ご質問: When I play media files with SATA hard disk on 939A8X-M / K8A8X-M / K8Upgrade-1689 / K8COMBO-Z, the screen lags and the sound also becomes abnormal. How should I fix this problem?(11/18/2005) 答え: Please install the ULi SATA RAID drivers. Even you set non-RAID mode in BIOS and install OS successfully, please still install the Uli SATA RAID driver to get better performance on SATA devices.
