First of all. This is a great OS/2-forum
I would start programming a VESA-Display-Driver for OS/2 1.x (for nostagic reasons), and search documentation for it?
Can anyone help me?
Best regards

Read what he wrote, Ben. He is talking about OS/2 Version 1! GRADD is not available there, neither is the PM we know.
Thats right chennecke.
I'm searching infromations for programming Display drivers for OS/2 1.x
With best regards

An OS/2 2.x PDD (physical device driver) is pretty much the same as an OS/2 1.x device driver.
OK, OS/2 1.x device drivers are bi-modal -- they run in real mode and in protected mode. The real portion of the device driver will load below the 1 MB line. A 1.x device driver is packaged as a 16-bit exe, with one code seg and one data seg marked real. Any other segs can load above the 1 MB line.
Probably most of the DDK still applies if you make a PDD, you will have an OS/2 1.x driver.
Better get a copy of Deitel and Kogan, too.
Thank you Blond Guy
I've orderd Deitel and Kogan.

Hi Reini1976.
Just being curious. Under which machine are you going to make this development?
I never used OS/2 1.x and I will like to test it out (also for nostagic reasons) but I never found any emulator that I can make it work on modern hardware.

Hi miturbide
It is possible to run OS/2 1.3 in VirtualPC. But it is not possible to install it on Virtual PC.
That means: Install OS/2 1.3 on real old machine. Make a image from the hard disk, and use it in Virtual PC
Look at http://pages.prodigy.net/michaln/history/vm.html
