+
+ Virtual Disks: These devices use a file to emulate a hard disk or removable
+ media device.
+
+ Thus a 20 MB emulated hard drive would look like:
+ EFI_UNIX_VIRTUAL_DISKS=FW;40960;512
+
+ A 1.44MB emulated floppy with a block size of 1024 would look like:
+ EFI_UNIX_VIRTUAL_DISKS=RW;1440;1024
+
+ Physical Disks: These devices use NT to open a real device in your system
+
+ Thus a 120 MB floppy would look like:
+ EFI_UNIX_PHYSICAL_DISKS=B:RW;245760;512
+
+ Thus a standard CD-ROM floppy would look like:
+ EFI_UNIX_PHYSICAL_DISKS=Z:RO;307200;2048

+ Routine Description:
+ Blt pixels from the rectangle (Width X Height) formed by the BltBuffer
+ onto the graphics screen starting a location (X, Y). (0, 0) is defined as
+ the upper left hand side of the screen. (X, Y) can be outside of the
+ current screen geometry and the BltBuffer will be cliped when it is
+ displayed. X and Y can be negative or positive. If Width or Height is
+ bigger than the current video screen the image will be clipped.
+
+ Arguments:
+ This - Protocol instance pointer.
+ X - X location on graphics screen.
+ Y - Y location on the graphics screen.
+ Width - Width of BltBuffer.
+ Height - Hight of BltBuffer
+ BltOperation - Operation to perform on BltBuffer and video memory
+ BltBuffer - Buffer containing data to blt into video buffer. This
+ buffer has a size of Width*Height*sizeof(EFI_UGA_PIXEL)
+ SourceX - If the BltOperation is a EfiCopyBlt this is the source
+ of the copy. For other BLT operations this argument is not
+ used.
+ SourceX - If the BltOperation is a EfiCopyBlt this is the source

+ Returns:

+
+Abstract:
+
+This following section documents the envirnoment variables for the Win NT
+build. These variables are used to define the (virtual) hardware
+configuration of the NT environment
+
+A ! can be used to seperate multiple instances in a variable. Each
+instance represents a seperate hardware device.
+
+EFI_UNIX_PHYSICAL_DISKS - maps to drives on your system
+EFI_UNIX_VIRTUAL_DISKS - maps to a device emulated by a file
+EFI_UNIX_FILE_SYSTEM - mouts a directory as a file system
+EFI_UNIX_CONSOLE - make a logical comand line window (only one!)
+EFI_UNIX_UGA - Builds UGA Windows of Width and Height
+
+ <F>ixed - Fixed disk like a hard drive.
+ <R>emovable - Removable media like a floppy or CD-ROM.
+ Read <O>nly - Write protected device.
+ Read <W>rite - Read write device.
+ <block count> - Decimal number of blocks a device supports.
+ <block size> - Decimal number of bytes per block.
+
+ NT envirnonment variable contents. '<' and '>' are not part of the variable,
+ they are just used to make this help more readable. There should be no
+ spaces between the ';'. Extra spaces will break the variable. A '!' is
+ used to seperate multiple devices in a variable.
+
+ EFI_UNIX_VIRTUAL_DISKS =
+ <F | R><O | W>;<block count>;<block size>[!...]
+
+ EFI_UNIX_PHYSICAL_DISKS =
+ <drive letter>:<F | R><O | W>;<block count>;<block size>[!...]
+
+ Virtual Disks: These devices use a file to emulate a hard disk or removable
+ media device.
+
+ Thus a 20 MB emulated hard drive would look like:
+ EFI_UNIX_VIRTUAL_DISKS=FW;40960;512
+
+ A 1.44MB emulated floppy with a block size of 1024 would look like:
+ EFI_UNIX_VIRTUAL_DISKS=RW;1440;1024
+
+ Physical Disks: These devices use NT to open a real device in your system
+
+ Thus a 120 MB floppy would look like:
+ EFI_UNIX_PHYSICAL_DISKS=B:RW;245760;512
+
+ Thus a standard CD-ROM floppy would look like:
+ EFI_UNIX_PHYSICAL_DISKS=Z:RO;307200;2048
+
+ EFI_UNIX_FILE_SYSTEM =
+ <directory path>[!...]
+
+ Mounting the two directories C:\FOO and C:\BAR would look like:
+ EFI_UNIX_FILE_SYSTEM=c:\foo!c:\bar
+
+ EFI_UNIX_CONSOLE =
+ <window title>
+
+ Declaring a text console window with the title "My EFI Console" woild look like:
+ EFI_UNIX_CONSOLE=My EFI Console
+
+ EFI_UNIX_UGA =
+ <width> <height>[!...]
+
+ Declaring a two UGA windows with resolutions of 800x600 and 1024x768 would look like:
+ Example : EFI_UNIX_UGA=800 600!1024 768
+
+ EFI_UNIX_PASS_THROUGH =
+ <BaseAddress>;<Bus#>;<Device#>;<Function#>
+
+ Declaring a base address of 0xE0000000 (used for PCI Express devices)
+ and having NT32 talk to a device located at bus 0, device 1, function 0:
+ Example : EFI_UNIX_PASS_THROUGH=E000000;0;1;0

+
+ UnixBusDriver.h
+
+Abstract:
+
+This following section documents the PCD for the Unix
+build. These variables are used to define the (virtual) hardware
+configuration of the Unix environment
+
+A ! can be used to seperate multiple instances in a variable. Each
+instance represents a seperate hardware device.
+
+EFI_UNIX_PHYSICAL_DISKS - maps to drives on your system
+EFI_UNIX_VIRTUAL_DISKS - maps to a device emulated by a file
+EFI_UNIX_FILE_SYSTEM - mouts a directory as a file system
+EFI_UNIX_CONSOLE - make a logical comand line window (only one!)
+EFI_UNIX_UGA - Builds UGA Windows of Width and Height
+EFI_UNIX_SERIAL_PORT - maps physical serial ports
+EFI_UNIX_PASS_THRU - associates a device with our PCI support
+
+ <F>ixed - Fixed disk like a hard drive.
+ <R>emovable - Removable media like a floppy or CD-ROM.
+ Read <O>nly - Write protected device.
+ Read <W>rite - Read write device.
+ <block count> - Decimal number of blocks a device supports.
+ <block size> - Decimal number of bytes per block.
+
+ NT envirnonment variable contents. '<' and '>' are not part of the variable,
+ they are just used to make this help more readable. There should be no
+ spaces between the ';'. Extra spaces will break the variable. A '!' is
+ used to seperate multiple devices in a variable.
+
+ EFI_UNIX_VIRTUAL_DISKS =
+ <F | R><O | W>;<block count>;<block size>[!...]
+
+ EFI_UNIX_PHYSICAL_DISKS =
+ <drive letter>:<F | R><O | W>;<block count>;<block size>[!...]
+
+ Virtual Disks: These devices use a file to emulate a hard disk or removable
+ media device.
+
+ Thus a 20 MB emulated hard drive would look like:
+ EFI_UNIX_VIRTUAL_DISKS=FW;40960;512
+
+ A 1.44MB emulated floppy with a block size of 1024 would look like:
+ EFI_UNIX_VIRTUAL_DISKS=RW;1440;1024
+
+ Physical Disks: These devices use NT to open a real device in your system
+
+ Thus a 120 MB floppy would look like:
+ EFI_UNIX_PHYSICAL_DISKS=B:RW;245760;512
+
+ Thus a standard CD-ROM floppy would look like:
+ EFI_UNIX_PHYSICAL_DISKS=Z:RO;307200;2048
+
+ EFI_UNIX_FILE_SYSTEM =
+ <directory path>[!...]
+
+ Mounting the two directories C:\FOO and C:\BAR would look like:
+ EFI_UNIX_FILE_SYSTEM=c:\foo!c:\bar
+
+ EFI_UNIX_CONSOLE =
+ <window title>
+
+ Declaring a text console window with the title "My EFI Console" woild look like:
+ EFI_UNIX_CONSOLE=My EFI Console
+
+ EFI_UNIX_UGA =
+ <width> <height>[!...]
+
+ Declaring a two UGA windows with resolutions of 800x600 and 1024x768 would look like:
+ Example : EFI_UNIX_UGA=800 600!1024 768
+
+ EFI_UNIX_SERIAL_PORT =
+ <port name>[!...]
+
+ Declaring two serial ports on COM1 and COM2 would look like:
+ Example : EFI_UNIX_SERIAL_PORT=COM1!COM2
+
+ EFI_UNIX_PASS_THROUGH =
+ <BaseAddress>;<Bus#>;<Device#>;<Function#>
+
+ Declaring a base address of 0xE0000000 (used for PCI Express devices)
+ and having NT32 talk to a device located at bus 0, device 1, function 0:
+ Example : EFI_UNIX_PASS_THROUGH=E000000;0;1;0
