I do not claim to be any kind of an expert in this subject. I do claim that I can run both DOOM, and DOOM2 under OS2 Warp. My system is a Packard Bell Force 102CD, with 16 meg RAM, a 90Mhz CPU, I run OS2 Warp with WIN/OS2 support, using HPFS exclusively. I use a native OS2 sound driver for my sound card which I got from Packard Bell (they gave me excellent support upgrading to OS2 Warp from the Microsoft OS of the day) and installed. Video is run at SVGA Mode, giving me seamless windows support. These settings I arrived at by constantly tinkering with the settings. Regretfully, I cannot get full sound, and I cannot get the Joy Stick to work, either with or without the OS2 Joy Stick driver in the OS2 config.sys file. If anyone can improve on these settings, please let me know. Enjoy!!!
First, select full window.
Then under DOS settings, select all.

If you tweak and find better settings, especially for sound, please let me know. You must set your DOOM setup with keyboard and mouse, no joy stick, and use music for you're sound card, but sound effects must be set for your PC speaker to work.
Although the sound is crappy, the video is excellent, and the game is enjoyable.
