Does anyone use an Acard IDE-Adapter?

Hello! I have an old PPC 9500 with a built-in scsi-bus (2 actually) and an Acard PCI-IDE-Card (AEC6260R). I have SuSE 7.3 on the old scsi-drive sda. The program does recognize the IDE-card and the drive attached to it, but I get boot-messages like hde: lost interrupt, lost irq func only, dma_chipset ???, and the drive is being probed for ages. I tried to install Macos under MOL on it, but I gave up, because it takes ages. It will probably run all night for an installation. Has anyone solved these problems? Marianne
