16 | Abstract:\r |
17 | \r |
18 | This following section documents the envirnoment variables for the Win NT \r |
19 | build. These variables are used to define the (virtual) hardware \r |
20 | configuration of the NT environment\r |
21 | \r |
22 | A ! can be used to seperate multiple instances in a variable. Each \r |
23 | instance represents a seperate hardware device. \r |
24 | \r |
25 | EFI_WIN_NT_PHYSICAL_DISKS - maps to drives on your system\r |
26 | EFI_WIN_NT_VIRTUAL_DISKS - maps to a device emulated by a file\r |
27 | EFI_WIN_NT_FILE_SYSTEM - mouts a directory as a file system\r |
28 | EFI_WIN_NT_CONSOLE - make a logical comand line window (only one!)\r |
29 | EFI_WIN_NT_UGA - Builds UGA Windows of Width and Height\r |
30 | EFI_WIN_NT_SERIAL_PORT - maps physical serial ports\r |
31 | \r |
32 | <F>ixed - Fixed disk like a hard drive.\r |
33 | <R>emovable - Removable media like a floppy or CD-ROM.\r |
34 | Read <O>nly - Write protected device.\r |
35 | Read <W>rite - Read write device.\r |
36 | <block count> - Decimal number of blocks a device supports.\r |
37 | <block size> - Decimal number of bytes per block.\r |
38 | \r |
39 | NT envirnonment variable contents. '<' and '>' are not part of the variable, \r |
40 | they are just used to make this help more readable. There should be no \r |
41 | spaces between the ';'. Extra spaces will break the variable. A '!' is \r |
42 | used to seperate multiple devices in a variable.\r |
43 | \r |
44 | EFI_WIN_NT_VIRTUAL_DISKS = \r |
45 | <F | R><O | W>;<block count>;<block size>[!...]\r |
46 | \r |
47 | EFI_WIN_NT_PHYSICAL_DISKS =\r |
48 | <drive letter>:<F | R><O | W>;<block count>;<block size>[!...]\r |
49 | \r |
50 | Virtual Disks: These devices use a file to emulate a hard disk or removable\r |
51 | media device. \r |
52 | \r |
53 | Thus a 20 MB emulated hard drive would look like:\r |
54 | EFI_WIN_NT_VIRTUAL_DISKS=FW;40960;512\r |
55 | \r |
56 | A 1.44MB emulated floppy with a block size of 1024 would look like:\r |
57 | EFI_WIN_NT_VIRTUAL_DISKS=RW;1440;1024\r |
58 | \r |
59 | Physical Disks: These devices use NT to open a real device in your system\r |
60 | \r |
61 | Thus a 120 MB floppy would look like:\r |
62 | EFI_WIN_NT_PHYSICAL_DISKS=B:RW;245760;512\r |
63 | \r |
64 | Thus a standard CD-ROM floppy would look like:\r |
65 | EFI_WIN_NT_PHYSICAL_DISKS=Z:RO;307200;2048\r |
66 | \r |
67 | EFI_WIN_NT_FILE_SYSTEM = \r |
68 | <directory path>[!...]\r |
69 | \r |
70 | Mounting the two directories C:\FOO and C:\BAR would look like:\r |
71 | EFI_WIN_NT_FILE_SYSTEM=c:\foo!c:\bar\r |
72 | \r |
73 | EFI_WIN_NT_CONSOLE = \r |
74 | <window title>\r |
75 | \r |
76 | Declaring a text console window with the title "My EFI Console" woild look like:\r |
77 | EFI_WIN_NT_CONSOLE=My EFI Console\r |
78 | \r |
79 | EFI_WIN_NT_UGA = \r |
80 | <width> <height>[!...]\r |
81 | \r |
82 | Declaring a two UGA windows with resolutions of 800x600 and 1024x768 would look like:\r |
83 | Example : EFI_WIN_NT_UGA=800 600!1024 768\r |
84 | \r |
85 | EFI_WIN_NT_SERIAL_PORT = \r |
86 | <port name>[!...]\r |
87 | \r |
88 | Declaring two serial ports on COM1 and COM2 would look like:\r |
89 | Example : EFI_WIN_NT_SERIAL_PORT=COM1!COM2\r |
90 | \r |
91 | EFI_WIN_NT_PASS_THROUGH =\r |
92 | <BaseAddress>;<Bus#>;<Device#>;<Function#>\r |
93 | \r |
94 | Declaring a base address of 0xE0000000 (used for PCI Express devices)\r |
95 | and having NT32 talk to a device located at bus 0, device 1, function 0:\r |
96 | Example : EFI_WIN_NT_PASS_THROUGH=E000000;0;1;0\r |
