| 39 | * This driver handles legacy (that is "ISA/VLB side") IDE ports found |
| 40 | * on PC class systems. There are three hybrid devices that are exceptions |
| 41 | * The Cyrix 5510/5520 where a pre SFF ATA device is on the bridge and |
| 42 | * the MPIIX where the tuning is PCI side but the IDE is "ISA side". |
| 43 | * |
| 44 | * Specific support is included for the ht6560a/ht6560b/opti82c611a/ |
