  392. help
  393. Execute-In-Place allows the kernel to run from non-volatile storage
  394. directly addressable by the CPU, such as NOR flash. This saves RAM
  395. space since the text section of the kernel is not loaded from flash
  396. to RAM. Read-write sections, such as the data section and stack,
  397. are still copied to RAM. The XIP kernel is not compressed since
  398. it has to run directly from flash, so it will take more space to
  399. store it. The flash address used to link the kernel object files,
  400. and for storing it, is configuration dependent. Therefore, if you
  401. say Y here, you must know the proper physical address where to
  402. store the kernel image depending on your own flash memory usage.
  403. Also note that the make target becomes "make xipImage" rather than

  510. APM is a BIOS specification for saving power using several different
  511. techniques. This is mostly useful for battery powered laptops with
  512. APM compliant BIOSes. If you say Y here, the system time will be
  513. reset after a RESUME operation, the /proc/apm device will provide
  514. battery status information, and user-space programs will receive
  515. notification of APM "events" (e.g. battery status change).
  516. In order to use APM, you will need supporting software. For location
  517. and more information, read <file:Documentation/pm.txt> and the
  518. Battery Powered Linux mini-HOWTO, available from
  519. <http://www.tldp.org/docs.html#howto>.
  520. This driver does not spin down disk drives (see the hdparm(8)
  521. manpage ("man 8 hdparm") for that), and it doesn't turn off
  522. VESA-compliant "green" monitors.

  524. much point in using this driver and you should say N. If you get
  525. random kernel OOPSes or reboots that don't seem to be related to

  527. APM in your BIOS).
