OS/2 Warp 3 Graphics Card Selection Input?

<< < (2/2)

Marc Galloway:
Thank you all for the information. I think with all the info you all provided I'll be able to source a card. Great info about SNAP being supported. I'll do so digging on where to download the fixpacks and how to install. Thanks again.

Martin Iturbide:
Hi Marc

Just feel free to open a new thread when you start installing and tuning Warp 3 on your machine. Warp 3 has a variety of Fixpacks depending on which component you need to update.

Here it is a good page to give you some hints: http://www.altsan.org/os2/fixpaks/fixgraphics.html


Marc Galloway:
Thanks Martin. Will do, I'm sure I'll need help as I get ready to go down the OS/2 path.

Dariusz Piatkowski:
Late response on my part, but if I recall correctly Matrox was a very strong OS/2 player back in the day. Their native drivers did well, as does the SNAP support, specifically the current readme shows the following:

--- Code: ---. Matrox MGA Millennium, MGA Millennium II, MGA Mystique
. Matrox MGA Mystique 220, MGA-G100, MGA-G200, MGA-G400, MGA-G450
. Matrox MGA-G550, Parhelia, MGA-P750, MGA-P650

--- End code ---

The Matrox MGA-G450 & MGA-G550 are also supported in the MultiHead mode, although not sure if these came in ISA configuration.

Finally, are you limitted to ISA only, or does that board have VESA connector?

What would some graphics card recommendations be as I know driver support was always an issue with OS/2 that didn't get better to WARP 4. Been searching for a compatibility matrix for what drivers where included in WARP 3 but having a hard time tracking that down.

Trident ISA cards using IBM drivers are the best bet for ISA, some of the Trident ISA drivers even have features that later drivers do not support such as changing resolutions without rebooting etc. Pro level ISA cards such as Matrox, S3 et. al. work well but are impossible to find. Tseng Lab. cards work well too, but have slow DAC's, but superb DOS support. Cirrus Logic (aka acu MOS, etc), ATI and SiS also work well but similarly have a slow DAC with the exception of a couple of ATI cards.

Almost any ISA card can be made to work actually, I used an obscure Avance Logic (aka Realtek) ISA card for years, that I have never seen offered for sale before or since, despite keeping an eye out for it on eBay for a quarter of a century.
