| 34 | /* All GDT Disk Array Controllers are fully supported by this driver. |
| 35 | * This includes the PCI/EISA/ISA SCSI Disk Array Controllers and the |
| 36 | * PCI Fibre Channel Disk Array Controllers. See gdth.h for a complete |
| 37 | * list of all controller types. |
| 38 | * |
| 39 | * If you have one or more GDT3000/3020 EISA controllers with |
| 40 | * controller BIOS disabled, you have to set the IRQ values with the |
| 41 | * command line option "gdth=irq1,irq2,...", where the irq1,irq2,... are |
| 42 | * the IRQ values for the EISA controllers. |
| 43 | * |
| 44 | * After the optional list of IRQ values, other possible |
| 45 | * command line options are: |
| 46 | * disable:Y disable driver |
| 47 | * disable:N enable driver |
| 48 | * reserve_mode:0 reserve no drives for the raw service |
| 49 | * reserve_mode:1 reserve all not init., removable drives |
| 50 | * reserve_mode:2 reserve all not init. drives |
| 51 | * reserve_list:h,b,t,l,h,b,t,l,... reserve particular drive(s) with |
| 52 | * h- controller no., b- channel no., |
| 53 | * t- target ID, l- LUN |
| 54 | * reverse_scan:Y reverse scan order for PCI controllers |
| 55 | * reverse_scan:N scan PCI controllers like BIOS |
| 56 | * max_ids:x x - target ID count per channel (1..MAXID) |
| 57 | * rescan:Y rescan all channels/IDs |
| 58 | * rescan:N use all devices found until now |

| 64 | * probe_eisa_isa:Y scan for EISA/ISA controllers |

| 72 | * Here is another example: "gdth=reserve_list:0,1,2,0,0,1,3,0,rescan:Y". |
| 73 | * |
| 74 | * When loading the gdth driver as a module, the same options are available. |
| 75 | * You can set the IRQs with "IRQ=...". However, the syntax to specify the |
| 76 | * options changes slightly. You must replace all ',' between options |
| 77 | * with ' ' and all ':' with '=' and you must use |
| 78 | * '1' in place of 'Y' and '0' in place of 'N'. |
