10 | Select this option if you want to use your expanded storage on S/390 | |

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". | |

61 | help | |
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. | |
