Dear Sir/Madam,
Thank you for contacting MSI Technical Support.
Due to Microsoft still haven't release professional Vista and these controller vendors also haven't released professional drivers for Vista, currently we wouldn't release the drivers for Vista on our web site or send the drivers for our valued users . We'll just release the relevant driver after all the test for these drivers are OK when the professional version and drivers are released by Microsoft and our controller chip vendor. If you want to use Vista, please try to contact the chipset vendors for help.

Sorry for any inconvenience caused.
Best regards,
MSI Technical Support Team
