970 ---help---
971 APM is a BIOS specification for saving power using several different
972 techniques. This is mostly useful for battery powered laptops with
973 APM compliant BIOSes. If you say Y here, the system time will be
974 reset after a RESUME operation, the /proc/apm device will provide
975 battery status information, and user-space programs will receive
976 notification of APM "events" (e.g. battery status change).
977
978 If you select "Y" here, you can disable actual use of the APM
979 BIOS by passing the "apm=off" option to the kernel at boot time.
980
981 Note that the APM support is almost completely disabled for
982 machines with more than one CPU.
983
984 In order to use APM, you will need supporting software. For location
985 and more information, read <file:Documentation/pm.txt> and the
986 Battery Powered Linux mini-HOWTO, available from
987 <http://www.tldp.org/docs.html#howto>.
988
989 This driver does not spin down disk drives (see the hdparm(8)
990 manpage ("man 8 hdparm") for that), and it doesn't turn off
991 VESA-compliant "green" monitors.
992
993 This driver does not support the TI 4000M TravelMate and the ACER
994 486/DX4/75 because they don't have compliant BIOSes. Many "green"
995 desktop machines also don't have compliant BIOSes, and this driver
996 may cause those machines to panic during the boot phase.
997
998 Generally, if you don't have a battery in your machine, there isn't
999 much point in using this driver and you should say N. If you get
1000 random kernel OOPSes or reboots that don't seem to be related to
1001 anything, try disabling/enabling this option (or disabling/enabling
1002 APM in your BIOS).
1003
1004 Some other things you should try when experiencing seemingly random,
1005 "weird" problems:
1006
1007 1) make sure that you have enough swap space and that it is
1008 enabled.
1009 2) pass the "no-hlt" option to the kernel
1010 3) switch on floating point emulation in the kernel and pass
1011 the "no387" option to the kernel
1012 4) pass the "floppy=nodma" option to the kernel
1013 5) pass the "mem=4M" option to the kernel (thereby disabling
1014 all but the first 4 MB of RAM)
1015 6) make sure that the CPU is not over clocked.
1016 7) read the sig11 FAQ at <http://www.bitwizard.nl/sig11/>
1017 8) disable the cache from your BIOS settings
1018 9) install a fan for the video card or exchange video RAM
1019 10) install a better fan for the CPU
1020 11) exchange RAM chips
1021 12) exchange the motherboard.
1022
1023 To compile this driver as a module, choose M here: the
1024 module will be called apm.

1028config APM_IGNORE_USER_SUSPEND
1029 bool "Ignore USER SUSPEND"
1030 help
1031 This option will ignore USER SUSPEND requests. On machines with a
1032 compliant APM BIOS, you want to say N. However, on the NEC Versa M
1033 series notebooks, it is necessary to say Y because of a BIOS bug.
1034
1035config APM_DO_ENABLE
1036 bool "Enable PM at boot time"
1037 ---help---
1038 Enable APM features at boot time. From page 36 of the APM BIOS
1039 specification: "When disabled, the APM BIOS does not automatically
1040 power manage devices, enter the Standby State, enter the Suspend
1041 State, or take power saving steps in response to CPU Idle calls."
1042 This driver will make CPU Idle calls when Linux is idle (unless this
1043 feature is turned off -- see "Do CPU IDLE calls", below). This
1044 should always save battery power, but more complicated APM features
1045 will be dependent on your BIOS implementation. You may need to turn
1046 this option off if your computer hangs at boot time when using APM
1047 support, or if it beeps continuously instead of suspending. Turn
1048 this off if you have a NEC UltraLite Versa 33/C or a Toshiba
1049 T400CDT. This is off by default since most machines do fine without
1050 this feature.
1051
1052config APM_CPU_IDLE
1053 bool "Make CPU Idle calls when idle"
1054 help
1055 Enable calls to APM CPU Idle/CPU Busy inside the kernel's idle loop.
1056 On some machines, this can activate improved power savings, such as
1057 a slowed CPU clock rate, when the machine is idle. These idle calls
1058 are made after the idle loop has run for some length of time (e.g.,
1059 333 mS). On some machines, this will cause a hang at boot time or
1060 whenever the CPU becomes idle. (On machines with more than one CPU,
1061 this option does nothing.)

1063config APM_DISPLAY_BLANK
1064 bool "Enable console blanking using APM"
1065 help
1066 Enable console blanking using the APM. Some laptops can use this to
1067 turn off the LCD backlight when the screen blanker of the Linux
1068 virtual console blanks the screen. Note that this is only used by
1069 the virtual console screen blanker, and won't turn off the backlight
1070 when using the X Window system. This also doesn't have anything to
1071 do with your VESA-compliant power-saving monitor. Further, this
1072 option doesn't work for all laptops -- it might not turn off your
1073 backlight at all, or it might print a lot of errors to the console,
1074 especially if you are using gpm.
1075
1076config APM_ALLOW_INTS
1077 bool "Allow interrupts during APM BIOS calls"
1078 help
1079 Normally we disable external interrupts while we are making calls to
1080 the APM BIOS as a measure to lessen the effects of a badly behaving
1081 BIOS implementation. The BIOS should reenable interrupts if it
1082 needs to. Unfortunately, some BIOSes do not -- especially those in
1083 many of the newer IBM Thinkpads. If you experience hangs when you
1084 suspend, try setting this to Y. Otherwise, say N.
1085
1086config APM_REAL_MODE_POWER_OFF

1088 help
1089 Use real mode APM BIOS calls to switch off the computer. This is
1090 a work-around for a number of buggy BIOSes. Switch this option on if
1091 your computer crashes instead of powering off properly.

1123 ---help---
1124 On PCI systems, the BIOS can be used to detect the PCI devices and
1125 determine their configuration. However, some old PCI motherboards
1126 have BIOS bugs and may crash if this is done. Also, some embedded
1127 PCI-based systems don't have any BIOS at all. Linux can also try to
1128 detect the PCI hardware directly without using the BIOS.
1129
1130 With this option, you can specify how Linux should detect the
1131 PCI devices. If you choose "BIOS", the BIOS will be used,
1132 if you choose "Direct", the BIOS won't be used, and if you
1133 choose "MMConfig", then PCI Express MMCONFIG will be used.
1134 If you choose "Any", the kernel will try MMCONFIG, then the
1135 direct access method and falls back to the BIOS if that doesn't
1136 work. If unsure, go with the default, which is "Any".

1198 bus while maintaining backward compatibility with cards made for

1200 1995 when it was made obsolete by the PCI bus.
