| 10 | Select this option if you want to use your expanded storage on S/390 | |
| 11 | or zSeries as a disk. This is useful as a _fast_ swap device if you | |
| 12 | want to access more than 2G of memory when running in 31 bit mode. | |
| 13 | This option is also available as a module which will be called | |
| 14 | xpram. If unsure, say "N". | |
