Why is it that SVGA doesn't seem to work in TP for me

Hello,

I have been trying for a very long time to install SVGA-drivers like SVGA256.BGI. But in some way my screen always goes blank and my system becomes stuck.
Maybe it is my SVGA-card (Tseng ET4000), but I think I am doing something wrong installing the driver. Can someone please tell me how it is done ?

Thank very much,

Abel Enthoven
