hi all Just a quick thread to let people know who are using: VIA HYPERION 4in1 drivers for gaming/performance like i am useing! when you load the version 449 your UDMA and PIO mode in device manager will disapear! and the tool from via loads to the start menu under VIADMA TOOL you click it then it goe to system tray! then you can open it from there! This had me perplexed for about 10 mins! so if you find yourself in the same boat when trying to sort out drivers and cd/dvd drives you will know! so got there in the end! Have to watch out for this if you use the new drivers HYPERION version! (gaming ones i think?) it takes it out of DEVICE MANAGER !! Thx all! Party on!!!
