It was invented in the era when UEFI environment is hard to find.
Since now UEFI is very popular in PC area, we could stop the
official support of this package and remove it from the master.

-Developer's UEFI Emulation (DUET) on Edk2\r
-\r
-A. Build DUET image on Windows Platform\r
-========================================\r
-1. Tools preparation\r
-\r
- To build DUET image, Visual Studio is required:\r
- 1). Base on below link to create Visual Studio build environment.\r
- https://github.com/tianocore/tianocore.github.io/wiki/Windows-systems\r
-\r
-2. Build Duet Platform module\r
-\r
- 1). run cmd.exe to open command line window.\r
- 2). enter workspace root directory such as c:\edk2_tree\r
- 3). set the environment variable EDK_TOOLS_BIN to point at the BaseTools binaries directory\r
- i.e., "set EDK_TOOLS_BIN=c:\edk2-BaseTools-win32"\r
- 4). run "edksetup.bat"\r
- 5). run "build -p DuetPkg\DuetPkgIa32.dsc -a IA32 -t VS2015x86" for IA32 architecture platform (using 64-bit VS2015 for example) or\r
- "build -p DuetPkg\DuetPkgX64.dsc -a X64 -t VS2015x86" for X64 architecture platform.\r
-\r
- NOTE: The post build script 'PostBuild.sh' will be automatically called after the build command.\r
-\r
-\r
-Create bootable disk\r
-======================\r
-\r
-3. Create boot disk\r
- The following steps are same for IA32 architecture platform or X64 architecture platform.\r
-\r
-3.1 Create floppy boot disk\r
- 1). enter <Workspace>\DuetPkg directory.\r
- 2). Insert a floppy disk to drive\r
- 3). run "CreateBootDisk.bat floppy a: FAT12 IA32" if floppy drive is a: disk and Arch to boot is IA32.\r
- or\r
- run "CreateBootDisk.bat floppy a: FAT12 X64" if floppy drive is a: disk and Arch to boot is X64.\r
-3.2 Create usb boot disk\r
- 1). enter <Workspace>\DuetPkg directory.\r
- 2). Plugin usb disk\r
- 3). run "CreateBootDisk.bat usb e: FAT16 IA32" if usb drive is e: and FAT format is FAT16 and Arch to boot is IA32.\r
- or "CreateBootDisk.bat usb e: FAT16 X64" if usb drive is e: and FAT format is FAT16 and Arch to boot is X64.\r
- or "CreateBootDisk.bat usb e: FAT32 IA32" if usb drive is e: and FAT format is FAT32 and Arch to boot is IA32.\r
- or "CreateBootDisk.bat usb e: FAT32 X64" if usb drive is e: and FAT format is FAT32 and Arch to boot is X64.\r
- 4). UnPlug usb disk and plugin it again.\r
- 5). run "CreateBootDisk.bat usb e: FAT16 IA32 step2" if usb drive is e: and FAT format is FAT16 and Arch to boot is IA32.\r
- or "CreateBootDisk.bat usb e: FAT16 X64 step2" if usb drive is e: and FAT format is FAT16 and Arch to boot is X64.\r
- or "CreateBootDisk.bat usb e: FAT32 IA32 step2" if usb drive is e: and FAT format is FAT32 and Arch to boot is IA32.\r
- or "CreateBootDisk.bat usb e: FAT32 X64 step2" if usb drive is e: and FAT format is FAT32 and Arch to boot is X64.\r
-\r
-B. Build DUET image on Linux Platform\r
-======================================\r
-1. Tools preparation\r
-\r
- To build DUET image, GCC installation (4.4+) is required:\r
- 1). Base on below link to create GCC build environment.\r
- https://github.com/tianocore/tianocore.github.io/wiki/Using-EDK-II-with-Native-GCC\r
-\r
-2. Build Duet Platform module\r
-\r
- 1). Open the terminal.\r
- 2). enter workspace root directory such as /edk2_tree\r
- 3). run ". edksetup.sh BaseTools"\r
- 4). run "build -p DuetPkg/DuetPkgIa32.dsc -a IA32 -t GCC49" for IA32 architecture platform (using GCC 4.9 for example) or\r
- "build -p DuetPkg/DuetPkgX64.dsc -a X64 -t GCC49" for X64 architecture platform.\r
-\r
- NOTE: The post build script 'PostBuild.sh' will be automatically called after the build command.\r
- After post build action, you should check the size of EfiLdr at $WORKSPACE/Build/DuetPkgIA32(DuetPkgX64)/DEBUG_GCC49 directory, it must less than 470k.\r
- If not, you should manually remove some unnecessary drivers at DuetPkg.fdf file.\r
-\r
-3. Create bootable disk\r
- The following steps are same for IA32 architecture platform or X64 architecture platform.\r
-\r
-3.1 Create floppy boot disk\r
- 1). enter /edk2_tree/DuetPkg directory.\r
- 2). Insert a floppy disk to drive\r
- 3). run "CreateBootDisk.sh" to build floppy drive\r
- such as "./CreateBootDisk.sh floppy /media/floppy0 /dev/fd0 FAT12 IA32"\r
-\r
-3.2 Create usb boot disk\r
- 1). enter /edk2_tree/DuetPkg directory.\r
- 2). Plugin usb disk\r
- 3). run "CreateBootDisk.sh" to build usb drive\r
- such as "./CreateBootDisk.sh usb /media/usb0 /dev/sdb0 FAT16 IA32"\r
- 4). UnPlug usb disk and plugin it again.\r

-\r
- This function is used by the driver entity to obtain the optimum ATA modes for\r

- while calculating the mode:\r
- - The IdentifyData inputs to EFI_IDE_CONTROLLER_INIT_PROTOCOL.SubmitData()\r
- - The BadModes inputs to EFI_IDE_CONTROLLER_INIT_PROTOCOL.DisqualifyMode()\r

- EFI_IDE_CONTROLLER_INIT_PROTOCOL.CalculateMode() for any device in the same group. \r
- \r
- The IDE controller driver will use controller- and possibly platform-specific \r
- algorithms to arrive at SupportedModes. The IDE controller may base its \r
- decision on user preferences and other considerations as well. This function \r
- may be called multiple times because the driver entity may renegotiate the mode \r
- with the IDE controller driver using EFI_IDE_CONTROLLER_INIT_PROTOCOL.DisqualifyMode().\r
- \r
- The driver entity may collect timing information for various devices in any \r
- order. The driver entity is responsible for making sure that all the dependencies\r

- Submits the device information to the IDE controller driver.\r
-\r
- This function is used by the driver entity to pass detailed information about \r
- a particular device to the IDE controller driver. The driver entity obtains \r
- this information by issuing an ATA or ATAPI IDENTIFY_DEVICE command. IdentifyData\r
- is the pointer to the response data buffer. The IdentifyData buffer is owned \r

- \r
- The IDE controller driver may consult various fields of EFI_IDENTIFY_DATA to \r
- compute the optimum mode for the device. These fields are not limited to the \r
- timing information. For example, an implementation of the IDE controller driver \r
- may examine the vendor and type/mode field to match known bad drives. \r
- \r

- submits information for all the devices belonging to the enumeration group \r
- before EFI_IDE_CONTROLLER_INIT_PROTOCOL.CalculateMode() is called for any device\r
- in that enumeration group. If a device is absent, EFI_IDE_CONTROLLER_INIT_PROTOCOL.SubmitData()\r
- should be called with IdentifyData set to NULL. The IDE controller driver may \r
- not have any other mechanism to know whether a device is present or not. Therefore, \r

-/**\r
- Disqualifies specific modes for an IDE device.\r
-\r
- This function allows the driver entity or other drivers (such as platform \r
- drivers) to reject certain timing modes and request the IDE controller driver\r
- to recalculate modes. This function allows the driver entity and the IDE \r
- controller driver to negotiate the timings on a per-device basis. This function \r
- is useful in the case of drives that lie about their capabilities. An example \r
- is when the IDE device fails to accept the timing modes that are calculated \r
- by the IDE controller driver based on the response to the Identify Drive command.\r
-\r
- If the driver entity does not want to limit the ATA timing modes and leave that \r
- decision to the IDE controller driver, it can either not call this function for \r
- the given device or call this function and set the Valid flag to FALSE for all \r
- modes that are listed in EFI_ATA_COLLECTIVE_MODE.\r
- \r
- The driver entity may disqualify modes for a device in any order and any number \r
- of times.\r
- \r
- This function can be called multiple times to invalidate multiple modes of the \r
- same type (e.g., Programmed Input/Output [PIO] modes 3 and 4). See the ATA/ATAPI \r
- specification for more information on PIO modes. \r
- \r
- For Serial ATA (SATA) controllers, this member function can be used to disqualify\r
- a higher transfer rate mode on a given channel. For example, a platform driver\r
- may inform the IDE controller driver to not use second-generation (Gen2) speeds \r
- for a certain SATA drive.\r

-/**\r
- Returns the information about the optimum modes for the specified IDE device.\r
-\r
- This function is used by the driver entity to obtain the optimum ATA modes for\r
- a specific device. The IDE controller driver takes into account the following \r
- while calculating the mode:\r
- - The IdentifyData inputs to EFI_IDE_CONTROLLER_INIT_PROTOCOL.SubmitData()\r
- - The BadModes inputs to EFI_IDE_CONTROLLER_INIT_PROTOCOL.DisqualifyMode()\r
-\r
- The driver entity is required to call EFI_IDE_CONTROLLER_INIT_PROTOCOL.SubmitData() \r
- for all the devices that belong to an enumeration group before calling \r
- EFI_IDE_CONTROLLER_INIT_PROTOCOL.CalculateMode() for any device in the same group. \r
- \r
- The IDE controller driver will use controller- and possibly platform-specific \r
- algorithms to arrive at SupportedModes. The IDE controller may base its \r
- decision on user preferences and other considerations as well. This function \r
- may be called multiple times because the driver entity may renegotiate the mode \r
- with the IDE controller driver using EFI_IDE_CONTROLLER_INIT_PROTOCOL.DisqualifyMode().\r
- \r
- The driver entity may collect timing information for various devices in any \r
- order. The driver entity is responsible for making sure that all the dependencies\r
- are satisfied. For example, the SupportedModes information for device A that \r
- was previously returned may become stale after a call to \r
- EFI_IDE_CONTROLLER_INIT_PROTOCOL.DisqualifyMode() for device B.\r
- \r
- The buffer SupportedModes is allocated by the callee because the caller does \r
- not necessarily know the size of the buffer. The type EFI_ATA_COLLECTIVE_MODE \r
- is defined in a way that allows for future extensibility and can be of variable \r
- length. This memory pool should be deallocated by the caller when it is no \r
- longer necessary. \r
- \r
- The IDE controller driver for a Serial ATA (SATA) controller can use this \r
- member function to force a lower speed (first-generation [Gen1] speeds on a \r
- second-generation [Gen2]-capable hardware). The IDE controller driver can \r
- also allow the driver entity to stay with the speed that has been negotiated \r
