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.
|
|
|
|
UNIX 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 UNIX 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
