched. pname -a -c0 -s0 "Usr" (use the actual name you gave it) mkfs /dev/rdsk/c0d0s0 (and fsck, etc.) mount /dev/dsk/c0d0s0 /mnt ought to work.

Thanks to everyone who replied so quickly to my query. The answer was that I needed to use pname to identify the slice. Mark Nelson ...!rutgers!udel!nelson or nelson@udel.edu This function is occasionally useful as an argument to other functions that require functions as arguments. -- Guy Steele
