669a5db4 JG |
3 | * (C) 2005 Red Hat Inc |
4 | * Alan Cox <alan@redhat.com> | |
5 | * | |
6 | * Based upon | |
7 | * linux/drivers/ide/pci/cmd64x.c Version 1.30 Sept 10, 2002 | |
8 | * | |
9 | * cmd64x.c: Enable interrupts at initialization time on Ultra/PCI machines. | |
10 | * Note, this driver is not used at all on other systems because | |
11 | * there the "BIOS" has done all of the following already. | |
12 | * Due to massive hardware bugs, UltraDMA is only supported | |
13 | * on the 646U2 and not on the 646U. | |
