#os-2 — Public Fediverse posts

#OS2-aikoina (oik. OS/2) muokkaimena oli sitten IBM:n oma #EPM, joka oli aivan käsittämätön häkkyrä. Muistan, että aina välillä sen sai hetkittäin toimimaan miten halusi, mutta sitten taas jossakin jokin särkyi. Se koostui ohjelmatiedoston lisäksi isosta joukosta toisiinsa linkittyneitä määritystiedostoja, ja aina välillä purkkaviritys poksahti naamalle.

Had an alternate-history thought experiment: what if OS/2, not Windows, became the default PC world?

IBM and Microsoft never split, Warp becomes the household name, Workplace Shell rules the desktop and PC gaming grows up around OS/2 instead of DOS/Windows.

The whole culture of 90s computing shifts in a very different direction… or would it?

OS/2 Warp 4.52 on 86Box with Super Socket 7 [1998]

OS/2 was a proprietary operating system that was initially developed by IBM in partnership with Microsoft as a replacement of DOS before it became entirely developed by IBM. OS/2 Warp 4 was officially released in 1996, and development slowed down to a halt because it failed to compete Microsoft Windows. OS/2 Warp 4.52 was officially released in December 2001, and this year, it will celebrate its 25th year anniversary.

Our focus in this article is testing OS/2 Warp 4.52 on an 86Box emulated machine with a Super Socket 7 [1998] motherboard. You can download it from here.

We’ve configured the virtual machine as follows:

We’ve configured a virtual machine to run with:

• Machine type: [1998] Super Socket 7
• Machine: [SiS 5591] Gigabyte GA-5SG100
• CPU: Intel Pentium @ 166 MHz
• Memory: 128 MB
• Video: [ISA16] Cirrus Logic GD5434
• Keyboard: AT Keyboard
• Mouse: PS/2 Mouse
• Sound card: [ISA16] Sound Blaster 16 PnP
• Floppy disk controller: Internal device
• Hard disk controller 1: Internal device
• New hard disk: os2warp452.vhd
  • C/H/S: 1054/16/63
  • Size: 518 MB
  • Bus: IDE
  • Channel: 0:0
• CD-ROM drive 1: ATAPI (0:1) KENWOOD CD-ROM UCR-421 208E (72x)

Once everything is configured as above, we can now start the virtual machine. Insert the boot disc called mcp2-refresh-boot-en.iso to the CD-ROM reader, then configure BIOS as necessary.

To be more specific, we need to go to the BIOS setup using DEL and change the boot order so that CD-ROM goes first with PGUP/PGDN.

After that, we save the changes and restart the virtual machine.

The installer starts by telling you to insert the installation CD-ROM to the drive.

In this case, right-click on the CD-ROM icon, select “Insert…”, select mcp2-refresh-install-en.iso, and double-click it. Then, press ENTER.

After that, you should be able to see this welcome screen:

Press ENTER, and you’ll be taken to another screen that welcomes you to the operating system installer.

Press ENTER. At this point, since it’s a fresh installation, and the hard drive is already empty, you’ll get the “Volumes Too Small” message. This means that you’ll need to create a single partition that will be used to install OS/2 Warp 4.52 to.

Press ENTER, and you’ll get a warning message telling you that all data on modified volumes will be deleted, and that backups should be made. Since there is no data on the hard drive, you can safely ignore this warning. Just press ENTER.

After that, you’ll be taken to the partitioning screen where you’ll be presented with the logical volume manager, with the logical view being the default. Press F5, and you’ll be taken to a screen where you can see your hard disk, such as the below screenshot:

Here, you can create a physical partition. Press TAB, then ENTER, and you’ll be presented with those options.

Press ENTER to create a new partition. You’ll be asked whether this partition is going to be logical or primary. Select “Primary partition”.

After you select it, you’ll be presented with various dialog boxes telling you to specify the size and the name of the partition, as well as the position of the partition. Select “Create at the start of the free space”, then enter the partition name, then the size.

After that, this partition should be created.

We are not done yet when it comes to partitioning, so we need to go back to the logical view. Press ENTER, then press ENTER on “Create a new volume”. Then, select “Create a volume that can be made bootable”, then C:.

You’ll be brought back to the physical view that will tell you to choose a physical disk. Below the physical disk, the logical partition should be shown at the bottom of the screen. Press ENTER when this dialog box appears.

Press ENTER again, then select “Use existing partition”.

Now, a new logical volume will appear with the partition name that you’ve chosen. However, it’s still not ready yet for installation, since there are extra steps that are needed. We need to make it installable.

Press ENTER, and you should see the menu box below:

Select “Set the volume installable”. The status of your logical volume should change from “Startable” to “Installable”. Afterwards, press F3, and press ENTER when “Save the changes and exit” is highlighted.

Afterwards, you should be able to see the below dialog box telling you to insert the boot CD-ROM to the drive and restart the virtual machine using CTRL + ALT + DEL.

At this point, we need to change the BIOS boot order to avoid the black screen issue. Press DEL, go to BIOS Features Setup, and change the boot order so that CD-ROM goes first.

Then, exit the BIOS setup while saving changes, and follow the instructions all the way until the following screen shows up:

Verify that “Volume C” shows up. If not, you’ll have to configure the partitions again until the volume shows up in this screen. Since we’ve already configured everything, and that Volume C corresponds to our hard disk, press ENTER when “Accept the volume” is highlighted.

Then, the installer asked us whether we’d like to format it slowly or quickly. This is a clean installation, so we’ve chosen a quick format. Then, the installer asked us whether we’d like to use FAT or HPFS. We’ve chosen the HPFS file system.

After that, the installation of the base system begins.

After that, the virtual machine will automatically restart. Go back to the BIOS setup and make sure that the C drive comes first before the CD-ROM.

After that, OS/2 Warp should boot up to the GUI portion of the installer. The first thing you’ll be presented with is the configuration of the system, including the country, the graphics adapter, and the sound adapter.

First of all, we went to “Multimedia Device Support”, and added the SoundBlaster 16 PnP device to the list of installed devices.

Afterwards, we’re presented with another set of configuration, once we’ve selected “Next”. SInce there’s no need to configure anything on that screen, we’ve just clicked Next. Then, it presented us with options to choose the country/region, with the default selected country being “United States.”

Then, the printer configuraion window has shown up. SInce there’s no printer installed, we’ll leave it as it is.

We’re then presented with the graphics adapter configuration. It automatically selected the Cirrus Logic graphics adapter as we’ve chosen earlier for the virtual machine configuration.

Once we’ve selected OK, we’re then presented with a set of packages to install.

As soon as we clicked “Next”, we’re presented with another wizard that lets us configure some more services.

Once we clicked Next, we’re presented with a prompt to identify ourselves.

After that, we’re given another set of software packages to install. They represent the client services for OS/2.

Once we clicked Next, we’re presented with another configuration screen where we needed to configure the user ID and password for the file and print sharing services, and the network adapter and protocol services.

We went to create a new ID and a password for the sharing service

Then, we went to “Network Adapters and Protocol Services”, and a dialog box that told us to add a network adapter appeared. Since we don’t intend to have internet connectivity in this installation of OS/2 Warp 4.52, we’ve selected “No network adapter.”

Once we pressed OK, we’ve seen this result:

Now, we’ve pressed Install, and a confirmation dialog box appeared.

Now, the installation of the remaining system files started here.

Once it was done copying files, we’re asked whether to use the defaults for the monitor type or to use the display adapter utility program.

We’ve chosen the defaults, and an informational box appeared stating that the screen might flicker while the testing was underway.

After that, the remaining portions of the installation started. This is part one of the long waiting journey!

After the restart, depending on the region selected, OS/2 Warp 4.52 might tell you that there’s something wrong in the CONFIG.SYS file related to the codepage, just like below.

After that, the long waiting journey continues…

The system then restarted, and the desktop finally appeared, but with another dialog box asking us whether we needed to install sets of extra tools or not.

We’ve chosen the biggest option, which was “OS/2 Toolkit (English only)”. Then, we’ve clicked on Install once we’ve inserted the boot disk back to the CD-ROM drive.

Then, a configuration window where it tells us to configure the installation of the OS/2 Toolkit, just like below.

We’ve chosen to install everything, so we just chose Install. Yet another long wait journey starts…

After the installation of the toolkit reached 100%, a dialog box that told us that the installation was successful showed up. Once done, we’ve clicked on Quit in the toolkit installer.

Since the dialog box told us that the CONFIG.SYS file was modified and that we needed to restart the virtual machine. Therefore, we’ve clicked on Exit, then right-clicked on an empty area around the desktop and chose “Shut down”.

Once the shut down was done, we had to press CTRL + ALT + DEL in the virtual machine side. After that, the system booted up to the desktop, and the sound works!

Nostalgic, isn’t it?

Catch of the Day: The OS that tried to beat Windows! 🏢🔵

Hey Retro Fans!
Hold on to your floppy disks, because the FrogFind radar has caught a true piece of computing history today. Among all the Nintendos and old Macs, an operating system appeared that will make IT veterans immediately nod in respect: OS/2!

Our bouncer logged this fabulous guest:
Mozilla Firefox 48.0 running on OS/2

For the younger frogs in the pond: OS/2 was developed jointly by IBM and Microsoft in the late 80s and was intended to be the successor to DOS. It was technically superior, and its stable multitasking was a dream! But then Microsoft released Windows 3.1 and later Windows 95, the partnership shattered, and IBM's "better Windows" lost the great war for home computers.

The fact that today, in 2026, someone is browsing the web with OS/2 (probably via a modern continuation like ArcaOS or eComStation) and a specifically ported Firefox 48 is pure, unbridled love for the platform. OS/2 lives, and it uses FrogFind!

Cheers to the OS/2 Warp veterans!

It’s an OS/2 system! I know this!

Catch of the Day: Greetings from the OS/2 Warp Dimension! 🌀💻

Hey Retro Fans!

Our radar is glowing, and today we’ve caught a guest in the Frog pond that catapults us straight back to the mid-90s, right into the middle of the great operating system wars: Netscape Navigator 4.61 on IBM OS/2!

For those who don't remember: Before Windows 95 dominated the PC world, IBM and Microsoft worked together on OS/2. After the two giants split, IBM released OS/2 Warp as a direct competitor to Windows. It was technologically superior, ran extremely stably, and had fantastic multitasking—but ultimately lost the marketing battle to Microsoft.

The fact that today, in 2026, someone boots up a real OS/2 machine, launches the native Netscape Navigator 4.61, and uses it to ping FrogFind is retro computing at the absolute highest level. A true digital dinosaur proving that good software never truly dies.

May your multitasking always run smoothly!

Non ho ancora avuto occasione di provare OS/2, ma trovo che abbia una interfaccia molto ricca ma anche snella.
So che c'è ArcaOS come versione piu moderna, ma sapete se ci sono reimplementazioni open source per fare una prova diretta?

Catch of the Day: Greetings from the OS/2 Warp Zone! 🌀💾

Hey Retro Fans!
Today, we're shining our spotlight on a very special operating system in our logs. Someone actually visited the Frog pond using OS/2!

With 4 clicks, Mozilla Firefox (Version 45.0) running on an OS/2 system showed up in our stats.
For those who weren't around in the 90s: OS/2 was IBM's legendary answer to Windows. Back then, it was often praised as "a better DOS than DOS and a better Windows than Windows." The OS/2 Warp version, in particular, brought true, rock-solid multitasking to PCs long before Microsoft pushed it into the mainstream with Windows 95.

Although OS/2 ultimately lost the commercial battle for the desktop, it still retains an incredibly loyal and brilliant hardcore community today (partly through modern successors like ArcaOS) who even compile newer Firefox ports for the system. We think it's absolutely fantastic that this technical masterpiece is still being used today to browse the Frog pond!

May your systems never crash!

Catch of the Day - Good Friday Edition: Of Ataris and Crazy Emulators! 🕹️🦇

Hey Retro Fans!

You just don't stop amazing us! Our log files from the past 24 hours read like the script for a documentary on crazy hardware tinkering.

The absolute highlights of the day:

🦇 Atari ST is online: We had visits from HighWire – the custom-built browser for Atari's classic TOS (Tramiel Operating System). It’s an incredible feeling to serve our text content to a 16-bit system from the late 80s!

🎮 Netscape 4.0 on a PSP?! Yes, you read that right. Someone actually got the Netscape Navigator from 1997 running on a PlayStation Portable (with a massive 653 clicks!). This is most likely running via a homebrew Linux port or a DOSBox emulation on the handheld. Absolute madness!

👔 The Business Dinos live: We also recorded visits from old BlackBerry 10 devices and a genuine IBM OS/2 Warp system!

Whether you’re dragging your old Ataris out of the basement or testing obscure emulators on consoles – the Frog pond is open for you. Keep it up!

FrogFind's "Catch of the Day": A Greeting from IBM! (OS/2 Warp) 🚀🖥️

Hey Retro Fans and have a great weekend!

Today's Catch of the Day takes us right back to the mid-90s, straight onto the battlefield of desktop operating systems. Around 1:20 PM, we recorded this beautiful entry:

🏆 Netscape Navigator 4.61 on IBM OS/2

Why is this so cool?
Long before Linux on the desktop was a thing, there was a giant competitor to Microsoft's Windows 95: OS/2 Warp by IBM. It was incredibly stable, true 32-bit, offered outstanding multitasking, and was deeply loved by power users, banks, and network specialists.

Unfortunately, Microsoft ultimately won the marketing war, but OS/2 still has a small, incredibly loyal fanbase today (and even lives on in modern forks like ArcaOS!). The fact that someone booted up their old IBM machine (or a virtual machine) this afternoon to surf FrogFind using the classic Netscape 4 is pure retro dedication.

OS/2 lives! And on FrogFind, it loads faster than ever. 😉

FOOF. Воспроизводим легендарный баг в процессоре Pentium

Приветствую всех! Думаю, при упоминании знаменитого бага в процессоре Intel Pentium на ум сразу приходит ошибка деления . Но, как оказывается, она была не единственным косяком этих чипов. Первые “пеньки” имели ещё одну интересную особенность: существовали “роковые” четыре байта, выполнение которых заставляло компьютер зависнуть намертво.

ArcaOS 5.1.2 released

While IBM's OS/2 technically did die, its development was picked up again much later, first through eComStation, and later, after money issues at its parent company Mensys, through ArcaOS. eComStation development stalled because of the money issues and has been dead for years; ArcaOS picked up where it left off and has been making steady progress since its first release in 2017.
