Continuing from the previous post, let’s get started with Microsoft OS/2 1.1
I added a 500MB hard disk to VirtualBOX, booted up an OS/2 1.1 boot diskette I had created that allows me to fdisk/format and do basic backup/restores, esp since OS/2 1.0 cannot install on a large (lol) 500MB disk.
So with the restore done, I’m booting up the Microsoft OS/2 1.1c Nokia OEM release.
The dates for this release is 2/20/1989. Â I would have imagined that the original version of OS/2 1.1 shipped in 1988, as mentioned by the copyright. Apparently the Microsoft versions of OS/2 1.0 & 1.1 included support for the 386 method of switching from protected mode to real mode, while the IBM versions only included the 286 triple fault method. Â I’d imagine the Microsoft ones would include both, but the only way to verify is to install on a 286. Â Something that I simply do not have.
This style of the OS/2 installer will be with us for quite some time. Â it’s not until Warp did the look and feel start to change.
The setup program renames my config.sys , autoexec.bat and startup.cmd files. Â Obviously things are now different from OS/2 1.0
For some reason things like serial ports are optional, so after letting it load the serial driver, we are all set to go!
And the C drive has been cleaned up… some. Â Although most of this stuff is backups of my OS/2 1.0 stuff, along with some portion of the OS/2 1.0 install in os2.000 .. I just deleted all of this crap.
Now to see OS/2 1.1 in action…
So again you are limited to 12 sessions in OS/2, along with the single DOS Box. Â However notice that the windowed icons (the black ones) and the full screen areÂ independent. Â This was also another annoyance in OS/2, that you cannot switch an application from full to windowed at will, and some text mode stuff is compiled as full screen so launching it from a window will jump you fullscreen. Â OS/2 also finally included a game, a breakout clone, with various neat pictures. Â I like the Seattle one myself.
And a text editor! A nice one too. Â Also I don’t know if it’s VirtualBOX but the UI is VERY sluggish, the worst thing you can do is open a command window and have it scroll.
But all in all, OS/2 1.1 was certainly a step in the right direction, and really what people would start to expect in an OS. Â The GUI really is needed to get a feel for multitasking. Â It’s a shame that ‘paging’ the real mode box out to disk and going between multiple sessions could have been done…. But I imagine they tried it, and it failed badly. Â Or the paging got out of hand.. Hard to say.
As a slight detour I’ve also setup IBM OS/2 1.1 Extended Edition, which you can see my quick review here.
And for the few people who care, here is what 1.1 in Mono EGA mode looked like:
The other things that Microsoft OS/2 is really lacking is online documentation, and a way to shut down the OS from the desktop. It’s still control-alt-delete.
Onward to OS/2 1.2
