8config EDD
9        tristate "BIOS Enhanced Disk Drive calls determine boot disk"
10        depends on !IA64
11        depends on !XEN
12        help
13          Say Y or M here if you want to enable BIOS Enhanced Disk Drive
14          Services real mode BIOS calls to determine which disk
15          BIOS tries boot from.  This information is then exported via sysfs.
16
17          This option is experimental and is known to fail to boot on some
18          obscure configurations. Most disk controller BIOS vendors do
19          not yet implement this feature.

21config EFI_VARS
22        tristate "EFI Variable Support via sysfs"
23        depends on EFI
24        default n
25        help
26          If you say Y here, you are able to get EFI (Extensible Firmware
27          Interface) variable information via sysfs.  You may read,
28          write, create, and destroy EFI variables through this interface.
29
30          Note that using this driver in concert with efibootmgr requires
31          at least test release version 0.5.0-test3 or later, which is
32          available from Matt Domsch's website located at:
33          <http://linux.dell.com/efibootmgr/testing/efibootmgr-0.5.0-test3.tar.gz>
34
35          Subsequent efibootmgr releases may be found at:

38config EFI_PCDP
39        bool "Console device selection via EFI PCDP or HCDP table"
40        depends on ACPI && EFI && IA64
41        default y if IA64
42        help
43          If your firmware supplies the PCDP table, and you want to
44          automatically use the primary console device it describes
45          as the Linux console, say Y here.
46
47          If your firmware supplies the HCDP table, and you want to
48          use the first serial port it describes as the Linux console,
49          say Y here.  If your EFI ConOut path contains only a UART
50          device, it will become the console automatically.  Otherwise,
51          you must specify the "console=hcdp" kernel boot argument.
52
53          Neither the PCDP nor the HCDP affects naming of serial devices,
54          so a serial console may be /dev/ttyS0, /dev/ttyS1, etc, depending
55          on how the driver discovers devices.
56
57          You must also enable the appropriate drivers (serial, VGA, etc.)

61config DELL_RBU
62        tristate "BIOS update support for DELL systems via sysfs"
63        depends on X86
64        select FW_LOADER
65        help
66         Say m if you want to have the option of updating the BIOS for your
67         DELL system. Note you need a Dell OpenManage or Dell Update package (DUP)
68         supporting application to comunicate with the BIOS regarding the new
69         image for the image update to take effect.
70         See <file:Documentation/dell_rbu.txt> for more details on the driver.

72config DCDBAS
73        tristate "Dell Systems Management Base Driver"
74        depends on X86
75        help
76          The Dell Systems Management Base Driver provides a sysfs interface
77          for systems management software to perform System Management
78          Interrupts (SMIs) and Host Control Actions (system power cycle or
79          power off after OS shutdown) on certain Dell systems.
80
81          See <file:Documentation/dcdbas.txt> for more details on the driver
82          and the Dell systems on which Dell systems management software makes
83          use of this driver.
84
85          Say Y or M here to enable the driver for use by Dell systems
86          management software such as Dell OpenManage.
