Say Y or M here if you want to enable BIOS Enhanced Disk Drive
Services real mode BIOS calls to determine which disk
BIOS tries boot from.  This information is then exported via sysfs.

This option is experimental and is known to fail to boot on some
obscure configurations. Most disk controller BIOS vendors do
not yet implement this feature.

Say Y if you want EDD disabled by default, even though it is compiled into the
kernel. Say N if you want EDD enabled by default. EDD can be dynamically set
using the kernel parameter 'edd={on|skipmbr|off}'.

Add the firmware-provided (unmodified) memory map to /sys/firmware/memmap.
That memory map is used for example by kexec to set up parameter area
for the next kernel, but can also be used for debugging purposes.

See also Documentation/ABI/testing/sysfs-firmware-memmap.

If you say Y here, you are able to get EFI (Extensible Firmware
Interface) variable information via sysfs.  You may read,
write, create, and destroy EFI variables through this interface.

Note that using this driver in concert with efibootmgr requires
at least test release version 0.5.0-test3 or later, which is
available from Matt Domsch's website located at:
<http://linux.dell.com/efibootmgr/testing/efibootmgr-0.5.0-test3.tar.gz>

Subsequent efibootmgr releases may be found at:

If your firmware supplies the PCDP table, and you want to
automatically use the primary console device it describes
as the Linux console, say Y here.

If your firmware supplies the HCDP table, and you want to
use the first serial port it describes as the Linux console,
say Y here.  If your EFI ConOut path contains only a UART
device, it will become the console automatically.  Otherwise,
you must specify the "console=hcdp" kernel boot argument.

Neither the PCDP nor the HCDP affects naming of serial devices,
so a serial console may be /dev/ttyS0, /dev/ttyS1, etc, depending
on how the driver discovers devices.

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

Say m if you want to have the option of updating the BIOS for your
DELL system. Note you need a Dell OpenManage or Dell Update package (DUP)
supporting application to communicate with the BIOS regarding the new
image for the image update to take effect.
See <file:Documentation/dell_rbu.txt> for more details on the driver.

The Dell Systems Management Base Driver provides a sysfs interface
for systems management software to perform System Management
Interrupts (SMIs) and Host Control Actions (system power cycle or
power off after OS shutdown) on certain Dell systems.

See <file:Documentation/dcdbas.txt> for more details on the driver
and the Dell systems on which Dell systems management software makes
use of this driver.

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

Say Y here if you want to query SMBIOS/DMI system identification
information from userspace through /sys/class/dmi/id/ or if you want
DMI-based module auto-loading.

Say Y or M here to enable the exporting of the raw DMI table
data via sysfs.  This is useful for consuming the data without
requiring any access to /dev/mem at all.  Tables are found
under /sys/firmware/dmi when this option is enabled and
loaded.

This option enables the kernel to find the region of memory
in which the ISCSI Boot Firmware Table (iBFT) resides. This
is necessary for iSCSI Boot Firmware Table Attributes module to work
properly.

This option enables support for detection and exposing of iSCSI
Boot Firmware Table (iBFT) via sysfs to userspace. If you wish to
detect iSCSI boot parameters dynamically during system boot, say Y.
Otherwise, say N.

Enable helper functions for working with Analog Devices SigmaDSP
parts and binary firmwares produced by Analog Devices SigmaStudio.

If unsure, say N here.  Drivers that need these helpers will select
this option automatically.
