-;* The startup sequence for DUET disk boot sector is:
-;*
-;* 1, LegacyBios check 0xAA55 signature at boot sectore offset 0x1FE to judget
-;* whether disk/partition is bootable.
-;* 2, LegacyBios will load boot sector to 0x7c00 in real mode, pass BPB data and
-;* hand off control to 0x7c00 code.
-;* 3, boot sector code simply parse FAT format in boot disk and find EfiLdr binary file
-;* and EfiVar.bin if exists. For first boot, EfiVar.bin does not exist.
-;* 4, boot sector load the first sector of EfiLdr binary which is start.com to

-;* 5, boot sector handoff control to 0x2000:0x0000 for start.com binary.

-# Note: The EDK II DSC file is not used to specify how compiled binary images get placed

-# It is the FDF file that contains information on combining binary files into firmware
-# volume images, whose concept is beyond UEFI and is described in PI specification.
-# Binary modules do not need to be listed in this section, as they should be
-# specified in the FDF file. For example: Shell binary (Shell_Full.efi), FAT binary (Fat.efi),
-# Logo (Logo.bmp), and etc.
-# There may also be modules listed in this section that are not required in the FDF file,
-# When a module listed here is excluded from FDF file, then UEFI-compliant binary will be
-# generated for it, but the binary will not be put into any firmware volume.

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

- Returns the information about the optimum modes for the specified IDE device.
-
- This function is used by the driver entity to obtain the optimum ATA modes for

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

- is the pointer to the response data buffer. The IdentifyData buffer is owned

- The IDE controller driver may consult various fields of EFI_IDENTIFY_DATA to

- may examine the vendor and type/mode field to match known bad drives.

- Disqualifies specific modes for an IDE device.

- This function allows the driver entity or other drivers (such as platform

- to recalculate modes. This function allows the driver entity and the IDE
- controller driver to negotiate the timings on a per-device basis. This function
- is useful in the case of drives that lie about their capabilities. An example
- is when the IDE device fails to accept the timing modes that are calculated
- by the IDE controller driver based on the response to the Identify Drive command.
-
- If the driver entity does not want to limit the ATA timing modes and leave that
- decision to the IDE controller driver, it can either not call this function for
- the given device or call this function and set the Valid flag to FALSE for all
- modes that are listed in EFI_ATA_COLLECTIVE_MODE.
-
- The driver entity may disqualify modes for a device in any order and any number

- This function can be called multiple times to invalidate multiple modes of the

- specification for more information on PIO modes.
-
- For Serial ATA (SATA) controllers, this member function can be used to disqualify

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