|  | config I2O | 
|  | tristate "I2O support" | 
|  | depends on PCI | 
|  | ---help--- | 
|  | The Intelligent Input/Output (I2O) architecture allows hardware | 
|  | drivers to be split into two parts: an operating system specific | 
|  | module called the OSM and an hardware specific module called the | 
|  | HDM. The OSM can talk to a whole range of HDM's, and ideally the | 
|  | HDM's are not OS dependent. This allows for the same HDM driver to | 
|  | be used under different operating systems if the relevant OSM is in | 
|  | place. In order for this to work, you need to have an I2O interface | 
|  | adapter card in your computer. This card contains a special I/O | 
|  | processor (IOP), thus allowing high speeds since the CPU does not | 
|  | have to deal with I/O. | 
|  |  | 
|  | If you say Y here, you will get a choice of interface adapter | 
|  | drivers and OSM's with the following questions. | 
|  |  | 
|  | To compile this support as a module, choose M here: the | 
|  | modules will be called i2o_core. | 
|  |  | 
|  | If unsure, say N. | 
|  |  | 
|  | config I2O_LCT_NOTIFY_ON_CHANGES | 
|  | bool "Enable LCT notification" | 
|  | depends on I2O | 
|  | default y | 
|  | ---help--- | 
|  | Only say N here if you have a I2O controller from SUN. The SUN | 
|  | firmware doesn't support LCT notification on changes. If this option | 
|  | is enabled on such a controller the driver will hang up in a endless | 
|  | loop. On all other controllers say Y. | 
|  |  | 
|  | If unsure, say Y. | 
|  |  | 
|  | config I2O_EXT_ADAPTEC | 
|  | bool "Enable Adaptec extensions" | 
|  | depends on I2O | 
|  | default y | 
|  | ---help--- | 
|  | Say Y for support of raidutils for Adaptec I2O controllers. You also | 
|  | have to say Y to "I2O Configuration support", "I2O SCSI OSM" below | 
|  | and to "SCSI generic support" under "SCSI device configuration". | 
|  |  | 
|  | config I2O_EXT_ADAPTEC_DMA64 | 
|  | bool "Enable 64-bit DMA" | 
|  | depends on I2O_EXT_ADAPTEC && ( 64BIT || HIGHMEM64G ) | 
|  | default y | 
|  | ---help--- | 
|  | Say Y for support of 64-bit DMA transfer mode on Adaptec I2O | 
|  | controllers. | 
|  | Note: You need at least firmware version 3709. | 
|  |  | 
|  | config I2O_CONFIG | 
|  | tristate "I2O Configuration support" | 
|  | depends on I2O | 
|  | ---help--- | 
|  | Say Y for support of the configuration interface for the I2O adapters. | 
|  | If you have a RAID controller from Adaptec and you want to use the | 
|  | raidutils to manage your RAID array, you have to say Y here. | 
|  |  | 
|  | To compile this support as a module, choose M here: the | 
|  | module will be called i2o_config. | 
|  |  | 
|  | Note: If you want to use the new API you have to download the | 
|  | i2o_config patch from http://i2o.shadowconnect.com/ | 
|  |  | 
|  | config I2O_CONFIG_OLD_IOCTL | 
|  | bool "Enable ioctls (OBSOLETE)" | 
|  | depends on I2O_CONFIG | 
|  | default y | 
|  | ---help--- | 
|  | Enables old ioctls. | 
|  |  | 
|  | config I2O_BUS | 
|  | tristate "I2O Bus Adapter OSM" | 
|  | depends on I2O | 
|  | ---help--- | 
|  | Include support for the I2O Bus Adapter OSM. The Bus Adapter OSM | 
|  | provides access to the busses on the I2O controller. The main purpose | 
|  | is to rescan the bus to find new devices. | 
|  |  | 
|  | To compile this support as a module, choose M here: the | 
|  | module will be called i2o_bus. | 
|  |  | 
|  | config I2O_BLOCK | 
|  | tristate "I2O Block OSM" | 
|  | depends on I2O | 
|  | ---help--- | 
|  | Include support for the I2O Block OSM. The Block OSM presents disk | 
|  | and other structured block devices to the operating system. If you | 
|  | are using an RAID controller, you could access the array only by | 
|  | the Block OSM driver. But it is possible to access the single disks | 
|  | by the SCSI OSM driver, for example to monitor the disks. | 
|  |  | 
|  | To compile this support as a module, choose M here: the | 
|  | module will be called i2o_block. | 
|  |  | 
|  | config I2O_SCSI | 
|  | tristate "I2O SCSI OSM" | 
|  | depends on I2O && SCSI | 
|  | ---help--- | 
|  | Allows direct SCSI access to SCSI devices on a SCSI or FibreChannel | 
|  | I2O controller. You can use both the SCSI and Block OSM together if | 
|  | you wish. To access a RAID array, you must use the Block OSM driver. | 
|  | But you could use the SCSI OSM driver to monitor the single disks. | 
|  |  | 
|  | To compile this support as a module, choose M here: the | 
|  | module will be called i2o_scsi. | 
|  |  | 
|  | config I2O_PROC | 
|  | tristate "I2O /proc support" | 
|  | depends on I2O | 
|  | ---help--- | 
|  | If you say Y here and to "/proc file system support", you will be | 
|  | able to read I2O related information from the virtual directory | 
|  | /proc/i2o. | 
|  |  | 
|  | To compile this support as a module, choose M here: the | 
|  | module will be called i2o_proc. |
