It sounds like you used the commad: cpio -i[vldm] < /dev/rdsk/f0q15dt

You need to use the command:        cpio -i[vldm] < /dev/rdsk/f0q15d

The f0q15dt device refers to the entire floppy including the boot
track.  The f0q15d device does not include that track.  Microport used
this trick to put an index(??) on each disk in the boot track,
"diskdata", in addition to the "real" cpio file.

You're just using the wrong device.  Probably some command like;

cpio -ivt < /dev/rdsk/0s25

Right?  Well, you're only off by a smidgen.  Try;

cpio -ivt < /dev/rdsk/0s24

which will list the contents of the floppy.  All other applicable commands
for cpio will work dandy with /dev/rdsk/0s24.

Cheers!

   When you execute pkginstall, it actually just goes and runs a shell
 script called /etc/installit. Looking at this script you can see there
 are several forms of cpio it will use depending on what you were doing.
 Mostly they are pretty similar and will serve your purpose. Here they are
 from installit:


     cpio -iu </dev/rdsk/f0q15dt 2>/dev/null

     cpio -icBdmu $1 </dev/rdsk/f0q15d 2>/dev/null

     cpio -icBdmu </dev/rdsk/f0q15d

   
   As you can see the key is using /dev/rdsk/f0q15d. I have selectively
 restored many files from the distribution disks this way and it works
 great. Good luck.

Thanks to Eric Schnoebelen (eric@cirr.com) for providing the a pointer in the
right direction. The install disks have two sets of files on them, the
"diskdata" file that I referred to in my original posting and a second set of
files, a cpio archive, which you get to by specifying the disk device that
excludes the boot tracks. To recover the file, I then used:
	cpio -idu < /dev/dsk/f0q15d "*acctcon2*"
which recovered the file in a subtree under the current directory. That was
the easy part. The hard part was going through all the disks to find which one
to insert for the cpio command (it was something like the 5th or 7th disk).
