Hello. Please help me with unpacking of SCO boot disks available here (and particulary 'uod429a.Z' for Open Desktop 3.0): http://www.lubkin.com/SCO/boot-media.html
When I tried to unpack on Unixware 7, it gives an error "Not in compressed format".

Re: Unpacking of SCO boot media
Not every archive there can be uncompressed with BSD compress. My attempt of following your advice was looked like this:Kenneth wrote:BSD compress(1) and uncompress(1) should do the trick.Code: Select all

Re: Unpacking of SCO boot media
Regular old gzip 1.9 worked for me...
Code: Select all
$ /usr/local/Cellar/gzip/1.9/bin/gunzip uod429a.Z
$ file uod429a
uod429a: data
$ ls -l uod429a
-rw-r--r-- 1 root staff 1474560 Sep 8 16:27 uod429a

Once again it's failed (I've tried it this time on TrueOS 18.03):Kenneth wrote:Regular old gzip 1.9 worked for me...

Re: Unpacking of SCO boot media
Thank you everybody. Now I've successfully unpacked uod429a.Z on Fedora and now can test SCO Open Desktop 3.0 (CD-ROM without boot floppy is available on FTP). It looks like gzip works differently on Linux and BSD.

Re: Unpacking of SCO boot media
It could be interesting to see if there is something different about the archive format that is making it behave that way. If you ran the "file" command on the archive on a modern Linux system, does it report back something unexpected?
