| 6 | The Intelligent Input/Output (I2O) architecture allows hardware |
| 7 | drivers to be split into two parts: an operating system specific |
| 8 | module called the OSM and an hardware specific module called the |
| 9 | HDM. The OSM can talk to a whole range of HDM's, and ideally the |
| 10 | HDM's are not OS dependent. This allows for the same HDM driver to |
| 11 | be used under different operating systems if the relevant OSM is in |
| 12 | place. In order for this to work, you need to have an I2O interface |
| 13 | adapter card in your computer. This card contains a special I/O |
| 14 | processor (IOP), thus allowing high speeds since the CPU does not |
| 15 | have to deal with I/O. |
| 16 | |
| 17 | If you say Y here, you will get a choice of interface adapter |
| 18 | drivers and OSM's with the following questions. |
