I think, unfortunately, the Trident 8900D (and probably other 8900 models) does not have good support for 256 colors on 286 systems. The only driver I found that works is for Windows 3.0, and it is extremely slow and has many issues.
In fact, just for testing, I built a 486 DX4 system and installed the same Trident card, the same ISA sound card, and the same CF card I use in my 286 (same Windows installation). When I loaded Windows 3.1, performance was just as slow as on the 286.
Then I assembled a 386SX-25 (a very slow board I have), installed the Trident 386 drivers, and performance was actually quite fast.
From all the testing I’ve done, my conclusion is simple: Trident Windows 3.1 drivers for 286 systems are very poor... SUCKS
Thanks for help

Hi, i download the trident driver from this compilation, but sadly same as others, the "good" 640x480x256 driver need 386, and the 286 one is anciend win3.0 one, slow and full of problems

https://archive.org/download/trident-tvga-890 … er-disk-trident - this one is later, the TRW one readme says that some require 386, this one doesn't mention
Sadly this driver if you expand amd check TRIT640.DR_ 640x480-256C , have this text This driver ONLY can work on 386/486 machines or above..
thanks
