1989 Networking: OS/2 NetWare Requester 1.1
When I wrote about the pre-release NetWare Requester for OS/2, the oldest archived officially released NetWare OS/2 Requester was version 1.2 from 1990. In the meantime, version 1.1 of the requester showed up, although I only became aware of that … Continue reading

OS/2 6.304: Finally Complete
Some time ago, I lamented that even though the OS/2 Museum had a good number of disks of the final OS/2 2.0 beta, level 6.304, there wasn’t enough to install the OS, let alone any of the development tools or … Continue reading

Page Too Big
The other day I was able to look at an IBM OS/2 pre-release CD-ROM from early 1992. The CD-ROM appears to have been produced by IBM UK under the DAP (Developer Assistance Program) umbrella. The CD-ROM contains about 250 MB … Continue reading

Where Did CP852 Come From?
In the 1990s, a lot of my documents were written in code page 852 (CP852), also known as PC Latin 2. This code page is sometimes called “Eastern European”, which is a bit misleading, given that it does not cover … Continue reading

OS/2 6.304: Who Has More?
Yet another interesting item that I recently ran through a Kryoflux is a set of 30 floppies labeled “IBM OS/2 Version 2.0 Pre-release Evaluation Copy – 6.304”. In this case, there’s no mystery as to what it is: 6.304 was … Continue reading

OS/2 1.2 EE DAP
That same shoebox I mentioned the other day also contained three plain cardboard 3.5″ floppy boxes with a set of disks that look like this: Once again, despite the plain-looking labels, these are mass-duplicated floppies, which is handy because Kryoflux … Continue reading

Archival Puzzles
Every now and then I attack the large amount of floppy disks in my basement and run a bunch of them through Kryoflux. This time it was a shoebox full of OS/2 related floppies. Among them was a very incomplete … Continue reading

Installing IBM OS/2 1.0 in a VirtualBox VM
Some time ago I wrote that IBM OS/2 1.0 and 1.1 cannot be installed in a VM due to the way it switches between real and protected mode. At the time I did not realize that there was another obstacle, … Continue reading

MS LAN Manager NDDK Anyone?
For R&D purposes, I would very much like to get my hands on the circa 1991 Microsoft LAN Manager Network Device Driver Kit which was meant to support the development of NDIS 2.0 drivers. While it is obvious that some … Continue reading

Complications, Complications
The other day someone asked how hard it would be to modify the Open Watcom linker, wlink, to properly support exports from IOPL segments in OS/2 LX modules. Not terribly hard it turned out, all it needed was to emit … Continue reading
