tahas
"Windows 98Gold/98se/Me/2000/XP/2003(32/64 bits) for Driver only. For Windows 98 SE, DirectX(R)8 is required to enable advanced features. (Executable file)"
a spustis

Inac v tych WinXP musis mat aspon SP1, idealne SP3

P.S> ale ked mam tipovat, tak tipujem ze nemas nainstaleny chipset driver.
