UltraPenguin – a Linux distribution for SPARC and UltraSPARC based workstations, which is based on Red Hat Linux. This distribution is for both 32bit and 64bit SPARC CPUs, the advantage is that this distribution works on 32bit SPARCs (sun4 (hopefully, SILO not yet, install image neither), sun4c, sun4m, sun4d) and on 64bit SPARCs.

It is released under GPL. There are really no guarantees and you cannot make Red Hat Software, Inc. liable for anything, as this is really just based on their work.

Supported Hardware CPU’s:
– Sun4 machines (4/300 only at the moment)
– Sun4c machines (IPC, SS1, etc)
– Sun4m machines (IPX, Classic, SS5, SS10, SS20, …, including SMP boxes; only SS5/170 is not yet supported)
– UltraSPARC SBUS based workstations (Ultra1, Ultra2, Ultra1 Creator, Ultra2 Creator, including SMP configurations)
– UltraSPARC PCI based workstations (Ultra30, UltraAX, Ultra10, Ultra5, Ultra60)
– UltraSPARC SBUS based servers: Enterprise 1, 2, 150, 3000, 4000, 5000, 6000, 10000 (SMP is being worked on)
– UltraSPARC PCI based servers: Enterprise 450 (including SMP)

UltraLinux is a fast 64bit free operating system, which supports up to 1TB of physical and another 1TB of IO memory, fully supports Linux/Sparc 32bit binaries plus will soon support 64bit UltraLinux ELF binaries. It uses the Visual Instruction Set for high bandwidth operations, even older 32-bit applications take advantage of this increased performance if they are dynamically linked. The 64-bit userland for UltraPenguin is half done, developers have initial statically linked ELF 64-bit binaries working. We will announce separately the availability of this so others can experiment with it and help us out, so please be patient.

July 12, 1997 – The UltraLinux team announces UltraPenguin 1.0 which was based on Red Hat Linux, version 4.2 for sparc.

Unifix – a Linux CD-ROM distribution with emphasis on easy and fast installation. Though it is possible to install everything on the harddisk, it is not recommended so, because it runs fast enough directly from CD.

The dynamic buffer cache of Linux takes care of the second and subsequent times a program is started, which needs less than one second.
The system requires about 5 MB on the harddisk for configuration files and system management tools. Additionally it is recommended a 16 MB swap partition. The distribution (version 1.02) contains most of the standard programs in current versions, e.g. Linux 0.99.15e, XFree 2.0, emacs 19.22 and gcc 2.5.7. Full preconfigured source for everything is included.

Because Unifix is a European distribution it provides full support for iso8859-1 character sets. From the shells and emacs through ls, TeX and the print system everything supports 8-bit characters.

Printing is supported through System V compatible printer drivers which can be controlled through lp’s -o options. Printer drivers are included for dumb text mode printers, for postscript- or ghostscript- compatible printers and for networked printing. These drivers know how to guess the type of the files so e.g. compressed man pages or DVI files can be printed directly.

Unifix Linux 2.0 is the successor of Unifix Linux 1.8 and Linux-FT 1.2. Linux 2.0 supports a lot of new hardware which was formerly difficult or impossible to use under Linux. These are new SCSI adapters (e.g. 53C400), improved support for other cards (e.g. 53C800, AHA2940), new network cards (e.g. SMC 9000, 3com590), several new multi-port serial cards, several ISDN cards from cheap passive ones to fast active cards for use in servers.

Unifix was available only on CD. It comes in a Unifix/Linux binder with two boot floppies and about 70 pages of installation instructions in German. An English version would be available Apr 1994. The price was 159 DM (about $100) and includes taxes and shipping.

PicoBSD – a one floppy version of FreeBSD, configured mainly for networking applications. It can be used as a router or firewall, or kind of a fixit floppy (or all of them).

Minimal requirements:
– 386SX CPU or better (there is an FPU emulator in kernel)
– 10MB RAM – the more the better. If you have an HDD, you can make a swap partition or swap file (using vnode driver and vnconfig). Then you probably will be able to run with ca. 6MB only
– Modem sitting on COM1-COM4 (default is to use COM2), if you want to have a PPP connection
– Network card: compatible with NE2000, PCI Intel, 3Com 3c509 or with DEC chipsets (ed, ep, fxp and de drivers). The kernel supports two of them (i.e. 7 total) plus two PPP connections (tun interfaces). So you can easily build something like router with as many as 9 outlets

The project developer is Andrzej Bialecki, and newer version is Dinesh Nair.
The latest floppies of version 0.42 were built from 3.0-current sources. Though they provide more features, they tend to be less stable than the latest RELEASE of FreeBSD. Dinesh Nair back-ported these scripts to the latest release (2.2.5), and continues development of PicoBSD using sources from that branch.

In April 2, 2005 Volker Ruppert created an ‘img’ image of PicoBSD. The directory contains a bootable floppy image of PicoBSD, which is a teeny version of FreeBSD. I have been able to get it to boot, as long as I tell it not to probe for a mouse.

PicoBSD is now included in the FreeBSD source files where it is used by embedded system developers to create their own system images. It can be used with recent versions of FreeBSD and it is located in /usr/src/release/picobsd/.

In FreeBSD 5, it has been superseded by the NanoBSD framework.
