I was having the exact same error message when trying to set the dma to 1. I needed an extra option in my kernel and thus a kernel compile. Make sure at least these are set CONFIG_BLK_DEV_IDEDMA_PCI=y CONFIG_BLK_DEV_IDEDMA=y For me, it also involved setting CONFIG_BLK_DEV_PIIX to yes since my server has a PII motherboard so make sure the appropriate chipset is loaded for your motherboard Regards, Benedict -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
