2 menu "I2O device support"
6 depends on PCI && !64BIT
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.
19 If you say Y here, you will get a choice of interface adapter
20 drivers and OSM's with the following questions.
22 To compile this support as a module, choose M here: the
23 modules will be called i2o_core and i2o_config.
28 tristate "I2O PCI support"
31 Say Y for support of PCI bus I2O interface adapters. Currently this
32 is the only variety supported, so you should say Y.
34 To compile this support as a module, choose M here: the
35 module will be called i2o_pci.
38 tristate "I2O Block OSM"
41 Include support for the I2O Block OSM. The Block OSM presents disk
42 and other structured block devices to the operating system. If you
43 are using an RAID controller, you could access the array only by
44 the Block OSM driver. But it is possible to access the single disks
45 by the SCSI OSM driver, for example to monitor the disks.
47 To compile this support as a module, choose M here: the
48 module will be called i2o_block.
51 tristate "I2O SCSI OSM"
52 depends on I2O && SCSI
54 Allows direct SCSI access to SCSI devices on a SCSI or FibreChannel
55 I2O controller. You can use both the SCSI and Block OSM together if
56 you wish. To access a RAID array, you must use the Block OSM driver.
57 But you could use the SCSI OSM driver to monitor the single disks.
59 To compile this support as a module, choose M here: the
60 module will be called i2o_scsi.
63 tristate "I2O /proc support"
66 If you say Y here and to "/proc file system support", you will be
67 able to read I2O related information from the virtual directory
70 To compile this support as a module, choose M here: the
71 module will be called i2o_proc.
