Trident CyberBlade XP Driver for Win2k and WinXP. Tested on Toshiba Satellite Pro 4600 Notebook/Laptop (CyberBlade XP 16MB AGP 4x) ...
Works perfectly fine :)
(and its a newer version than the one you can download on the Toshiba Support/Download Page)
You may need to manually install it.
right-click on "My Computer", Properties, "Hardware" tab, Device Manager...
doubleclick on "Display adapters" and rightclick -> update driver.
click on "install from a list or specific location", don't search, have disk and point to the folder where you unpacked this driver here to earlier :)
Have Fun :)
