How to enable Dualview on Toshiba Tecra 780DVD

[AhMun]

Hello.

Does anybody know if I can do any kind of firmware update or other method to enable Dualview for a Toshiba Tecra 780DVD laptop?

Here are specs on my laptop:
- Pentium II MMX 266mhz
- Windows XP Pro
- 128mb Ram... (yes... WinXP works on such a slow system
- s3 ViRGE MX

Microsoft's Support page does not list the s3 ViRGE MX as compatible for dualview. But i'm not fully convinced... that if I have options for s-video, vga, and rca out... I think I should be able to do dual view, too...

Thanks!
