I installed this controller because it supports ATAPI devices. I connected my Plextor PX708a burner on to it and tried to do a burn. When it goes past 4x speed, the buffer keeps emptying and slowing down the burn.
Found out from the Silicon Image ATA controllers icon in the control panel that the drive is running in multi-word dma mode 2. To test further, I plugged a cdburner into this and it is also set to multi-word dma mode 2.
Not sure if this is causing my issues.
Anyone using this PCI controller know how to manually set the burner to Ultra DMA mode 2? What mode are your ATAPI devices reporting that are connected to this controller?
For now, I ended up taking this controller out and plugging the burner back to one of the onboard IDE controllers.
