3 * linux/drivers/ide/pci/cmd64x.c Version 1.42 Feb 8, 2007
5 * cmd64x.c: Enable interrupts at initialization time on Ultra/PCI machines.
6 * Note, this driver is not used at all on other systems because
7 * there the "BIOS" has done all of the following already.
8 * Due to massive hardware bugs, UltraDMA is only supported
9 * on the 646U2 and not on the 646U.
