  64-bit Slack/390x Available for Testing!
It's been a long time coming, and way over due, and not really ready yet, but here it is for testing. The installer and post-install configuration scripts still need quite a bit of work. But, if anyone is interested in testing, please do so. The files can be found in the 64-bit -current section at the usual place. Please report any problems to s390support at Thanks!

  Download directories rebuilt
Ibiblio had a hardware problem with the storage array that holds all the Linux distributions. I had to rebuild the download directories from the systems where I do my development work. Everything should be back to the way it was. If you see any problems, please let me know.

  64-bit Slack/390 Coming!
I'm getting close to finishing the 64-bit version of Slack/390. It will be equivalent to the Slackware 11.0 for Intel platform. The main tasks I have left are updating the installer, and adding functionality to it so that it will configure the network interface prior to the first reboot.

If anyone is interested in being an alpha/beta tester, please let me know.

  Removing Older Versions
At the request of the Ibiblio staff, I'm removing several of the older versions from the download server. They were getting a little tight on space, and asked that only the current version and at most two older versions be kept. So, I've deleted the 8.0, 8.1, and 9.1 directories. That leaves the 9.1, 10.0, and -current versions still available.

If anyone is really interested in getting a copy of any of those, please let me know. I did make a backup of the directories before deleting them.

  DVDs for Slack/390 are now available
Thanks to the generosity of John McKown of the Linux-390 mailing list, we are now able to offer DVDs of Slack/390 for people that want them. A nominal charge of $5.00 is involved to cover our expenses. If you're interested, please send an email to info at, and we'll work with you to make the necessary arrangements.

  Commercial support for Slack/390 is now available
Sine Nomine Associates has announced that they will begin to provide commercial support for Slack/390. Additionally, they state that they will be "adding Slack/390 CDs to our media creation service in the near future."

Of course we find this very gratifying, as it increases the number of choices people have in the Linux/390 community.

  Slack/390 10.0 is released!
The newest release of Slack/390, version 10.0, is ready to go. Thanks to everyone who downloaded and tested it, and reported any problems.

Highlights of the release include the Linux 2.4.29 kernel, with Linux 2.6.7 as an alternate choice in /testing, glibc 2.3.2, gcc 3.3.4, and apache 1.3.33. For a complete list of changes since Slack/390 9.1, check out the Slack/390 10.0 ChangeLog.

Read the official announcement here.

Note that because this release was delayed quite a bit after the Intel 10.0 version, there are a significant number of updated packages in /patches. Most of these are security fix updates, so if you install any of them from the main /slackware branch, please update them with the corresponding version in /patches.

As Pat says, Have fun! :-)

Welcome to the Slack/390 Project

Slack/390 is the official port of Slackware® Linux to the IBM mainframe platform.

Like all other versions of Linux for the mainframe, it can be run
  • "native,"
  • in a Logical Partition (LPAR),
  • or on z/VM.
It is intended to be a maintained, Free/Libre, and free (no charge) Linux/390 distribution. It is distributed under the GNU Public License (GPL), so you are entitled to use it, modify it, or redistribute it in any way you see fit. (There is one big exception to this.) If you modify it, you are not entitled to call it either Slackware or Slack/390, but that is about the only restriction. See the link to the Slackware trademark statement at the bottom of this page.

I try as much as possible to follow what Patrick Volkerding does with the Intel distribution. There are some obvious exceptions, but I do try to keep them to a minimum.

Currently there is no 64-bit version, since there is no 64-bit version of Slackware for Intel.

The one exception that does not have some sort of Open Source license is the IBM JDK. The license they include in the tarball says that it may only be redistributed under the terms of the license, but then it doesn't say what those terms are. I asked for clarification, but never received any. Since IBM doesn't charge for the download, and we're not charging for anything either, we decided to make it available as part of the platform. Of course, if we do hear differently, it will be withdrawn.
