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".

62 This driver provides an additional interface to the channel measurement
63 facility, which is normally accessed though sysfs, with a set of
64 ioctl functions specific to the dasd driver.
65 This is only needed if you want to use applications written for
66 linux-2.4 dasd channel measurement facility interface.
