+
+Module Name:
+
+ WinNtBlockIo.c
+
+Abstract:
+
+ Produce block IO abstractions for real devices on your PC using Win32 APIs.
+ The configuration of what devices to mount or emulate comes from NT
+ environment variables. The variables must be visible to the Microsoft*
+ Developer Studio for them to work.
+
+ <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_WIN_NT_VIRTUAL_DISKS =
+ <F | R><O | W>;<block count>;<block size>[!...]
+
+ EFI_WIN_NT_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_WIN_NT_VIRTUAL_DISKS=FW;40960;512
+
+ A 1.44MB emulated floppy with a block size of 1024 would look like:
+ EFI_WIN_NT_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_WIN_NT_PHYSICAL_DISKS=B:RW;245760;512
+
+ Thus a standard CD-ROM floppy would look like:
+ EFI_WIN_NT_PHYSICAL_DISKS=Z:RO;307200;2048
