| 8 | The Intelligent Input/Output (I2O) architecture allows hardware |
| 9 | drivers to be split into two parts: an operating system specific |
| 10 | module called the OSM and an hardware specific module called the |
| 11 | HDM. The OSM can talk to a whole range of HDM's, and ideally the |
| 12 | HDM's are not OS dependent. This allows for the same HDM driver to |
| 13 | be used under different operating systems if the relevant OSM is in |
| 14 | place. In order for this to work, you need to have an I2O interface |
| 15 | adapter card in your computer. This card contains a special I/O |
| 16 | processor (IOP), thus allowing high speeds since the CPU does not |
| 17 | have to deal with I/O. |
| 18 | |
| 19 | If you say Y here, you will get a choice of interface adapter |
| 20 | drivers and OSM's with the following questions. |
| 21 | |
| 22 | To compile this support as a module, choose M here: the |
| 23 | modules will be called i2o_core. |
| 24 | |
| 25 | If unsure, say N. |

| 30 | help |
| 31 | Say Y for support of the configuration interface for the I2O adapters. |
| 32 | If you have a RAID controller from Adaptec and you want to use the |
| 33 | raidutils to manage your RAID array, you have to say Y here. |

| 49 | Include support for the I2O Bus Adapter OSM. The Bus Adapter OSM |
| 50 | provides access to the busses on the I2O controller. The main purpose |
| 51 | is to rescan the bus to find new devices. |

| 58 | depends on I2O |
| 59 | help |
| 60 | Include support for the I2O Block OSM. The Block OSM presents disk |
| 61 | and other structured block devices to the operating system. If you |
| 62 | are using an RAID controller, you could access the array only by |
| 63 | the Block OSM driver. But it is possible to access the single disks |
| 64 | by the SCSI OSM driver, for example to monitor the disks. |

| 73 | Allows direct SCSI access to SCSI devices on a SCSI or FibreChannel |
| 74 | I2O controller. You can use both the SCSI and Block OSM together if |
| 75 | you wish. To access a RAID array, you must use the Block OSM driver. |
| 76 | But you could use the SCSI OSM driver to monitor the single disks. |
