I looked at the 2.4.20 output and saw ICH2M mentioned in the output. I then grepped the drivers/ide/pci files for ICH2M and found I just had to enable CONFIG_BLK_DEV_PIIX. In my defense I can only say that the Configure.help stated that this option only enables extended PIO modes. So for the record: A Dell Inspiron 8100 Laptop needs the CONFIG_BLK_DEV_PIIX to enable DMA. -- Lars - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
