[RESOLVED] TSENG ET4000 only w/ 256 colors ???

Help! I have another 486DX/2 66 with a TSENG ET 4000 now and want to use it for retrieving emails. The videoadapter has 1 MB memory but i never get higher than 256 colors... but with 1 mb it should be possibly to have 16bit ???
does someone know what to do ?
tnx!

did you download the specific driver for that card cuz if you use the generic 95\98 one it will prob only do 256. Get the right one from windrivers
