8 config 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.
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.
21 config 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.
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>
35 Subsequent efibootmgr releases may be found at:

38 config 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.
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.
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.
57 You must also enable the appropriate drivers (serial, VGA, etc.)

61 config 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.
72 config 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.
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.
85 Say Y or M here to enable the driver for use by Dell systems
86 management software such as Dell OpenManage.
