What kernel version is this? If its a 2.2.x series kernel, try patching it with Andre's IDE patches. I've had good luck using UDMA/33 on a SiS530 (which uses the 5513 ide chipset) using Andre's patches. I've also been able to use UDMA/33 and UDMA/66 with the latest 2.4.x kernels and an 80-conductor cable (very important!). I haven't tried 2.2.x+ide with UDMA/66, though it should work as well. -- -Steven "Voters decide nothing.
