Firmware Drivers

 * Option: EDD
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) BIOS Enhanced Disk Drive calls determine boot disk (EXPERIMENTAL)
 * depends on EXPERIMENTAL
 * depends on !IA64
 * 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.


 * Option: EFI_VARS
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) EFI Variable Support via sysfs
 * depends on EFI
 * default n
 * 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: 
 * Subsequent efibootmgr releases may be found at: 


 * Option: EFI_PCDP
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) Console device selection via EFI PCDP or HCDP table
 * depends on ACPI && EFI && IA64
 * default y if IA64
 * 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.)
 * See 


 * Option: DELL_RBU
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) BIOS update support for DELL systems via sysfs
 * depends on X86
 * select FW_LOADER
 * Say m if you want to have the option of updating the BIOS for yourDELL system. Note you need a Dell OpenManage or Dell Update package (DUP)supporting application to communicate with the BIOS regarding the newimage for the image update to take effect.See  for more details on the driver.


 * Option: DCDBAS
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) Dell Systems Management Base Driver
 * depends on X86
 * 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  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.
