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

xpram. If unsure, say "N".
